# A workflow run is made up of one or more jobs that can run sequentially or in parallel

    steps:
    # Checks-out your repository under $GITHUB_WORKSPACE, so your job can access it
    - uses: actions/checkout@v2

    # Runs a single command using the runners shell
    - name: Compile and run tests on robot code
      run: ./gradlew build

    # Runs a simulation to spot check crashes
    - name: Run simulation to check for runtime errors
      run: timeout 1m ./gradlew simulateJava 2>&1 | awk -v rc=0 '/The robot program quit unexpectedly/ { rc=1 } 1; END {exit rc}'
      # 1. Run simulation with 1 minute timeout
      # 2. Redirect stderr to stdout (just in case)
      # 3. Use awk to check for robot crash message and set the return code based on this. (Alternative to grep that doesn't filter the simulation output)
