Execute Gradle builds in GitHub Actions workflows

This GitHub Action can be used to configure Gradle and optionally execute a Gradle build on any platform supported by GitHub Actions.

Use the action to setup Gradle

If you have an existing workflow invoking Gradle, you can add an initial "Setup Gradle" Step to benefit from caching, build-scan capture and other features of the gradle-build-action.

All subsequent Gradle invocations will benefit from this initial setup, via init scripts added to the Gradle User Home.

name: Run Gradle on PRs
on: pull_request
jobs:
  gradle:
    strategy:
      matrix:
        os: [ubuntu-latest, macos-latest, windows-latest]
    runs-on: ${{ matrix.os }}
    steps:
    - uses: actions/checkout@v3
    - uses: actions/setup-java@v3
      with:
        distribution: temurin
        java-version: 11
        
    - name: Setup Gradle
      uses: gradle/gradle-build-action@v2
    
    - name: Execute Gradle build
      run: ./gradlew build

Why use the gradle-build-action?

It is possible to directly invoke Gradle in your workflow, and the actions/setup-java@v3 action provides a simple way to cache Gradle dependencies.

However, the gradle-build-action offers a number of advantages over this approach:

• Easily run the build with different versions of Gradle using the gradle-version parameter. Gradle distributions are automatically downloaded and cached.
• More sophisticated and more efficient caching of Gradle User Home between invocations, compared to setup-java and most custom configurations using actions/cache. More details below.
• Detailed reporting of cache usage and cache configuration options allow you to optimize the use of the GitHub actions cache.
• Automatic capture of Build Scan® links from the build, making these easier to locate for workflow run.

The gradle-build-action is designed to provide these benefits with minimal configuration. These features work both when Gradle is executed via the gradle-build-action and for any Gradle execution in subsequent steps.

Use a specific Gradle version

The gradle-build-action can download and install a specified Gradle version, adding this installed version to the PATH. Downloaded Gradle versions are stored in the GitHub Actions cache, to avoid requiring downloading again later.

 - uses: gradle/gradle-build-action@v2
   with:
     gradle-version: 6.5

The gradle-version parameter can be set to any valid Gradle version.

Moreover, you can use the following aliases:

Alias	Selects
wrapper	The Gradle wrapper's version (default, useful for matrix builds)
current	The current stable release
release-candidate	The current release candidate if any, otherwise fallback to current
nightly	The latest nightly, fails if none.
release-nightly	The latest release nightly, fails if none.

This can be handy to automatically verify your build works with the latest release candidate of Gradle:

name: Test latest Gradle RC
on:
  schedule:
    - cron: 0 0 * * * # daily
jobs:
  gradle-rc:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v3
    - uses: actions/setup-java@v3
      with:
        distribution: temurin
        java-version: 11
    - uses: gradle/gradle-build-action@v2
      with:
        gradle-version: release-candidate
    - run: gradle build --dry-run # just test build configuration

Gradle Execution

If the action is configured with an arguments input, then Gradle will execute a Gradle build with the arguments provided.

If no arguments are provided, the action will not execute Gradle, but will still cache Gradle state and configure build-scan capture for all subsequent Gradle executions.

name: Run Gradle on PRs
on: pull_request
jobs:
  gradle:
    strategy:
      matrix:
        os: [ubuntu-latest, macos-latest, windows-latest]
    runs-on: ${{ matrix.os }}
    steps:
    - uses: actions/checkout@v3
    - uses: actions/setup-java@v3
      with:
        distribution: temurin
        java-version: 11
    
    - name: Setup and execute Gradle 'test' task
      uses: gradle/gradle-build-action@v2
      with:
        arguments: test

Multiple Gradle executions in the same Job

It is possible to configure multiple Gradle executions to run sequentially in the same job. The initial Action step will perform the Gradle setup.

- uses: gradle/gradle-build-action@v2
  with:
    arguments: assemble
- uses: gradle/gradle-build-action@v2
  with:
    arguments: check

Gradle command-line arguments

The arguments input can be used to pass arbitrary arguments to the gradle command line. Arguments can be supplied in a single line, or as a multi-line input.

