Anyone know how you set kotlinOptions (specifically freeCompilerArgs) for android targets? I must be missing something obvious, but android.compilations is just an empty array (which is also a bit weird and doesn’t match https://kotlinlang.org/docs/reference/building-mpp-with-gradle.html#default-project-layout) and using

targets.all {
        compilations.all {
            kotlinOptions {
                freeCompilerArgs = ["..."]
            }
        }
    }

does not work either (which kinda makes sense since the compilations array is empty).

Looks like the Android targets are not available until after the evaluation phase. Doing it after seemed to do the trick:

project.afterEvaluate {
    kotlin.targets.android.compilations.all {
        kotlinOptions {
            freeCompilerArgs = ["..."]
        }
    }
}

+1, some time ago also found that issue...

this is what I use, but not sure if it addresses your issue specifically:

tasks.withType<KotlinCompile> {
    kotlinOptions.jvmTarget = "1.8"
    kotlinOptions.freeCompilerArgs += "-Xuse-experimental=kotlinx.coroutines.ObsoleteCoroutinesApi"
}
