If use kotlin with groovy (http://kotlinlang.org/docs/reference/using-gradle.html)
groovy plugin deletes some kotlin .class files from build/classes
so it makes impossible to mix groovy with kotlin cause groovy plugin ignores source sets
Question: is it possible to configure groovy plugin to keep files in build/classes intact ?
p.s: kotlin plugin invokes: compileKotlin compileJava - up to date ------------------------------------ compileGroovy - deletes some Kotlin .classes - compilation error as a consequence since ClassNotFoundException happens