Here are some valid examples:

arguments: build
arguments: check --scan
arguments: some arbitrary tasks
arguments: build -PgradleProperty=foo
arguments: |
    build
    --scan
    -PgradleProperty=foo
    -DsystemProperty=bar    

If you need to pass environment variables, use the GitHub Actions workflow syntax:

- uses: gradle/gradle-build-action@v2
  env:
    CI: true
  with:
    arguments: build

Gradle build located in a subdirectory

By default, the action will execute Gradle in the root directory of your project. Use the build-root-directory input to target a Gradle build in a subdirectory.

- uses: gradle/gradle-build-action@v2
  with:
    arguments: build
    build-root-directory: some/subdirectory

Using a specific Gradle executable

The action will first look for a Gradle wrapper script in the root directory of your project. If not found, gradle will be executed from the PATH. Use the gradle-executable input to execute using a specific Gradle installation.

 - uses: gradle/gradle-build-action@v2
   with:
     arguments: build
     gradle-executable: /path/to/installed/gradle

This mechanism can also be used to target a Gradle wrapper script that is located in a non-default location.

Caching build state between Jobs

The gradle-build-action will use the GitHub Actions cache to save and restore reusable state that may be speed up a subsequent build invocation. This includes most content that is downloaded from the internet as part of a build, as well as expensive to create content like compiled build scripts, transformed Jar files, etc.

The state that is cached includes:

• Any distributions downloaded to satisfy a gradle-version parameter ;
• A subset of the Gradle User Home directory, including downloaded dependencies, wrapper distributions, and the local build cache ;

To reduce the space required for caching, this action makes a best effort to reduce duplication in cache entries.

Disabling caching

Caching is enabled by default. You can disable caching for the action as follows:

cache-disabled: true

Using the cache read-only

By default, the gradle-build-action will only write to the cache from Jobs on the default (main/master) branch. Jobs on other branches will read entries from the cache but will not write updated entries. See Optimizing cache effectiveness for a more detailed explanation.

In some circumstances it makes sense to change this default, and to configure a workflow Job to read existing cache entries but not to write changes back.

You can configure read-only caching for the gradle-build-action as follows:

cache-read-only: true

You can also configure read-only caching only for certain branches:

# Only write to the cache for builds on the 'main' and 'release' branches. (Default is 'main' only.)
# Builds on other branches will only read existing entries from the cache.
cache-read-only: ${{ github.ref != 'refs/heads/main' && github.ref != 'refs/heads/release' }}

Incompatibility with other caching mechanisms

When using gradle-build-action we recommend that you avoid using other mechanisms to save and restore the Gradle User Home.

Specifically:

• Avoid using actions/cache configured to cache the Gradle User Home, as described in this example.
• Avoid using actions/setup-java with the cache: gradle option, as described here.

Using either of these mechanisms may interfere with the caching provided by this action. If you choose to use a different mechanism to save and restore the Gradle User Home, you should disable the caching provided by this action, as described above.

Cache debugging and analysis

Gradle User Home state will be restored from the cache during the first gradle-build-action step for any workflow job. This state will be saved back to the cache at the end of the job, after all Gradle executions have completed. A report of all cache entries restored and saved is printed to the Job Summary when saving the cache entries. This report can provide valuable insignt into how much cache space is being used.

It is possible to enable additional debug logging for cache operations. You do via the GRADLE_BUILD_ACTION_CACHE_DEBUG_ENABLED environment variable:

env:
  GRADLE_BUILD_ACTION_CACHE_DEBUG_ENABLED: true

Note that this setting will also prevent certain cache operations from running in parallel, further assisting with debugging.

Stopping the Gradle daemon

By default, the action will stop all running Gradle daemons in the post-action step, prior to saving the Gradle User Home state. This allows for any Gradle User Home cleanup to occur, and avoid file-locking issues on Windows.

If caching is unavailable or the cache is in read-only mode, the daemon will not be stopped and will continue running after the job is completed.

How Gradle User Home caching works

Properties of the GitHub Actions cache

The GitHub Actions cache has some properties that present problems for efficient caching of the Gradle User Home.

