Bug Error related to Levelplay Update:2 files found with path 'META-INF/kotlinx_coroutines_core.version'

Hello, I use unity levelplay for displaying my ads, I had created a unity game that used Ironsource and Unity Ads adapters and build and published it, no problem at first. Then however, I wanted to upgrade to the new version of the ironsource and unity ads adapters and on top integrate the google ad adapter, in hopes of increasing my ad revenue. In order to upgrade to the newer versions , I deleted my entire Ironsource folder (under "Assets/Ironsource") and then installed the adapters via the Levelplay integration manager (under "Ads Mediation/Integration Manager"). However, after reimporting everything and trying to build my game now, there is an error and the build failed. When I opened the Editor.log it said the following message:


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

A failure occurred while executing com.android.build.gradle.internal.tasks.MergeJavaResWorkAction 2 files found with path 'META-INF/kotlinx_coroutines_core.version' from inputs:

• I:\TitanCameramanRunSkibidi\Library\Bee\Android\Prj\IL2CPP\Gradle\unityLibrary\libs\org.jetbrains.kotlinx.kotlinx-coroutines-core-1.7.1.jar

This could theoretically also have something to do with the fact that when I tried to resolve under "Assets/Mobile Dependency Resolver/Android Resolver/Resolve", the resolution kept failing at first, sending following messages into the Editor.log file: "Failed to fetch the following dependencies: org.jetbrains.kotlin:kotlin-bom:1.8.10"

I have been trying to fix this for 2 days now, but can't seem to find any solution, therefore help would be more than very much appreciated, thanks in advance.

 

I am getting the same error "Failed to fetch the following dependencies: org.jetbrains.kotlin:kotlin-bom:1.8.10" when resolving andriod dependency using "Assets/Mobile Dependency Resolver/Android Resolver/Resolve"

unity editor version: 2021.3.7f1
gradle version: built-in (which came with unity editor)
levelplay sdk: IronSource_IntegrationManager_v7.5.1
admob adopter version: 4.3.54.0
unity ads adopter version: 4.3.36.2

 

I have the same "Failed to fetch the following dependencies: org.jetbrains.kotlin:kotlin-bom:1.8.10" error.
I also have some more information: the problem started with LevelPlay sdk "IronSource_IntegrationManager_v7.3.1.1".
And the problem happens when you have also IronSource and OneSignal in the project.
This is a sample project where the problem is easily triggerable by resolving android dependencies (https://drive.google.com/file/d/1NSrrrQXkPfqJNRZnMPuvel2LVS7ukZ_B/view?usp=drive_link)

We are using Unity 2021.3.28f1 with the built-in JDK, SDK, NDK and gradle versions.

These are the other things in the project that are triggering the problem:

• IronSource 7.3.1.1 or higher
• IronSource adapter - UnityAds 4.3.36.0 or higher
• OneSignal 3.0.9 or higher (EDIT: OneSignal 3.0.5 or higher)
• External Dependency Manager for Unity 1.2.175 or higher

I'm looking for a solution since 2 months but I haven't managed to fix it yet!

NOTE: I opened a ticket to IronSource, the ticket is #00352919, but they only replied asking me trying to update gradle. I don't know if it's the only solution, but in case, it would be great to know which version is the suggested one for the fix.

 

I also have OneSignal v 3.0.5.

 

Ok, I'll update the info above (specifing OneSignal 3.0.5 or higher).
I'm pretty sure we have the same problem so. Let's see if someone from Unity can help us.

 

Just a quick update: I have just downloaded gradle-8.3 (latest) and set it in the Unity path.
The resolution still fail with the same error.

 

I tried with unity ads and ironsource ads adopter but without adding admob adopter --> under "Ads Mediation/Integration Manager") and it works.

So I think admob adopter is creating a problem.Can you do the same and verify it?

 

Mmm... this is very strange!
In the test project I linked in the message above, it's failing with only IronSource, OneSignal and UnityAds.

However I've just tried deleting AdMob and it is still failing to me.
Can you please download the test project above and tell me if it works for you?

 

Hi, thanks for the answer:
1. I am using Unity Editor version 2022.2.9f1
2. I am using the built-in gradle version
3. I am basically using all the newest SDK and adapter versions:
a) My ironSource levelplay SDK version is 7.5.1
b) My UnityAds adapter version is 4.3.36.2
c) My Google(AdMob and Ad Manager) adapter version is 4.3.54.0
4. I uploaded my project to google drive and this is the link: https://drive.google.com/drive/folders/13MF_9xVd9eFpchhmi9e2a2kKZpN6YLVB?usp=sharing (I have changed the values of my appKeys and disabled my custom keystore for privacy reasons so that no everyone can see them by the way, though this doesn't affect the error.)

