Android - Task :app:mergeDexRelease FAILED

Question

please consider that I'm not very familiar with Android development.

Trying to generate the Android signed bundle for my React Native app, I've stumbled upon the following error:

Task :app:mergeDexRelease FAILED
D8: Program type already present: com.horcrux.svg.Brush$BrushType
com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives:

Program type already present: com.horcrux.svg.Brush$BrushType

...

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:mergeDexRelease'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade
   > com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives:

     Program type already present: com.horcrux.svg.Brush$BrushType

• I'm aware that BrushType is a class from react-native-svg
• I've ran gradlew app:dependencies and found no module depending on Brush or anything related to com.horcrux.svg or react-native-svg
• Already tried cleaning project, deleting .iml files, invalidating Android Studio caches, rebuilding, reinstalling node_modules and so on
• Tried messing with build.gradle and gradle.properties with no luck
• I've read through this android guide on duplicate classes also with no luck

I understand that there are 2 or more dependencies utilizing com.horcrux.svg.Brush$BrushType but I can't find them. I imagine that once I find them, I could do

implementation(:my-library) {
  exclude ...
}

Correct?

gradle.properties

android.useAndroidX=true
android.enableJetifier=true

org.gradle.daemon=true
org.gradle.jvmargs=-Xmx2560m

android/app/build.gradle

dependencies {
    implementation project(':react-native-appearance')
    implementation fileTree(dir: "libs", include: ["*.jar"])
    implementation "com.facebook.react:react-native:+"  // From node_modules
    implementation project(':watermelondb')
    implementation project(':react-native-calendar-events')

    if (enableHermes) {
        def hermesPath = "../../node_modules/hermes-engine/android/";
        debugImplementation files(hermesPath + "hermes-debug.aar")
        releaseImplementation files(hermesPath + "hermes-release.aar")
    } else {
        implementation jscFlavor
    }
}

Thanks in advance.

EDIT:

Solved by adding:

    implementation(project(':react-native-jitsi-meet')) {
      ...
      exclude group: 'com.facebook.react',module:'react-native-svg'
      ...
    }

In my case it was react-native-jitsi-meet that was causing the conflicts, I had to find it via trial and error.

Answer 2

Resolved: I have two packages @react-native-masked-view/masked-view (from previous developer) and @react-native-community/masked-view. Just remove @react-native-masked-view/masked-view package and try build.