• Immutable entries: once a cache entry is written for a key, it cannot be overwritten or changed.
• Branch scope: cache entries written for a Git branch are not visible from actions running against different branches. Entries written for the default branch are visible to all. https://docs.github.com/en/actions/using-workflows/caching-dependencies-to-speed-up-workflows#restrictions-for-accessing-a-cache
• Restore keys: if no exact match is found, a set of partial keys can be provided that will match by cache key prefix. https://docs.github.com/en/actions/using-workflows/caching-dependencies-to-speed-up-workflows#matching-a-cache-key

Each of these properties has influenced the design and implementation of the caching in gradle-build-action, as described below.

Which content is cached

Using experiments and observations, we have attempted to identify which Gradle User Home content is worth saving and restoring between build invocations. We considered both the respective size of the content and the impact this content has on build times. As well as the obvious candidates like downloaded dependencies, we saw that compiled build scripts, transformed Jar files and other content can also have a significant impact.

In the end, we opted to save and restore as much content as is practical, including:

• caches/<version>/generated-gradle-jars: These files are generated on first use of a particular Gradle version, and are expensive to recreate
• caches/<version>/kotlin-dsl and caches/<version>/scripts: These are the compiled build scripts. The Kotlin ones in particular can benefit from caching.
• caches/modules-2: The downloaded dependencies
• caches/transforms-3: The results of artifact transforms
• caches/jars-9: Jar files that have been processed/instrumented by Gradle
• caches/build-cache-1: The local build cache

In certain cases a particular section of Gradle User Home will be too large to make caching effective. In these cases, particular subdirectories can be excluded from caching. See Exclude content from Gradle User Home cache.

Cache keys

The actual content of the Gradle User Home after a build is the result of many factors, including:

• Core Gradle build files (settngs.gradle[.kts], build.gradle[.kts], gradle.properties)
• Associated Gradle configuration files (gradle-wrapper.properties, dependencies.toml, etc)
• The entire content of buildSrc or any included builds that provide plugins.
• The entire content of the repository, in the case of the local build cache.
• The actual build command that was invoked, including system properties and environment variables.

For this reason, it's very difficult to create a cache key that will deterministically map to a saved Gradle User Home state. So instead of trying to reliably hash all of these inputs to generate a cache key, the Gradle User Home cache key is based on the currently executing Job and the current commit hash for the repository.

The Gradle User Home cache key is composed of:

• The current operating system (RUNNER_OS)
• The workflow name and Job ID
• A hash of the Job matrix parameters
• The git SHA for the latest commit

Specifically, the cache key is: ${cache-protocol}-gradle|${runner-os}|${workflow-name}-${job-id}[${hash-of-job-matrix}]-${git-sha}

As such, the cache key is likely to change on each subsequent run of GitHub actions. This allows the most recent state to always be available in the GitHub actions cache.

Finding a matching cache entry

In most cases, no exact match will exist for the cache key. Instead, the Gradle User Home will be restored for the closest matching cache entry, using a set of "restore keys". The entries will be matched with the following precedence:

• An exact match on OS, workflow, job, matrix and Git SHA
• The most recent entry saved for the same OS, workflow, job and matrix values
• The most recent entry saved for the same OS, workflow and job
• The most recent entry saved for the same OS

Due to branch scoping of cache entries, the above match will be first performed for entries from the same branch, and then for the default ('main') branch.

After the Job is complete, the current Gradle User Home state will be collected and written as a new cache entry with the complete cache key. Old entries will be expunged from the GitHub Actions cache on a least-recently-used basis.

Note that while effective, this mechanism is not inherently efficient. It requires the entire Gradle User Home directory to be stored separately for each branch, for every OS+Job+Matrix combination. In addition, a new cache entry to be written on every GitHub Actions run.

This inefficiency is effectively mitigated by Deduplication of Gradle User Home cache entries, and can be further optimized for a workflow using the techniques described in Optimizing cache effectiveness.

Deduplication of Gradle User Home cache entries

To reduce duplication between cache entries, certain artifacts in Gradle User Home are extracted and cached independently based on their identity. This allows each Gradle User Home cache entry to be relatively small, sharing common elements between them without duplication.

