Android Studio 3.2 Canary 2 Kotlin runtime VerifyError: Rejecting class

Question

Hi I've just updated Android Studio to 3.2 canary 2 and my project compile fine but I have a runtime exception.

Here is the crash :

Is this a plugin bug, a Kotlin bug, or am I missing something? I'd prefer not go back to the previous version.

Answer 1

This is a bug with gradle version 3.2.0-alpha03

Reverting to 3.2.0-alpha02 in project's build.gradle did the trick for me.

Answer 2

Seems to be an issue with gradle plugin 3.2.0-alpha03 when using reflection in Kotlin:

java.lang.VerifyError Rejecting class kotlin.reflect.jvm.internal.KClassImpl that attempts to sub-class erroneous class kotlin.reflect.jvm.internal.KDeclarationContainerImpl.

Fix:

1. Revert gradle to alpha02 in build.gradle (Project)
2. Downgrade Android Studio to 3.2 Canary 2 to maintain alignment https://developer.android.com/studio/archive.html
