I think this is a better version:

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).all {
    kotlinOptions {
        freeCompilerArgs += [
                '-Xuse-experimental=kotlinx.coroutines.ObsoleteCoroutinesApi',
                '-Xuse-experimental=kotlinx.coroutines.ExperimentalCoroutinesApi'
        ]
    }
}

The += adds more options (just in case you already have some elsewhere), and Experimental is for things like Dispatchers.Unconfined.
