• Create minimal diffs - disable on save actions like reformat source code or organize imports. If you feel the source code should be reformatted create a separate PR for this change.
• Provide JUnit tests for your changes and make sure your changes don't break any existing tests by runningmvn.
• Before you pushing a PR, runmvn (by itself), this runs the default goal, which contains all build checks.