 

I tried your provided project and it is working fine. i also generated apk file with it. I used unity editor 2021.3.7f1

 

I have just retried, and I have errors.
So, should we conclude that it is related in some way to the environment where to dependencies resolution is running? If so, what settings should we check on our machines?

It seems really strange to me honestly. I would expect it depends on Unity version, not on the env.

 

Same problem, did you solve it?

 

same error for applovin and airbridge io with appsflyer with facebook sdk makes this issue for me

UnityEngine.GUIUtilityrocessEvent (int,intptr,bool&)

 

Haven't solved it yet.
I'm also trying to update the whole project to Unity 2022.3.10f1 but it does not help, same

Resolution failed

Failed to fetch the following dependencies:
org.jetbrains.kotlin:kotlin-bom:1.8.10

error when trying to resolve Android dependencies.

And, even without updating the UnityAds to the latest version, with Unity 2022.3.10 the same build error reported above appear.

@yunanhou, any news about these topics (dependencies resolution and build error)?

 

Same problem here with Unity 2022.3.10 and also tested with Unity 2022.3.4.

Edit: Fixed by deleting org.jetbrains.kotlinx.kotlinx-coroutines-core-jvm-1.7.1.jar .......

 

It fixed the build but I guess you will have problem with some plugin that actually has that package as a dependency.
Or did you find anything else that justify the .jar deletion?

 

Yes it's just a temporary solution to ship my app as I don't have the possibility to wait for an Unity official fix. I tested every part of my app and no crash so far... but I don't like being on the edge like that but it seems org.jetbrains.kotlinx.kotlinx-coroutines-core-jvm-1.7.1.jar is only for Unity (java virtual machine) ...

 

I tried the same and my app crash on startup because the OneSignal initialization is failing.
I guess you don't have OneSignal, am I right?

 

:S Yes I just use Admob (without OneSignal and IronSource) ...

 

It's nice to hear that someone has fixed the error. But how do you delete org.jetbrains.kotlinx.kotlinx-coroutines-core-jvm-1.7.1.jar? I tried deleting it but then it reappeared on its own

 

I've been getting the same error when running the Android Resolver:

Resolution failed

Failed to fetch the following dependencies:
org.jetbrains.kotlin:kotlin-bom:1.8.10

On Unity 2021.3.27.

Also tried to delete the file but I'm guessing it keeps getting regenerated by the Android Resolver? Not sure just yet.

 

To delete that file you have to disable the automatic resolution dependencies on build and run it manually. But it's not an "official workaround".
If you have OneSignal, for example, it does not work.

 

I hope for a Unity official answer too. About OneSignal, perhaps it's crashing because of something else, sometimes it can be caused by Minify (if it's checked, perhaps try to unchecked it).

 

I have tried deleting

org.jetbrains.kotlinx.kotlinx-coroutines-core-1.7.1.jar

and keep the -jvm one (so the other one compared to your solution).
Doing that the build is starting correctly.

But I am not really confident with this approach. I hope someone from Unity will answer here.

 

I fixed it by adding following code in custom launcher gradle template. I am not sure if this is the right way to do it, but it works.

Code (CSharp):

1. packagingOptions {
2.  
3.            exclude('META-INF/kotlinx_coroutines_core.version')
4.  
5.     }

 

Thank you @securegames123, it works fine when I try to build .aab.
Do you know also how can we get it working for .apk builds?

 

Thank you @securegames123, can you share your complete custom launcher gradle template file here

 

I was able to build the .aab file with this launcherTemplate.gradle

Code (Boo):

But this does not work for .apk build. I'm still looking for a solution for apk files.

 

Here is the code, it should work for aab and apk as well

Unfortunately, it doesn't work for apk build

 

I solved it by reverting back to an old MAX and old GA version. Both latest versions of their respective plugin triggered that error for me. Maybe that helps someone.

 

Can you clarify what MAX and GA are?

Same for me. The only way I found to build an apk is to delete one of the 2 .jar that are triggering the error. But this is not actually a fix.
I'm still waiting for an official answer from Unity on how to handle this.
@yunanhou, do you have some news about this topic?

 

@el_Guero I have similar problem about org.jetbrains.kotlin:kotlin-bom:1.8.10 too. And according to my research, this could be related to the internet? Like if the dependencies are downloading from the internet, and they moved their website or something. We have to manually download it. I just don't know how to set up the kotlin file (in our gradle? or environment path?), since I am new to mobile environment in unity2D. (just my personal idea and I still haven't solved it yet)

Edit: and what project template did you use? 2D or 2D Mobile?
Edit2: I changed to 2D template and imported my 2D mobile project into it, then swapped to android. Then adjust some player settings. And resolution succeeds. (I am using LevelPlay and skip any unity ads package installation pop-up)

 

Hi, I'm experiencing the same problem. I'm using Applovin MAX, Unity version 2022.3.10f1. The errors started happening after I updated all the network sdk versions. Currently enabling Custom Gradle Settings Template, Custom Gradle Properties Template and Custom Main Gradle Template without changing anything seems to resolve the issue. Excluding 'META-INF/kotlinx_coroutines_core.version' also helps.

