I can't seem to be able to update dev15 and dev16, I have these repositories in place:

maven(url =  "<https://dl.bintray.com/kotlin/kotlin-eap/>")
jcenter()
google()

There's a table of the old and new artifacts here https://developer.android.com/jetpack/androidx/releases/compose#refactor

Thanks, just realised this.

Also remove the kotlin-eap maven url in your project level gradle script and update the gradle plugin to 1.4.0-rc

Yeah I did earlier. Thanks
