Android Gradle Build: duplicate entry: META-INF/app_release.kotlin_module

I'm trying to build a release app via Android Studio > Generate Signed Bundle or APK > Android App Bundle > Release
However gradle fails with
: > Task :core:transformClassesWithMergeClassesForRelease FAILED
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':core:transformClassesWithMergeClassesForRelease'.
> 1 exception was raised by workers:
java.util.zip.ZipException: duplicate entry: META-INF/app_release.kotlin_module
In my build.gradle I've tried adding:
packagingOptions {
exclude 'META-INF/app_release.kotlin_module'
}
But it isn't making any difference whatsoever.
How do I fix this?
For extra context, it's a multi module project.
I have a core module, and an installed module which is declared in the core build.gradle with dynamicFeatures = [":installed"]
Thanks

Please make sure all your dependencies are api or implementation,
I have the flowing dependency grap.
meemo_sdk:
api project(":gvoice")
app project:
implementation project(":gvoice")
implementation project("meemo_sdk")
It complains "META-INF/gvoice_debug.kotlin_module" collision.
After change api to implementation, it works!

So I figured it out.
I pressed shift twice in Android studio (to open up the search everywhere dialog) and searched for app_release.kotlin_module
I saw two files, that were under two of my dependencies (which funnily enough were libraries that I had created!)
I opened up these library projects, and in the build.gradle file I had to add:
ext {
PUBLISH_GROUP_ID = 'com.companyname'
PUBLISH_ARTIFACT_ID = 'packagename'
}
android {
...
compileOptions {
kotlinOptions.freeCompilerArgs += ['-module-name', "$PUBLISH_GROUP_ID.$PUBLISH_ARTIFACT_ID"]
}
}
Rebuilt the library projects with new versions, used these new versions in my other project, and it started compiling :)

Build -> Clean Project Worked for me

I found the same issue comes randomly by using Android Studio 4.2.1 and Java8, I sorted out successfully by deleting .gradle file in the project (not the main one) every time I get the error.
Java version: JDK8221
Kotlin: 1.5.0
AndroidStudio: 4.2.1
Not the best solution but is a good workaround for now.

compileReleaseJavaWithJavaC failed for react native modules when building a release build

Task :react-native-device-info:compileReleaseJavaWithJavac FAILED
FAILURE: Build failed with an exception.
What went wrong:
Execution failed for task ':react-native-device-info:compileReleaseJavaWithJavac'.
java.io.FileNotFoundException: /workspace/eos-native/node_modules/react-native-device-info/android/build/intermediates/annotation_processor_list/release/annotationProcessors.json (No such file or directory)
The error makes sense , and the file is not there, but I have no idea why its not there? It is created when I run a debug version of the app and debug versions of my libraries, react-native-device-info, react-orientation-locker etc.. I've cleaned, gradle synched, rebuilt etc. but when trying to assemble or install a release build I get this error within seconds. What is causing the Java

I had the same problem in an android project (without react) when I added a library module.
After searching for a solution for quite some time, I finally deleted the .gradle directory in the project root folder.
This solved the problem for me.

update android gradle plugin to 3.3
update gradle to 4.10.3
fixed the issue for me.

Error in compiling ui dependency in android studio

Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.
com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/google/android/gms/internal/zzahl.class

In terminal execute in root project folder:
./gradlew clean
Try this!

The documentation says that.
Each version of FirebaseUI has dependency on a fixed version of these
libraries, defined as the variable firebase_version in
common/constants.gradle. If you are using any dependencies in your app
of the form compile 'com.google.firebase:firebase-:x.y.z' or compile
'com.google.android.gms:play-services-:x.y.z' you need to make sure
that you use the same version that your chosen version of FirebaseUI
requires.

java.util.zip.ZipException: duplicate entry: com/localytics/android/BuildConfig.class

I'm having this error when integrating Adobe Creative SDK. The problem seems to come from Localytics library inside the Creative SDK.
Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.
com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/localytics/android/BuildConfig.class
This seems to happen because we are also using Localytics in our project but I found out that the one in the Creative SDK is older version (Ver. 2) than the one in our project (Ver. 4)

You can use this command at the Android Studio Terminal:
1
./gradlew :app:dependencies
2
./gradlew clean (Android ---> Clean the Project)
3
./gradlew clean assembleDebug | ./gradlew clean:assembleDebug
Let me know if this works! I fixed my project or if you need something more clear.

Duplicate Dependency Error At Run Time

I added Parceler Dependency, in build.gradle.
dependencies {
// Parceler
compile 'org.parceler:parceler-api:1.0.4'
apt 'org.parceler:parceler:1.0.4'
}
When i build the project, the project builds successfully but at run time it's throwing the below error.
Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.
> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: org/parceler/Parceler$$Parcels$1.class
I tried ./gradlew clean command, i did invalidate and restart cache. I also update my android studio to 12.1 preview and gradle to 2.10, but still the same issue.
Any kind of help or suggestions would be appreciated.

It sounds like a duplication of classes between a library (or libraries) and the main project:
http://parceler.org/#avoiding_parcels_indexing

After going through the parceler.org doc, i solved this issue by setting parcelsIndex = false to each of the model classes.
Parceler will not write a Parceler$$Parcels mapping class if no indexable classes exist and the Parcels utiltiy class will fallback to looking up the generated class by name.
