After 1.4 update our build started failing with

Caused by: java.lang.IllegalStateException: Unexpected non-class file: META-INF/versions/9/kotlin/reflect/jvm/internal/impl/serialization/deserialization/builtins/BuiltInsResourceLoader.class

Any ideas people what could be the cause?

Same thing. I’m seeing FirebasePerformancePlugin classes on my build output logs. Do you use FirebasePerformance? maybe this could be related to it.

Yes, we use firebase performance
