How to add new sourceset with gradle kotlin-dsl

Question

I want to add a sourceset src/gen/java. With groovy this is rather easy and already described in https://discuss.gradle.org/t/how-to-use-gradle-with-generated-sourc

Answer 1

Worked for me on Gradle 4.10.2:

sourceSets.getByName("main") {
    java.srcDir("src/main/java")
    java.srcDir("src/main/kotlin")
}
sourceSets.getByName("test") {
    java.srcDir("src/test/java")
    java.srcDir("src/test/kotlin")
}

The codes above can also be used in subprojects block.
