lazy bug report: I had a query `SomefooQuery` with generated Kotlin classes. I renamed it to `SomeFooQuery`, and `compileKotlin` failed with `Redeclaration: SomeFooQuery` and `Redeclaration: SomefooQuery` errors. Seems like the lowercase file was kept and shouldn’t, `--rerun-tasks` fixed the issue

This is super weird, the first thing the GraphQL compiler is doing is removing the whole output directory...

Also shouldn't the Kotlin compiler be case sensitive and allow both `SomefooQuery` and `SomeFooQuery` ?

Could it be some weird incremental Kotlin compiler issue on MacOS case insensitive filesystem?

I've been hit by this recently: <https://youtrack.jetbrains.com/issue/KT-48797>

I can’t reproduce it when renaming a regular class in a similar fashion. But kapt runs on that module too, let me try a simpler one

Yeah it doesn’t happen just when I rename a class from `Somefoo` to `SomeFoo`, even if it’s in the same module that generates apollo classes in our project

Mmm I can reproduce renaming a regular class/file.

I think incremental compilation + MacOS case insensitive filesystem aren't really friends

I'll try to make a reproducer for Youtrack
