I'm using Android Studio 3.2 Canary 14 and am trying to migrate an existing project to use `AndroidX`. It sounds from <https://developer.android.com/topic/libraries/support-library/androidx-rn> that I have to have set `android.enableJetifier=true` (this was done automatically for me when selecting "Refactor to AndroidX.." option). I've also updated target API level to 28. Anyone else seeing this issue?

The above error occurs when I run "Clean". In general am getting multiple errors like following if a do gradle sync:
