Gradle Android Scala Plugin fails due to trace files in generated source directory by Xtend in a multi language project

[celestialmachines]

Hi, there is an issue when compiling multi language android projects where the scala zinc compiler tries to compile non scala stuff which fails.

The plugin seems to work with all JVM languages I have used in a sample project except for xtend which creates binary trace files on which the zinc compiler fails.

It would be nice if there would be an option to prevent zinc from compiling the whole project, ie compile only scala.

The work around was to add this to my gradle build file so that it would invoke the standalone ant task thus compile only scala:

tasks.withType(ScalaCompile) {
scalaCompileOptions.useAnt = true
}

Feel free to request for more information if needed.
