Ruoyun Huang created BEAM-6339:
----------------------------------
Summary: In certain cases, spotlessJava fails to work
Key: BEAM-6339
URL: https://issues.apache.org/jira/browse/BEAM-6339
Project: Beam
Issue Type: Improvement
Components: build-system
Reporter: Ruoyun Huang
Assignee: Ruoyun Huang
Encounter following error when certain criteria exists in new code:
> Task :beam-runners-google-cloud-dataflow-java:spotlessJava FAILED
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task
':beam-runners-google-cloud-dataflow-java:spotlessJava'.
> You have a misbehaving rule which can't make up its mind.
This means that spotlessCheck will fail even after spotlessApply has run.
This is a bug in a formatting rule, not Spotless itself, but Spotless can
work around this bug and generate helpful bug reports for the broken rule
if you add 'paddedCell()' to your build.gradle as such:
spotless {
format 'someFormat', {
...
paddedCell()
}
}
The next time you run spotlessCheck, it will put helpful bug reports into
'runners/google-cloud-dataflow-java/build/spotless-diagnose-java', and
spotlessApply
and spotlessCheck will be self-consistent from here on out.
