Building Java-based microservices as part of a GitHub Action

I recently migrated all c14r builds from Azure DevOps to GitHub Actions.
The migration went smoothly. Here is a snippet:

build-dexter:
    name: Static Code Analysis for Dexter Microservice
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
        with:
          fetch-depth: 0
      - name: Set up JDK 11
        uses: actions/setup-java@v1
        with:
          java-version: 11
      - name: Cache SonarCloud packages
        uses: actions/cache@v1
        with:
          path: ~/.sonar/cache
          key: ${{ runner.os }}-sonar
          restore-keys: ${{ runner.os }}-sonar
      - name: Cache Maven packages
        uses: actions/cache@v1
        with:
          path: ~/.m2
          key: ${{ runner.os }}-m2-${{ hashFiles('**/dexter/pom.xml') }}
          restore-keys: ${{ runner.os }}-m2
      - name: Build and analyze
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          SONAR_TOKEN: ${{ secrets.DEXTER_SONAR_TOKEN }}
        run: cd dexter && mvn -B verify org.sonarsource.scanner.maven:sonar-maven-plugin:sonar

Pretty standard. The action does build the code on push and on a pull request, providing code quality metrics based on sonar insights and triggering all unit and integration tests. The full workflow is available here.
