Building

The build script in the project root provides a convenient way to perform many local build tasks:

1. ./build will lint and compile typescript sources
2. ./build all will lint and compile typescript and run unit tests
3. ./build init-scripts will run the init-script integration tests
4. ./build act <act-commands> will run act after building local changes (see below)

Using act to run integ-test workflows locally

It's possible to run GitHub Actions workflows locally with https://nektosact.com/. Many of the test workflows from this repository can be run in this way, making it easier to test local changes without pushing to a branch.

This feature is most useful to run a single integ-test-* workflow. Avoid running ci-quick-test or other aggregating workflows unless you want to use your local machine as a heater!

Example running a single workflow: ./build act -W .github/workflows/integ-test-caching-config.yml

Example running a single job: ./build act -W .github/workflows/integ-test-caching-config.yml -j cache-disabled-pre-existing-gradle-home

Known issues:

• integ-test-cache-cleanup.yml fails because gradle is not installed on the runner. Should be fixed by #33.
• integ-test-detect-java-toolchains.yml fails when running on a linux/amd64 container, since the expected pre-installed JDKs are not present. Should be fixed by #89.
• act is not yet compatible with actions/upload-artifact@v4 (or related toolkit functions)
  • See https://github.com/nektos/act/pull/2224
• Workflows run by act cannot submit to the dependency-submission API, as no GITHUB_TOKEN is available by default.

Tips:

• Add the following lines to ~/.actrc:
  • --container-daemon-socket - : Prevents "error while creating mount source path", and yes that's a solitary dash at the end
  • --matrix os:ubuntu-latest : Avoids a lot of logging about unsupported runners being skipped
• Runners don't have java installed by default, so all workflows that run Gradle require a setup-java step.
