GitHub switched their MacOS runners to ARM, which makes the Android emulator fail to start. Since we introduced the CI workflow, GitHub upgraded the Ubuntu runners as well, now supporting hardware acceleration. This means we no longer need MacOS. The Ubuntu runner is also about 2 times faster.
- Run Checkstyle with gradle to make it easier for users
- No longer needs different configuration for new code
- Exclude current violations
- Fix some violations that somehow couldn't be specified in the exclusion file
- Print SpotBugs/Lint/Checkstly violations in GitHub format
- Then the CI run gets annotated on the web UI
