A modern programming language that makes developers happier.

kotlinlang

<@U6P03BM0W> Check the package `kotlin.coroutines.experimental` - that's where it is. Also it has `SinceKotlin("1.1")` restriction, so in case if you use -apiVersion 1.0 (most likely not), it may be hidden

I think that might be the problem.. I have some Gradle dependencies that are at Kotlin 1.0.3, I thought since they resolve to the declared 1.2.41 that it shouldn't be a problem... I guess Idea still hides it. I probably have to exclude Kotlin from the deps, is that the expected behavior?

You could check what is the effective version of kotlin-stdlib with gradle's dependencies task

And the resulting api version is shown in the kotlin facet of a project in the project structure dialog in Idea.
