I’m using kotlin.copyClassesToJavaOutput = true and it works well in our setup, but it causes tests to run twice when using the gradle test runner

Please try setting a classesDir for the main and test source sets:

sourceSets.main.classesDir = "..."

This will make Gradle think there's only one classes directory and disregard the separate Kotlin one.

ok thanks. I actually have been setting

sourceSets.main.kotlin.outputDir = classesDir
        sourceSets.test.kotlin.outputDir = testClassesDir

(which doesn’t work)

and it does work when setting the deprecated properties

sourceSets.main.output.classesDir = classesDir
        sourceSets.test.output.classesDir = testClassesDir

[masc3d]

is it intentional that it only works with the deprecated ones? as it yields the warning Gradle now uses separate output directories for each JVM language, but this build assumes a single directory for all classes from a source set. This behaviour has been deprecated and is scheduled to be removed in Gradle 5.0

[masc3d]

as a sidenote I just managed to get rid of the warnings by using

sourceSets.main.output.classesDirs.setFrom(classesDir)
        sourceSets.test.output.classesDirs.setFrom(testClassesDir)

instead
