kotlinlang

Not sure if this is being tracked but seems `compileReleaseKotlin` on a library project always runs kapt which in turn generates  some wierd `Cl.java` class which then subsiquently puts the Javac out of date causing it to compile again.
```
:core:compileReleaseJavaWithJavac (Thread[Task worker Thread 3,5,main]) started.
:core:compileReleaseJavaWithJavac
file or directory '/Users/chris/Git/OwlrAndroid/core/src/release/java', not found
Executing task ':core:compileReleaseJavaWithJavac' (up-to-date check took 0.017 secs) due to:
  Input file /Users/chris/Git/OwlrAndroid/core/build/tmp/kapt/release/java_src/__gen/annotation/Cl.java has changed.
Destination for generated sources was modified by kapt. Previous value = /Users/chris/Git/OwlrAndroid/core/build/generated/source/apt/release
