React Native Android: Execution failed for task ':app:signReleaseBundle'. java.lang.NullPointerException (no error message)

Question

Problem

I am trying to build the app (React Native on Android) but it fails with this error:

Task :app:signReleaseBundle FAILED w: Detected multiple Kotlin daemon sessions at build/kotlin/sessions

FAILURE: Build failed with an exception.

• What went wrong: Execution failed for task ':app:signReleaseBundle'.

A failure occurred while executing com.android.build.gradle.internal.tasks.FinalizeBundleTask$BundleToolRunnable java.lang.NullPointerException (no error message)

What I tried so far

Basically everything from this thread, but nothing worked. Which was in short mainy deleting modules / gradle and re-installing / cleaning.

Code

Not really sure about what to share here. This is from my android/build.gradle file:

    kotlinVersion = "1.6.0"
    buildToolsVersion = "31.0.0"
    minSdkVersion = 23
    compileSdkVersion = 33
    targetSdkVersion = 33

EDIT: After running ./gradlew :app:bundle --info I got this additional information:

• What went wrong: Could not determine the dependencies of task ':app:mergeReleaseNativeLibs'.

Could not resolve all task dependencies for configuration ':app:releaseRuntimeClasspath'. Could not find any matches for app.notifee:core:+ as no versions of app.notifee:core are available. Searched in the following locations: - file:/home/p/Development/mein-zke-mobile-app/node_modules/react-native/android/app/notifee/core/maven-metadata.xml - file:/home/p/Development/mein-zke-mobile-app/node_modules/jsc-android/dist/app/notifee/core/maven-metadata.xml - https://repo.maven.apache.org/maven2/app/notifee/core/maven-metadata.xml - https://dl.google.com/dl/android/maven2/app/notifee/core/maven-metadata.xml - https://www.jitpack.io/app/notifee/core/maven-metadata.xml Required by: project :app > project :notifee_react-native

Googling let me to this thread, but the proposed workaround does not work unfortunately :-(

Answer 1

Add this to android/build.gradle

allprojects {
...
    repositories {
...
        maven {
            url "$rootDir/../node_modules/@notifee/react-native/android/libs"
        }
    }
}