Artifacts that are cached independently include:

• Downloaded dependencies
• Downloaded wrapper distributions
• Generated Gradle API jars
• Downloaded Java Toolchains

For example, this means that all jobs executing a particular version of the Gradle wrapper will share a single common entry for this wrapper distribution and one for each of the generated Gradle API jars.

Optimizing cache effectiveness

Cache storage space for GitHub actions is limited, and writing new cache entries can trigger the deletion of existing entries. Eviction of shared cache entries can reduce cache effectiveness, slowing down your gradle-build-action steps.

There are a number of actions you can take if your cache use is less effective due to entry eviction.

At the end of a Job, the gradle-build-action will write a summary of the Gradle builds executed, together with a detailed report of the cache entries that were read and written during the Job. This report can provide valuable insights that may help to determine the right way to optimize the cache usage for your workflow.

Select which jobs should write to the cache

Consider a workflow that first runs a Job "compile-and-unit-test" to compile the code and run some basic unit tests, which is followed by a matrix of parallel "integration-test" jobs that each run a set of integration tests for the repository. Each "integration test" Job requires all of the dependencies required by "compile-and-unit-test", and possibly one or 2 additional dependencies.

By default, a new cache entry will be written on completion of each integration test job. If no additional dependencies were downloaded then this cache entry will share the "dependencies" entry with the "compile-and-unit-test" job, but if a single dependency was downloaded then an entire new "dependencies" entry would be written. (The gradle-build-action does not yet support a layered cache that could do this more efficiently). If each of these "integration-test" entries with their different "dependencies" entries is too large, then it could result in other important entries being evicted from the GitHub Actions cache.

There are some techniques that can be used to avoid/mitigate this issue:

• Configure the "integration-test" jobs with cache-read-only: true, meaning that the Job will use the entry written by the "compile-and-unit-test" job. This will avoid the overhead of cache entries for each of these jobs, at the expense of re-downloading any additional dependencies required by "integration-test".
• Add an additional step to the "compile-and-unit-test" job which downloads all dependencies required by the integration-test jobs but does not execute the tests. This will allow the "dependencies" entry for "compile-and-unit-test" to be shared among all cache entries for "integration-test". The resulting "integration-test" entries should be much smaller, reducing the potential for eviction.
• Combine the above 2 techniques, so that no cache entry is written by "integration-test" jobs, but all required dependencies are already present from the restored "compile-and-unit-test" entry.

Select which branches should write to the cache

GitHub cache entries are not shared between builds on different branches. This means that each PR branch will have it's own Gradle User Home cache, and will not benefit from cache entries written by other PR branches. An exception to this is that cache entries written in parent and upstream branches are visible to child branches, and cache entries for the default (master/main) branch can be read by actions invoked for any other branch.

By default, the gradle-build-action will only write to the cache for builds run on the default (master/main) branch. Jobs run on other branches will only read from the cache. In most cases, this is the desired behaviour, because Jobs run against other branches will benefit from the cache Gradle User Home from main, without writing private cache entries that could lead to evicting shared entries.

If you have other long-lived development branches that would benefit from writing to the cache, you can configure these by overriding the cache-read-only action parameter. See Using the caches read-only for more details.

Similarly, you could use cache-read-only for certain jobs in the workflow, and instead have these jobs reuse the cache content from upstream jobs.

Exclude content from Gradle User Home cache

As well as any wrapper distributions, the action will attempt to save and restore the caches and notifications directories from Gradle User Home.

Each build is different, and some builds produce more Gradle User Home content than others. Cache debugging can provide insight into which cache entries are the largest, and the contents to be cached can be fine tuned by including and excluding certain paths within Gradle User Home.

# Cache downloaded JDKs in addition to the default directories.
gradle-home-cache-includes: |
    caches
    notifications
    jdks    
# Exclude the local build-cache and keyrings from the directories cached.
gradle-home-cache-excludes: |
    caches/build-cache-1
    caches/keyrings    

You can specify any number of fixed paths or patterns to include or exclude. File pattern support is documented at https://docs.github.com/en/actions/learn-github-actions/workflow-syntax-for-github-actions#patterns-to-match-file-paths.

