Game Play Services - Resolver bug still in Unity 6 - SDK 34/35 [FOUND WORKAROUND TEMP SOLUTION]

Unity Engine
, ,
1

Hey all,

For the life of me, I cannot figure out which game play service plugin will work with unity 6. It constantly throws Gradle error and cannot force resolve. Specific error: "What went wrong:

Could not create an instance of type org.gradle.initialization.DefaultSettings_Decorated.

Could not initialize class org.codehaus.groovy.reflection.ReflectionCache"

I have tried almost every version plug in from the latest 11.01, to 10.14, 10.12, you name it. I don’t have any issues building out my build for android using 10.14, in unity 2023, 2022, or 2021. I obviously don’t want the unity splash screen, so for now, 6 is my only option.

Unity, what’s going on, I thought version 6 was supposed to be the best and most reliable unity ever and yet, this issue still consists?

Reproduce it:

new project
download any version of game play plugin from git (preferably 10.14)
after install, force resolve it and you’ll get the same Gradle error over and over regardless of trying to manually change Gradle version in wrapper properties, etc.

Here is the entire error in case anyone at unity has a solution:

Gradle failed to fetch dependencies.

@jamess_unity - I saw you posted about Unity 6. Any thoughts on this?

Ok found a workaround temp fix. @unity needs to resolve this matter but here is the workaround that just worked for me. I have two projects of my game, one in unity 6 and one In unity 2023. Install the same plugin in both, so for me that was 10.14. Go to the 2023 (or older) stable version where force resolver works no problem. So what you do is after force resolve, look in Assets\Plugins\Android. You’ll see dozens of plug-ins. Reveal that plugin folder in finder. Now go back to Unity 6. Make sure your android setup (window> google play games) is done, then go to external dependency and do a regular resolve, not a force. Because of the bug, there should be no plug-ins in there, and if there is, delete whatever is in there except GooglePlayGamesManifest. Reveal that folder in finder. Now copy everything in the 2023 plug in folder and paste it into the unity 6 plug in folder. If it asks to replace certain files, click replace. Come back to unity 6, all the plug ins should now be in there.

DO NOT FORCE RESOLVE - DO NOT REGULAR RESOLVE - DO NOT DO THE GOOGLE PLAY GAMES ANDROID SET UP - DO NOT BUILD AND RUN - DO NOT DO ANYTHING NOW EXCEPT THIS

  1. Make sure your publisher settings and player settings, etc are how you want it to be for the build. SDK MINIMUM SHOULD BE API 26 and set target to 35. You must set min to 26 or it will crash.
  2. DO NOT BUILD & RUN - if you do, it will remove the plug ins and you’ll have to copy and paste again and it will throw the Gradle error
  3. INSTEAD do build profiles and just make a regular build FIRST
  4. It should now successfully build it out without the Gradle issue (no clue why)
  5. NOW, after it successfully built it, press build and run and it’ll successfully install the apk onto your device. Again, if you do build and run first, it won’t do a successful build.

ALSO - ANOTHER SUGGESTION
For the time being I would uncheck “enable auto-resolution” and “enable resolution on build” in the external dependency android resolver settings. If you don’t disable these two, every time you close and open your project, you’ll have to copy and paste the plug ins again. You also don’t need to do the android setup anymore either, it’s already set and if you do that, you’ll have to once again copy and paste the plug-ins.

This is my temporary fix for now. Unity, please figure out what’s going on. Hope this helps someone else

@Ohyouknow I will forward this onto the mobile team, thanks for raising the issue

Hi @Ohyouknow , glad to hear your temporary fix has worked.
This sounds like a third party (Google) issue. Please report it to Google external dependency manager or the Google games plugin . This issue looks relevant
Could not initialize class org.codehaus.groovy.vmplugin.v7.Java7 · Issue #384 · googlesamples/unity-jar-resolver · GitHub so you may want to try some of the steps there too.

thank you, I appreciate it!

I tried all the suggestions there and none of them worked for me sadly. Still using the current workaround.

hi @jamess_unity and @pixelsprite_unity

After further testing I noticed a strange Gradle error that I wanted to send your way to check out

Using the latest Unity 6 release, with googleplaygames plugin 10.14 and externaldependencymanager 1.2.183, my workaround was working fine and then when I went to make my final build for release with SDK 35, it started crashing giving me duplicate library errors, Gradle errors, amongst other things like saying the SDK wasn’t meant for 35, but its meant for 34 (clearly not correct), etc.

The weird thing was the only change I made was I added ASTC in my texture compression formats in player settings. I have ETC2 and ASTC, in that order. When I pressed build, it crashed. I then removed ASTC, and the build went through without any issues.

I’m not sure how they correlate, but wanted to pass that along to you team.

EDIT: After further testing, the issue is not just ASTC, it is having more than more compression format. I removed ETC2 and left ASTC, and the build worked fine. I wonder if there is a bug that correlates having more than one compression format with the Gradle or buildout process for the SDK?

Does anyone have a solution for this problem? I have been struggling and frustrated for 2 days and all kinds of errors are now errors in unity 6 version

For me its other problem. I have my game already published, using Unity 6. I wanna add Google Play Games Service for Login and Achievements. I added unitypackage GPGS 2.0.0 (newest from github) and cant build app anymore. Getting error:
Unity 6000.0.36f1.
Tried everything (while there is not much info about 2.0.0 at all) and can’t build my .apk at all. Apparently fails try to look for maven at:

I check these urls from fail console message and they are empty…
