kotlinlang

I'm trying to build an Android Kotlin library with Gradle, but can't manage to produce a sources jar that includes my Kotlin sources. My sources are in `src/main/kotlin` (though using `src/main/java` doesn't change anything). The package structure is included, but only empty folders. I tried adding an include spec to my Jar task like this:

```
task androidSourcesJar(type: Jar) {
  classifier = 'sources'
  from android.sourceSets.main.java.sourceFiles
  include "**/*"
}
```

but that didn't help either. Does anyone have an idea what I'm doing wrong?