Remove unused files from Gradle User Home before saving to cache

The Gradle User Home directory has a tendency to grow over time. When you switch to a new Gradle wrapper version or upgrade a dependency version the old files are not automatically and immediately removed. While this can make sense in a local environment, in a GitHub Actions environment it can lead to ever-larger Gradle User Home cache entries being saved and restored.

In order to avoid this situation, the gradle-build-action supports the gradle-home-cache-cleanup parameter. When enabled, this feature will attempt to delete any files in the Gradle User Home that were not used by Gradle during the GitHub Actions workflow, prior to saving the Gradle User Home to the GitHub Actions cache.

Gradle Home cache cleanup is considered experimental and is disabled by default. You can enable this feature for the action as follows:

gradle-home-cache-cleanup: true

Build reporting

The gradle-build-action collects information about any Gradle executions that occur in a workflow, and reports these via a Job Summary, visible in the GitHub Actions UI. For each Gradle execution, details about the invocation are listed, together with a link to any Build Scan® published.

Generation of a Job Summary is enabled by default. If this is not desired, it can be disable as follows:

generate-job-summary: false

Note that the action collects information about Gradle invocations via an Initialization Script located at USER_HOME/.gradle/init.d/build-result-capture.init.gradle. If you are using init scripts for the Gradle Enterprise Gradle Plugin like scans-init.gradle or gradle-enterprise-init.gradle, you'll need to ensure these files are applied prior to build-result-capture.init.gradle. Since Gradle applies init scripts in alphabetical order, one way to ensure this is via file naming.

Build Scan® link as Step output

As well as reporting the Build Scan link in the Job Summary, the gradle-build-action action makes this link available as a Step output named build-scan-url.

You can then use that link in subsequent actions of your workflow. For example:

# .github/workflows/gradle-build-pr.yml
name: Run Gradle on PRs
on: pull_request
jobs:
  gradle:
    runs-on: ubuntu-latest
    steps:
    - name: Checkout project sources
      uses: actions/checkout@v3
    - name: Setup Gradle
      uses: gradle/gradle-build-action@v2
    - name: Run build with Gradle wrapper
      id: gradle
      run: ./gradlew build --scan
    - name: "Add Build Scan URL as PR comment"
      uses: actions/github-script@v5
      if: github.event_name == 'pull_request' && failure()
      with:
        github-token: ${{secrets.GITHUB_TOKEN}}
        script: |
          github.rest.issues.createComment({
            issue_number: context.issue.number,
            owner: context.repo.owner,
            repo: context.repo.repo,
            body: '❌ ${{ github.workflow }} failed: ${{ steps.gradle.outputs.build-scan-url }}'
          })          

Saving build outputs

By default, a GitHub Actions workflow using gradle-build-action will record the log output and any Build Scan links for your build, but any output files generated by the build will not be saved.

To save selected files from your build execution, you can use the core Upload-Artifact action. For example:

jobs:   
  gradle:
    runs-on: ubuntu-latest
    steps:
    - name: Checkout project sources
      uses: actions/checkout@v3
    - name: Setup Gradle
      uses: gradle/gradle-build-action@v2
    - name: Run build with Gradle wrapper
      run: ./gradlew build --scan
    - name: Upload build reports
      uses: actions/upload-artifact@v3
      with:
        name: build-reports
        path: build/reports/

Support for GitHub Enterprise Server (GHES)

You can use the gradle-build-action on GitHub Enterprise Server, and benefit from the improved integration with Gradle. Depending on the version of GHES you are running, certain features may be limited:

• Build Scan links are captured and displayed in the GitHub Actions UI
• Easily run your build with different versions of Gradle
• Save/restore of Gradle User Home (requires GHES v3.5+ : GitHub Actions cache was introduced in GHES 3.5)
• Support for GitHub Actions Job Summary (requires GHES 3.6+ : GitHub Actions Job Summary support was introduced in GHES 3.6). In earlier versions of GHES the build-results summary and caching report will be written to the workflow log, as part of the post-action step.

GitHub Dependency Graph support

The gradle-build-action has support for submitting a GitHub Dependency Graph snapshot via the GitHub Dependency Submission API.

