so I have a Kotlin project using Gradle 6.2 with the Kotlin DSL. I want to add a second sourceset main2 and than use the internal modifier to mutually hide classes inbetween main and main2. So this is the expected folder structure:

src/main/kotlin
src/main2/kotlin
src/test/kotlin

I've come pretty far by add this to my build.gradle.kts

sourceSets {
    val mainSourceSet: SourceSet = sourceSets["main"]
    val testSourceSet: SourceSet = sourceSets["test"]

    val main2SourceSet: SourceSet = create("main2") {
        compileClasspath += mainSourceSet.output
        runtimeClasspath += mainSourceSet.output
    }

    mainSourceSet.compileClasspath += main2SourceSet.output
    mainSourceSet.runtimeClasspath += main2SourceSet.output
    testSourceSet.compileClasspath += main2SourceSet.output
    testSourceSet.runtimeClasspath += main2SourceSet.output
}

now
• code in main can see all the public classes from main2 but not the internal ones
• code in main2 can see all the public classes from main but not the internal ones
• code in test can see all the public and internal classes from main
• code in test can only see the public classes from main2
How do I make the internal classes from main2 accessible to test?

the closest thing I found needed it's own custom plugin 😐 but that was probably still Gradle 5 https://stackoverflow.com/a/59260030

I switched to using three modules.
