Checkstyle integration

[delanym]

hi. Are there any plans for integration with https://checkstyle.sourceforge.io ?

In the short-term, Spotless only integrates with tools which can fix the problems they find. It is a formatter, not a linter. Long-term, we do have plans to support linters, at which point it might make sense to add checkstyle support. #1097 is the PR to watch.
