Hi 👐! Need help with KMM SourceSets

I want to add configuration to the compile classpath of jvmMain. Previously for standard java source sets (main and test sourceSets) my code looked like this:

val sourceSets = project.extensions.getByType(JavaPluginExtension::class.java).sourceSets

val configAction: SourceSet.() -> Unit= {
  compileClasspath += myConfiguration
}
          
sourceSets.findByName(name)?.apply(configAction) ?: sourceSets.whenObjectAdded { obj -> if (obj.name == name) configAction.invoke(obj) }

How can I replicate this for KMM-sourceSets? I tried using KotlinMultiplatformExtension, but KotlinSourceSets won't let me add my configuration to the classpath

Thanks!

In a multiplatform project, a Kotlin source set doesn't have the designated compileClasspath configuration which is resolved to determine compilation dependencies because a source set can participate in multiple compilations.

But jvmMain source set usually participates only in one compilation. You can access that compilation and get its compileDependencyConfiguration configuration:

kotlin {
     jvm {
           compilations {
                val main by getting {
                     configurations.compileDependencyConfiguration += ...
                }

However, each source set has configurations where it can declare dependencies. You can get the name of the corresponding configuration using source set ...ConfigurationName properties:

kotlin {
     sourceSets {
        val jvmMain by getting {
            project.configurations[compileOnlyConfigurationName] += 
        }

Hi! Yes, thank you, that helped!
However, in Android Studio (2022.3.1, KMM plugin 0.6.1(223)-18) dependencies are not sync'd and are displayed in red 😭. The build succeeds
