Task :app:checkReleaseDuplicateClasses FAILED about react-native

I am also facing this issue.
Have you got any solution @kikikiswanto?

[kikikiswanto]

just check your project level build.gradle file and remove extra thing which on is not used...

for me solved with comment one line,
/android/build.gradle
buildscript {
ext {
buildToolsVersion = "31.0.0"
minSdkVersion = 21
compileSdkVersion = 33
targetSdkVersion = 33

    googlePlayServicesVersion = "+" // default: "+"
    //firebaseMessagingVersion = "+" // default: "21.1.0"

thanks @SantoshYadavSridix

I am using react native 0.71.12

[ailtonaires]

I have the same problem.

Execution failed for task ':app:checkDebugDuplicateClasses'.

A failure occurred while executing com.android.build.gradle.internal.tasks.CheckDuplicatesRunnable
Duplicate class com.google.firebase.Timestamp found in modules jetified-firebase-common-21.0.0-runtime (com.google.firebase:firebase-common:21.0.0) and jetified-firebase-firestore-24.4.5-runtime (com.google.firebase:firebase-firestore:24.4.5)

any solution?
