Kotlinx.coroutines: 1.0.1 - Error while building Android

[ScottPierce]

This build error goes away when using 1.0.0. When switching to 1.0.1, we see this exception when building when using multiplatform project. Initially builds were succeeding and we were seeing crazy crashes at runtime, but eventually this build exception started happening:

kotlinx-coroutines-io version that you were using does not seem compatible with 1.0.1. Please try to update to version 0.1.0-beta-2

[ScottPierce]

I'm not specifying this the the kotlinx-coroutines-io dependency anywhere. It must be transitively pulled in through ktor.

The new ktor beta-4 release seems to have resolved this.

[Kanunnikoff]

@ScottPierce Good afternoon. Thank you very much! Had that problem too, and your direction (ktor) helped me.
