How can I turn

compileKotlin {
    kotlinOptions {
        freeCompilerArgs += "-Xuse-experimental=org.mylibrary.ExperimentalMarker"
    }
}

into the kotlin dsl? I'm trying to disable all the coroutine experimental warnings, I found

tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).all {
    kotlinOptions.freeCompilerArgs += ["-Xuse-experimental=kotlin.Experimental"]
}

in kotlin dsl, but it has a bunch of errors in the ide, for example it says "Classifier KotlinCompile does not have a companion object..."

I do

tasks {
	withType(KotlinCompile::class.java).all {
		kotlinOptions {
			jvmTarget = "1.8"
			freeCompilerArgs = listOf("-Xjsr305=strict")
		}
	}
}

but (captain obvious here) upgrading to kotlin 1.3 would allow to completely the need as coroutine are officially supported

Thank you! I'm on 1.3, but I'm trying to use some new coroutine stuff like channels and flow that are still marked as experimental.

So I put that in my gradle file at the top level scope, and in listOf I put "-Xuse-experimental=kotlinx.coroutines.flow.Flow", but the IDE still hightlights flow stuff in yellow and asks me to use the annotation

[StevieB]

freeCompilerArgs = listOf(
            "-Xuse-experimental=kotlin.Experimental",
            "-Xuse-experimental=kotlinx.coroutines.ExperimentalCoroutinesApi",
            "-Xuse-experimental=kotlin.ExperimentalUnsignedTypes",
            "-XXLanguage:+InlineClasses"

Is what I used before, might not be the latest variety though!

[StevieB]

Or maybe now

"-Xuse-experimental=kotlinx.coroutines.FlowPreview"

and for the channel things

"-Xuse-experimental=kotlinx.coroutines.ObsoleteCoroutinesApi"

[gildor]

This is a bit more idiomatic Kotlin DSL syntax:

withType<KotlinCompile> {}

@nk I mention it here https://kotlinlang.slack.com/archives/C0922A726/p1560260538220700. Unfortunately I havent filed an issue yet.
