React Native: Execution failed for task ':app:checkDebugDuplicateClasses'

Issue

I am getting the next error appearing on running npx react-native run-android. It came out of nowhere - no changes have been committed.

Execution failed for task ':app:checkDebugDuplicateClasses'.
A failure occurred while executing com.android.build.gradle.internal.tasks.CheckDuplicatesRunnable

What I tried:

1. Follow again the installation steps on official react native documentation page: https://reactnative.dev/docs/environment-setup

    brew install node
    brew install watchman
    brew tap homebrew/cask-versions
    brew install --cask zulu11
   

2. Uninstall and install Android Studio

3. Set kotlinVersion = "1.8.0" in android/build.gradle:

    buildToolsVersion = "32.0.0"
    minSdkVersion = 21
    compileSdkVersion = 33
    targetSdkVersion = 33
    // here
    kotlinVersion = "1.8.0"
   

It looks like if I get rid of "react-native-inappbrowser-reborn": "^3.7.0" library the error is gone and the app launches successfully. But what if I need react-native-inappbrowser-reborn in my project?

Thank you mates in advance!

Solution

This is caused by the Kotlin plugin update. You can fix it easily by using configure below:

dependencies {
    implementation fileTree(dir: "libs", include: ["*.jar"])
    //noinspection GradleDynamicVersion
    implementation "com.facebook.react:react-native:+"  // From node_modules
    implementation 'com.android.support:multidex:2.0.1'
    implementation "androidx.swiperefreshlayout:swiperefreshlayout:1.0.0"

    // Add this line here
    implementation platform('org.jetbrains.kotlin:kotlin-bom:1.8.0')

    //...omit some code
}
