I'm also experiencing this with the latest version.

I see there's a new setting "Enable kotlinx.coroutines packaging option" which aims to fix exactly this but it simply doesn't help.

Testing on a blank project with just admob

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':unityLibrary:mergeReleaseJavaResource'.

Hello Luis,

Thanks for reaching out.

This might be a Gradle cache issue. Can you check the following:

1. The environment you are running the build - Unity Editor Version, Gradle version and Android Gradle Plugin version.
2. Can you confirm the Remove property tag from GMA Android SDK is turned on. This can be found in Assets > Google Mobile Ads > Settings... > Android settings
3. Also is it possible to clean build with a clean gradle cache. This can be done by deleting the caches folder in gradle installation directory. On a Mac this can be found at: ~/.gradle/caches/

Regards,
Joshua

1) I tested in Unity versions 2022.3.13f1 and 2021.3.19f1, with Unity's built in gradle versions

https://docs.unity3d.com/Manual/android-gradle-overview.html

2)Tested with both new settings marked

3) Tried clearing Gradle cache (Windows) still no help

I managed to solve the issue though in Unity 2021 by manually putting this in launcherTemplate.gradle

packagingOptions {
pickFirst  'META-INF/kotlinx_coroutines_core.version'
}

I see that Google is attempting to do just that cuz there's the same snippet in Plugins/Android/GoogleMobileAdsPlugin.androidlib/packaging_options.gradle, but it's not working for some reason, even with the setting regarding this ticked.

With 2022 a new gradle error popped up:

FAILURE: Build failed with an exception.

* Where:
Settings file 'C:\Users\luis_\Documents\Unity Projects\Admob test\Library\Bee\Android\Prj\IL2CPP\Gradle\settings.gradle' line: 14

* What went wrong:
A problem occurred evaluating settings 'Gradle'.
> Could not find method dependencyResolutionManagement() for arguments [settings_2ctfxs0sy1p8yswwt8b52l3qh$_run_closure1@83924f7] on settings 'Gradle' of type org.gradle.initialization.DefaultSettings.

Hello Luis,


Just wanted to follow up and see if you're still having any issues with the Unity plugin.

If so, I would suggest going through our developer documentation on Build Unity for Android.

Let me know if you need anything else by replying to this email.


Thanks,
