Gradle question, I think @Adam S might be the best person to answer. Inside a gradle plugin task, how do I get the source sets? Specifically, I am trying to get a handle to the "test" sourceset. At the moment I am looking for the JavaPluginExtension, and getting it from that, but this fails for android. Follow up question - when you have a layout like say src/main/java and src/main/kotlin and src/main/scala is "main" the sourceset, or is java kotlin scala the sourcesets?

[Emil Kantis]

They're available through the Kotlin extension.

// Configure Kotlin multiplatform projects
      project.pluginManager.withPlugin(KOTLIN_MULTIPLATFORM_PLUGIN) {
         project.extensions.configure<KotlinMultiplatformExtension> {
            sourceSets.filter { it.name.contains("test", ignoreCase = true) }

java, kotlin and scala would be the soucesets in your example was wrong.. oops 🙈

[sam]

is multiplatform there for android ?

[Emil Kantis]

Isn't Android just a regular JVM target?

[Adam S]

try taking a look at how Dokka Gradle plugin gets the source sets

JavaAdapter.kt is much more simple than KotlinAdapter.kt, but the principle should be the same

[Adam S]

the KotlinAdapter does a bunch of confusing stuff to be Configuration Cache compliant, but what Emil wrote is basically the same

[Adam S]

when you have a layout like say src/main/java and src/main/kotlin and src/main/scala is "main" the sourceset, or is java kotlin scala the sourcesets

a org.gradle.api.tasks.SourceSet is either main or test (or something else, because users can add their own custom SourceSets), and each SourceSet has 1+ source directories like src/main/kotlin

[LeoColman]

Android is a really weird JVM target. But yes, anything compiled to JVM should work on Android

[LeoColman]

@sam Yes, MPP is there for Android.

People develop apps having Common + IOS/Android and split the artifact for both platforms

[LeoColman]

We don't need to fully support MPP for it yet, as we don't really support Android officially. JVM versions should be fine as long as the JDK version is compatible (use 8 and you're find. Above this I'm not 100% sure)

This has been helpful. I'm still stuck though.
So I can get the

KotlinProjectExtension

and in there find the test sourceset. But this returns a KotlinSourceSet not a SourceSet . The regular SourceSet type that comes from the JavaBasePlugin has a runtimeClasspath option which is a file tree of all the compiled files. Trying to find the same thing but for Android projects.

[sam]

Ok so I have it working for android.
But it's hacky, I have to add this "tmp kotlin classes folder" to the runtime classpath manually.

val classesDir = project.layout.buildDirectory.get().asFile.toPath().resolve("tmp/kotlin-classes/releaseUnitTest")
val runtimeClasspath = project.configurations["releaseUnitTestRuntimeClasspath"]
val classpathWithTests = runtimeClasspath.plus(fileCollectionFactory.fixed(classesDir.toFile()))

I wonder if there's a way to make not use hard coded strings
