Only thing I don't like about GitHub Actions so far is the YAML structure. e.g.

    name: master-pull-request
    on:
      pull_request:
        branches:
          - master
    jobs:
      test:
        name: run tests
        runs-on: ubuntu-18.04
        steps:
          - uses: actions/checkout@v1
          - name: Run gradle test
            run: |
              ./gradlew test

I much prefer Drone CI's YAML:

    kind: pipeline
    name: default
    steps:
      - name: run tests
        image: openjdk:8-jdk-slim # Docker images!
        commands:
        - ./gradlew test
