Kotlin.compiler.incremental doesn't support java-kotlin mixin project

when kotlin.compiler.incremental set to true, all classes import from java code will be ‘Unresolved reference’ during compile(Failed to execute goal org.jetbrains.kotlin:kotlin-maven-plugin:1.2.71:compile (compile) …)

if set it to false, everything is ok

Can you please create an issue at http://kotl.in/issue with a sample project that demonstrates the problem? Thank you.