The dependency graph snapshot is generated via integration with the GitHub Dependency Graph Gradle Plugin, and saved as a workflow artifact. The generated snapshot files can be submitted either in the same job, or in a subsequent job (in the same or a dependent workflow).

The generated dependency graph snapshot reports all of the dependencies that were resolved during a bulid execution, and is used by GitHub to generate Dependabot Alerts for vulnerable dependencies, as well as to populate the Dependency Graph insights view.

You enable GitHub Dependency Graph support by setting the dependency-graph action parameter. Valid values are:

Option	Behaviour
disabled	Do not generate a dependency graph for any build invocations. This is the default.
generate	Generate a dependency graph snapshot for each build invocation, saving as a workflow artifact.
generate-and-submit	As per generate, but any generated dependency graph snapshots will be submitted at the end of the job.
download-and-submit	Download any previously saved dependency graph snapshots, submitting them via the Dependency Submission API. This can be useful to collect all snapshots in a matrix of builds and submit them in one step.

Dependency Graph submission (but not generation) requires the contents: write permission, which may need to be explicitly enabled in the workflow file.

Example of a simple workflow that generates and submits a dependency graph:

name: Submit dependency graph
on:
  push:
  
permissions:
  contents: write

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v3
    - name: Setup Gradle to generate and submit dependency graphs
      uses: gradle/gradle-build-action@v2
      with:
        dependency-graph: generate-and-submit
    - name: Run a build, generating the dependency graph snapshot which will be submitted
      run: ./gradlew build

Filtering which Gradle Configurations contribute to the dependency graph

If you do not want to include every dependency configuration in every project in your build, you can limit the dependency extraction to a subset of these.

To restrict which Gradle subprojects contribute to the report, specify which projects to include via a regular expression. You can provide this value via the DEPENDENCY_GRAPH_INCLUDE_PROJECTS environment variable or system property.

To restrict which Gradle configurations contribute to the report, you can filter configurations by name using a regular expression. You can provide this value via the DEPENDENCY_GRAPH_INCLUDE_CONFIGURATIONS environment variable or system property.

Example of a simple workflow that limits the dependency graph to runtimeClasspath configuration and to exclude buildSrc dependencies:

name: Submit dependency graph
on:
  push:
  
permissions:
  contents: write

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v3
    - name: Setup Gradle to generate and submit dependency graphs
      uses: gradle/gradle-build-action@v2
      with:
        dependency-graph: generate-and-submit
    - name: Run a build, generating the dependency graph from 'runtimeClasspath' configurations
      run: ./gradlew build
      env:
        DEPENDENCY_GRAPH_INCLUDE_CONFIGURATIONS: runtimeClasspath
        DEPENDENCY_GRAPH_INCLUDE_PROJECTS: "^:(?!buildSrc).*"

Gradle version compatibility

The plugin should be compatible with all versions of Gradle >= 5.0, and has been tested against Gradle versions "5.6.4", "6.9.4", "7.0.2", "7.6.2", "8.0.2" and the current Gradle release.

The plugin is compatible with running Gradle with the configuration-cache enabled. However, this support is limited to Gradle "8.1.0" and later:

• With Gradle "8.0", the build should run successfully, but an empty dependency graph will be generated.
• With Gradle <= "7.6.4", the plugin will cause the build to fail with configuration-cache enabled.

To use this plugin with versions of Gradle older than "8.1.0", you'll need to invoke Gradle with the configuration-cache disabled.

Dependency snapshots generated for pull requests

This contents: write permission is not available for any workflow that is triggered by a pull request submitted from a forked repository, since it would permit a malicious pull request to make repository changes.

Because of this restriction, it is not possible to generate-and-submit a dependency graph generated for a pull-request that comes from a repository fork. In order to do so, 2 workflows will be required:

1. The first workflow runs directly against the pull request sources and will generate the dependency graph snapshot.
2. The second workflow is triggered on workflow_run of the first workflow, and will submit the previously saved dependency snapshots.

Note: when download-and-submit is used in a workflow triggered via workflow_run, the action will download snapshots saved in the triggering workflow.
