error: Execution failed for task ':app:mergeDebugNativeLibs'

Question

My react native app was running correctly, but suddenly I started getting error:

error 1: Execution failed for task ':react-native-webview:compileDebugKotlin'.

so for this in android/build.gradle I added kotlinVersion = "1.5.31" and also dependencies added classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.5.31".

After this I got the following error:

* What went wrong:
Execution failed for task ':app:mergeDebugNativeLibs'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade
   > More than one file was found with OS independent path 'lib/arm64-v8a/libfbjni.so'. If you are using jniLibs and CMake IMPORTED targets, see https://developer.android.com/studio/preview/features#automatic_packaging_of_prebuilt_dependencies_used_by_cmake

for this, inside android/app/build.gradle under android{...} I added:

packagingOptions {
    pickFirst 'lib/x86/libc++_shared.so'
    pickFirst 'lib/x86_64/libjsc.so'
    pickFirst 'lib/arm64-v8a/libjsc.so'
    pickFirst 'lib/arm64-v8a/libc++_shared.so'
    pickFirst 'lib/x86_64/libc++_shared.so'
    pickFirst 'lib/armeabi-v7a/libc++_shared.so'
    pickFirst 'lib/armeabi-v7a/libfbjni.so'
}

but even after this I am getting the same error again: More than one file was found with OS independent path 'lib/arm64-v8a/libfbjni.so'

Answer 1

Add following lines inside the android>build.gradle file -

allprojects {
repositories {
    ...
    exclusiveContent {
       // We get React Native's Android binaries exclusively through npm,
       // from a local Maven repo inside node_modules/react-native/.
       // (The use of exclusiveContent prevents looking elsewhere like Maven Central
       // and potentially getting a wrong version.)
       filter {
           includeGroup "com.facebook.react"
       }
       forRepository {
           maven {
               url "$rootDir/../node_modules/react-native/android"
           }
       }
   }
}
