Firebase Duplicate Classes

Development Pipeline & Plugins

I just installed the “Firebase Features” plug-in and am now getting a Duplicate Classes build error. I have done about 40 successful builds before installing so it’s clearly related to the plug-in. I’ve tried deleting Intermediate folders, converting the project from Blueprint to C++ and rebuilding, changing Gradle version, updating Java and other fixes.

I have reached out to the developer but haven’t heard back yet and I need to deploy this within the next week (Authentication is the final thing I need to add) so any chance someone here can advise on how to fix this?

I feel like I understand the error itself, but the main solutions I’ve seen are to exclude one of the classes, but I don’t know which one to exclude and if by doing so if something that uses it will break.

Help? Lol

I’m now thinking this error is from the Convai plug-in not Firebase because the only reference I can find to playcore library is in the Convai XML file and it specifically implements com.google.android.play:core:1.9.0

Trying to directly update the implementation and see if it breaks anything. Will report back and hopefully, in the meantime, someone has some insight.

Perhaps me connecting to Firebase actually causes it to use that code and it finally flagged it? :person_shrugging:
