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-sources/9401/5

sourceSets {
   gen {
        java.srcDir "src/gen/java"
    }
}

But I stuck with the kotlin-dsl to add a new one. All I've got is:

java {
    sourceSets {

    }
}

Can anyone help here to

Answer 1

You should try the following:

java.sourceSets.create("src/gen/java")

Hope it's what you need!

Answer 2

The answer of @s1m0nw1 is correct to add a new sourceset. But to just add a new source-folder in an existing sourceset, this can be used:

java.sourceSets["main"].java {
    srcDir("src/gen/java")
}

Answer 3

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")
}

Answer 4

Worked for me on Gradle 4.10.2:

sourceSets.create("integrationTest") {
    java.srcDir("src/integrationTest/java")
    java.srcDir("build/generated/source/apt/integrationTest")
    resources.srcDir("src/integrationTest/resources")
}

Answer 5

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.
