Sample project demonstrating bug with Kotlin compiler using in-process execution strategy.
Building the project with the default settings works fine:
./gradlew clean assembleDebugBuilding using in-process execution will fail:
export GRADLE_OPTS='-Dkotlin.compiler.execution.strategy="in-process"'
./gradlew clean assembleDebugStack trace:
e: java.lang.IllegalStateException: failed to analyze: java.lang.AssertionError: java.lang.ClassCastException: com.sun.tools.javac.api.JavacTrees cannot be cast to com.sun.source.util.Trees
