This is not strictly Kdsl related, but in #general this wasn't answered, so maybe someone here can help? Sorry for double posting, but I did wait a while 🙂

After update to kotlin 1.1.4, my gradle build (groovy based) fails with following Task with path 'copyMainKotlinClasses' not found in project. In build.gradle I have:

// groovy code should have access to kotlin classes for things like blablabla to work
tasks.compileGroovy.dependsOn 'copyMainKotlinClasses'
// and also for tests
tasks.compileTestGroovy.dependsOn 'copyTestKotlinClasses'

Gradle version: 4.0.1

What does copyMainKotlinClasses task? And why you need it?

[Czar]

@tapchicoma because the project I'm working on has Java, Groovy and Kotlin interlaced in the most peculiar way and without it Groovy classes cannot resolve Kotlin dependencies. This tasks ensures that Kotlin generated classes are available on the classpath before it compiles Groovy.

I heard that there is some changes where kotlin now puts class files, may check it later

[tapchicoma]

checked, indeed there is no copyMainKotlinClasses task anymore, but I see compiled classes in build/classes/kotlin folder. Maybe you don't need this dependsOn anymore?

[tapchicoma]

or depends on compileKotlin task

[tapchicoma]

check this line: https://github.com/JetBrains/kotlin/blob/a872b84785d9c101e3e93392003724800ff08802/libraries/tools/kotlin-gradle-plugin/src/main/kotlin/org/jetbrains/kotlin/gradle/plugin/KotlinPlugin.kt#L285

there was no check in 1.1.3 isSeparateClassesDirSupported

As I've said, without it Groovy code does not see Kotlin code. Depending on compileKotlin instead does not have any effect either.
