I've tried to update my Android project to Kotlin 1.4.0, since it's now oficially stable, and after update I've encountered a problem. I will not post the entire stack here, since it's very long, but the mot top part of it looks like this:

...
> Task :app:transformClassesWithFirebasePerformancePluginForDebug
java.lang.ClassNotFoundException: javax.mail.internet.MimeBodyPart
> Task :app:mergeDebugJavaResource
> Task :app:dexBuilderDebug FAILED
org.gradle.workers.WorkerExecutionException: There was a failure while executing work items
...

Looking for a cause, lower in the stack, I've found this:

...
Caused by: org.gradle.tooling.BuildException: Failed to process: 
/bitrise/src/app/build/intermediates/transforms/FirebasePerformancePlugin/debug/0, 
/bitrise/src/app/build/intermediates/transforms/FirebasePerformancePlugin/debug/1,
/bitrise/src/app/build/intermediates/transforms/FirebasePerformancePlugin/debug/2
...

Which directs me to the conclusion, that Firebase Performance library cannot be build correctly. I'm using Firebase Performance version 19.0.8 with gradle classpath plugin version 1.3.1. I have not changed it for a while, and reverting to earlier versions does not resolve the issue. The last error registered on stack is this:

Caused by: com.android.builder.dexing.DexArchiveBuilderException: Error while dexing.
    at com.android.builder.dexing.D8DexArchiveBuilder.getExceptionToRethrow(D8DexArchiveBuilder.java:151)
    at com.android.builder.dexing.D8DexArchiveBuilder.convert(D8DexArchiveBuilder.java:118)
    at com.android.build.gradle.internal.dexing.DexWorkActionKt.process(DexWorkAction.kt:194)
    ... 33 more
Caused by: java.lang.IllegalStateException: Unexpected non-class file: META-INF/versions/9/kotlin/reflect/jvm/internal/impl/serialization/deserialization/builtins/BuiltInsResourceLoader.class

I've determined, that removing Firebase Performance library and reverting back to Kotlin 1.3.71 resolves the problem, but I'd like to keep them both for future of the project, so I'm looking for other solution.

Why is this build failing? Is it Kotlin's 1.4.0 fault, or is there something wrong with dependencies? Can this issue be solved without reverting to previous Kotlin version?
