IllegalStateException during incremental annotation processing

Hi! My build is completely broken after specific commit and I have no idea why.

I have following exception in my build logs:

I’m using kotlin 1.3.50, gradle 5.6.2 и android gradle plugin 3.5.0. I tried to use gradle --debug flag and also kapt.verbose=true in gradle.properties file which did not tell me anything useful.

Another strange thing is this error occurred only on my teamcity server, but I can build my app perfectly fine from my computer.

Is someone know what may cause this exception?

In case someone gets this error - problem was after renaming file in Android Studio (DeliveryDTO -> DeliveryDto) both files gets somehow pushed to repository. My OS has case-insensitive file system, so only one file stays after pull and so build works perfectly fine. But file system on my CI server is case-sensitive and because of those two files build was failing with mentioned error.

Had similar issue. Check for Java and Kotlin classes with similar names.
