Question

I have this warning all over the place polluting our build logs to the point where circleci is making me download our build logs because they are too long `This declaration is experimental and its usage should be marked with kotlinx coroutines ExperimentalCoroutinesApi ` Is there a way I can declare that we are using experimental coroutines api in the `build gradle` and thus get rid of all these warnings everywhere Or am I forced to go to every file and explicitly annotate it