 

This is a OneSignal 5x issue. Deleting the coroutines libs allows me to build, but then the application crashes when calling OneSignal.Initialize();

 

As I wrote above, the issue is not strictly related to OneSignal. Furthermore it could happen even using OneSignal 3.X.
I guess the problem is still hidden and unresolved.
The worst part is that Unity is completly disappeared from the discussion.

 

This code doesn't work for me

Code (CSharp):

1.     packagingOptions {
2.  
3.                exclude('META-INF/kotlinx_coroutines_core.version')
4.  
5.         }
6.  

These lines work for me in Unity 2022.3.10f1

Code (CSharp):

1. packaging {
2.         resources {
3.             pickFirst += "META-INF/kotlinx_coroutines_core.version"
4.         }
5.     }

But I get another error now

Code (CSharp):

1. [SafeDK-ERROR] Android variants not detected.
2. Please make sure you place the directive:
3. apply plugin: 'applovin'
4. after you apply the Android plugin in your build.gradle file

 

We are having the issue after installing the latest AdMob SDK in the AppLovin MAX integration manager.

 

There's great solution:
1. Go to MaxSdk/Mediation/Google/Editor/Dependencies.xml
2. Change com.applovin.mediation:google-adapter: version from 22.4.0.0 to 22.3.0.0
3. Resolve dependencies in jar resolver
4. Done

Thanks to this thread
https://github.com/AppLovin/AppLovin-MAX-Unity-Plugin/issues/289

 

The issue regarding packaging option is going worst and worst the more you update ads packages into the project.

Now I have a collision with

org.jetbrains.kotlinx.kotlinx-coroutines-core-1.7.1
org.jetbrains.kotlinx.kotlinx-coroutines-core-jvm-1.7.1

org.jetbrains.kotlinx.kotlinx-serialization-json-1.4.1
org.jetbrains.kotlinx.kotlinx-serialization-json-jvm-1.4.1

com.squareup.okio.okio-3.0.0
com.squareup.okio.okio-jvm-3.0.0

Building .aab seems to work fine.
Building .apk is always failing, no matter which packaging option we add/remove.

Do you know if launcherTemplate.gradle file is actually used when building an apk?
It seems to me that there is no way to specify packaging option for apk builds.

 

Solution that works for me:
Add this to both

launcherTemplate.gradle

and

mainTemplate.gradle

Code (CSharp):

1. packagingOptions {
2.            exclude('META-INF/kotlinx_coroutines_core.version')
3.     }

EDIT: It's better to use pickFirst('META-INF/kotlinx_coroutines_core.version') to keep your apk/aab consistent.

There is a topic, where this problem is described in details: https://stackoverflow.com/questions...jvm-vs-kotlinx-coroutines-c/77264967#77264967

 

I had this bug with Unity 2022.3.11f1 and LevelPlay 7.5.1! I have fixed it by simply removing Vungle!

 

Hi! I'm having the same issue where if I add anything more than unityads+chartboost in the Ironsource Integration manager, I get kotlinx related errors during build.

- where are the

launcherTemplate.gradle

and

mainTemplate.gradle

located in the unity project? Does this mean for each project I now need to build it as gradle first, edit, and continue the build? isn't there a better/easier way since this is unity's "official" ad solution?

 

In general, every your Android project is built with gradle. You have no option to not use the gradle. The option you have is to manually edit gradle scripts or not. To manually edit gradle files you have to go to

Edit > ProjectSettings > Player > Android > PublishingSettings

and mark files you want to edit. There are

"Custom Launcher Gradle Template"

and

"Custom Main Gradle Template"

there. When you enable these points, corresponding files will be added to your

Assets/Plugins/Android

folder

 

thanks Kek_Chpeck! I did the steps and now it builds!



However, when launching the APK I again get NoClassDefFoundError errors

EDIT: ALso, now when I try to resolve /force resolve mobile dependencies, it says "resolution succeeded" but there is nothing added? is this on purpose?

 

I'm afraid this is not the theme of this topic. But anyway check External Dependency Resolver warnings. It could ask enable some other gradle templates, when you enable main or launcer templates. I do not clearly remember, and can't check right now, but it, porbably, want you to enable Custom Gradle Properties Template. After you do, It will add your dependencies as build-time dependencies to gradle files instead of downloading them and put to Android/Plugin.
