Bug More than one file was found with OS independent path 'META-INF/annotation-experimental_release.kotl

Recently i had to upgrade a plugin. Here is where the issues started, since Android now requires you now to upload apps targetting android 31.

Some details:
- Unity 2021.1.28f1
- Android sdk 31
- Gradle 6.1.1 (version Unity supports)

Multiple plugins
- Facebook (15.1.0)
- Firebase Analytics and Messaging (10.3.0)
- Google Mobile Ads Plugin (v7.3.1)
- TheoPlayer (a plugin to show advertisement specifcally for Belgium)
- ConsentManager

The issue lies with Google Mobile Ads and Theoplayer. TheoPlayer requires package com.google.ads.interactivemedia.v3:interactivemedia:3.22.2 this has a file named META-INF/annotation-experimental_release.kotlin_module and the androidx.annotation:annotation-experimental:1.1.0@aar used by Google mobile also has this file, so i constantly get the error when building More than one file was found with OS independent path 'META-INF/annotation-experimental_release.kotlin_module'.

Trying to exclude this file has no effect. I have no idea how to continue, googeling has not helped me neither. Anybody here with more android native coding experience who can help me further? I have attached our gradle file to this post.

I have tried

• excluding one of the 2 packages makes the build succeed, but ofcourse i am missing libraries then so functionality is broken
• using different version of packages but no success
• tried upgrading to Unity 2022.2 but nothing works there anyway

I don't know why excluding doesn't work. Does this have to do with the location of the duplicate files being in External Libraries?

P.S. I have exported to android studio and fixing it in android studio. This error comes from within android studio environment.

 

did you try :
exclude 'META-INF/annotation-experimental_release.kotlin_module'
or
pickFirst 'META-INF/annotation-experimental_release.kotlin_module'
or
merge 'META-INF/annotation-experimental_release.kotlin_module'
in the packagingOptions ?

 

Yes, none of those work.

 

Just searched on google and the solution found here https://socket.dev/npm/package/com.azerion.ads (end of the page) is to exclude the file.
Could you share the error you get after excluding the "META-INF/*.kotlin_module" ?

 

After adding the exclude exclude("META-INF/*.kotlin_module") i get the same error.....Somehow the exclude does not work.

Just to be 100% correct i added the exclude like you said in this gradle file



Like this

 

Following the link you gave you i learned about the launchertemplate.Gradle file in unity, if i add the exclude option there i actually have a working build. Thank you so much for helping!

 

launchertemplate.gradle is much more simpler than exporting an android project

 

Link doesnt open. Could you please provide solution here?
