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

I wanted to add a source set with the name "test-integration" and the source directory src/test-integration/kotlin. I was able to accomplish that by combining the two pre-existing answers:

java.sourceSets.create("test-integration").java {
    srcDir("src/test-integration/kotlin")
}
