kotlinlang

This change <https://github.com/JetBrains/kotlin/commit/5ce514bd42a8e8cb2afac99ea20bc359a4222951> introduces a regression that prevent us to generate the Dokka documentation for Kotlin code without using Java code since we were using `sourceDirs = files(subprojects.collect { project -&gt; project.sourceSets.main.kotlin.srcDirs })`. What can I use to get only the Kotlin source dirs ?

Sorry for that. What affects your build, though, is only that now the Java directories are added to the Kotlin directory set eagerly during configuration, not `afterEvaluate { ... }` as it was before.
I would suggest the following workaround:
```
sourceDirs = files(subprojects.collect { project -&gt; project.sourceSets.main.kotlin.srcDirs - project.sourceSets.main.java.srcDirs })
```
