Incremental compilation with traits reproducer

This reproduces issue with Groovy traits and Gradle incremental compilation.

Steps to reproduce:

git clone git@github.com:asodja/groovy-traits-compilation-reproducer.git
run ./gradlew :lib:compileGroovy --no-build-cache
Change println("a") in MyTest.groovy to println("b")
run ./gradlew :lib:compileGroovy --no-build-cache again
See error

To resolve the issue run ./gradlew :lib:compileGroovy --no-build-cache --rerun-tasks

Exception thrown:

Classes hierarchy:

class MyTest extends MyTestBase implements WithPluginValidation { ... }

class MyTestBase { ... } has a dependency to MyTest inside a method

@SelfType(MyTestBase)
trait WithPluginValidation {
    final AllPluginsValidation allPlugins = new AllPluginsValidation(this)

    static class AllPluginsValidation {
        final MyTestBase base
        AllPluginsValidation(MyTestBase base) {
            this.base = base
        }
    }
