> See reproducer here: https://github.com/asodja/groovy-traits-compilation-reproducer
> This reproduces issue with Groovy traits and Gradle incremental compilation.
> Steps to reproduce:
> 1. git clone git@github.com:asodja/groovy-traits-compilation-reproducer.git
> 2. run `./gradlew :lib:compileGroovy --no-build-cache`
> 3. Change `println("a")` in MyTest.groovy to `println("b")`
> 4. run `./gradlew :lib:compileGroovy --no-build-cache` again
> 5. See error
> To resolve the issue run `./gradlew :lib:compileGroovy --no-build-cache --rerun-tasks`
