🔥 [🐛] Duplicate class com.google.firebase.iid.FirebaseInstanceIdReceiver found

[alexstroukov]

Issue

Android builds are suddenly failing with the error. No code has changed. Error happens in CI and locally, in previously successfully built branches

* What went wrong:
Execution failed for task ':app:checkDebugDuplicateClasses'.
> 1 exception was raised by workers:
  java.lang.RuntimeException: Duplicate class com.google.firebase.iid.FirebaseInstanceIdReceiver found in modules classes.jar (com.google.firebase:firebase-iid:21.0.1) and classes.jar (com.google.firebase:firebase-messaging:22.0.0)

The issue happens in version 10.0.0, upgrading to latest 11.5.0 and cleaning the android project before rebuild doesn't have any effect. The issue still happens.

Have you converted to AndroidX?

• my application is an AndroidX application?
• I am using android/gradle.settings jetifier=true for Android compatibility?
• I am using the NPM package jetifier for react-native compatibility?

I experienced something like this in the past after upgrading node packages. Looking at my command history, the solution was to run gradlew clean from within the android folder and also deleting the output folders android/app/build and android/.gradle.

cd android
./gradlew clean
rm -r app/build
rm -r .gradle

Worth a try I guess :)

@DoctorJohn thanks for your suggestion. Unfortunately the issue still remains. It is also happening in CI which is obviously a fresh environment

Root cause is in react-native-push-notifications. Update to 7.3.1 over there zo0r/react-native-push-notification#1992 (comment)

Technical explanation here #5293 (comment)

[nandorojo]

(Hiding my comment since I fixed it)

@mikehardy apologies for bumping this years later, but I'm getting this error now, presumably due to expo-notifications. However, I'm on the latest version of expo-notifications, so I'm not sure what to do...

The weird thign is, I'm only using app and auth in my app. I didn't install messaging or functions from RNFB.
