Android Problem Matchers

Adds common problem matchers for Android builds to GitHub Action workflows. Currently adds support for the following tools:

• Kotlin compiler
• Android Lint
• Gradle

This action only configures the problem matchers in order to be compatible with diverse Android workflows.

Inputs

No inputs are needed.

Outputs

No outputs are generated apart from configured problem matchers.

Example usage

In your workflow YAML file add this step:

    - name: Setup Android problem matchers
      uses: jonasb/android-problem-matchers-action@v1

Example full workflow definition:

name: Android CI
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v1
    - name: Setup JDK 1.8
      uses: actions/setup-java@v1
      with:
        java-version: 1.8
    - name: Setup Android problem matchers
      uses: jonasb/android-problem-matchers-action@v1
    - name: Build Android
      run: |
        ./gradlew build -PisCI=true        

In order for Android Lint problems (especially warnings) to show up in the logs and be detected, make these changes to app/build.gradle:

android {
  lintOptions {
    textReport project.hasProperty('isCI')
    textOutput 'stdout'
  }
}
