Duplicate class caused by proto libraries clash when using both Firebase Performance Monitoring and Stripe SDK

[Milszym]

Summary

I am encountering Duplicate class gradle issue during :app:checkDebugDuplicateClasses and :app:mergeDebugJavaResource gradle tasks when using the Firebase Performance Monitoring library. It's caused by the clash of these two transitive dependencies.

• com.google.firebase:protolite-well-known-types:17.1.1 - existing in com.google.firebase:firebase-perf-ktx dependency
• com.google.protobuf:protobuf-java-util:3.11.4 - used by Stripe Terminal Beta SDK com.stripe:stripeterminal:2.0.0-b3
  Both libraries contains same classes like e.g.: class com.google.protobuf.AbstractMessageLite

A part of task failure message:

FAILURE: Build completed with 2 failures.

1: Task failed with an exception.

Part of the dependency tree generated after running :app:dependencies gradle task:

Stripe
+--- com.google.protobuf:protobuf-java-util:3.11.4
     |    +--- com.google.protobuf:protobuf-java:3.11.4
Firebase Performance Monitoring
+--- com.google.firebase:protolite-well-known-types:17.1.1
|    |    |    \--- com.google.protobuf:protobuf-javalite:3.14.0
|    |    +--- com.google.protobuf:protobuf-javalite:3.14.0

How can I approach this issue? I would like to use both Stripe and Firebase Performance Monitoring. I also don't want to exclude any of these protobuf dependencies, since it can cause some unpredictable runtime crashes, because of the lack of dependencies. Do you have any solution for this matter?

Code to reproduce

Here is a minimal repository to reproduce the issue:

Please just build and run the project to see the failure which I have described above.

Android version

SDK 24+ (7.0+)

Impacted devices (Android devices or readers)

All devices - it's happening during gradle task

SDK version

2.0.0-b3

Thanks for the feedback and the example!

We know it's frustrating for all of the folks that are using Firebase.  There's a project we've been working on to work around this issue Dan filed:

protocolbuffers/protobuf#8104

We don't have an ETA for the fix yet as the scope of the fix has taken a few months and there's quite a bit left to do, but we'll update the ticket when a fix is out.

Any work on this? The above linked issues was closed a few weeks ago, and the exclusion solution it describes is not working.

Appreciate your patience on this @bkinter. A fix will be available in our next release; currently scheduled for early next week.
