Summary

A backwards compatible extension of the IdeHook fuctionality that allow passing in multiple file paths in a comma separated list:

./gradlew spotlessApply -PspotlessIdeHook=path/to/file_a.md,path/to/file_b.md

What does this solve?

Our specific use-case is to allow efficient invocation in a pre-commit hook. This way we can simply pass in a list of staged files and fix them in a single call.

I can imagine this might also be useful for plugin development.

Changes

• Adjusted the IdeHook.java including it's State class to enable handling multiple files
• Added new testcases to verify the behaviour

Notes

• I decided to just not support the std in/out flag for multiple files to make it simpler
