Bug 2023.1.0a20 Gradle Fail (Android/IL2CCP)

I am unable to compile builds for android in Unity 2023.1.0a20. The build fails during compilation and gives me the following errors.

Code (CSharp):

1. 2023\Library\Bee\Android\Prj\IL2CPP\Gradle\unityLibrary\src\main\java\com\unity\oculus\OculusUnity.java:32: error: incompatible types: View cannot be converted to UnityPlayer
2.                     player = (UnityPlayer) vg.getChildAt(i);

Looks like updating my Oculus package managed to fix the issue. It's also possible that renaming a specific file helped, just in case anyone encounters the same issue:

C:\Unity Editors\2023.1.0a20\Editor\Data\PlaybackEngines\AndroidPlayer\SDK\build-tools\32.0.0\lib\d8.jar renamed to "dx.jar"...

 

Hi @flimflamm,
how did you managed to get it work.
I have the same issue in 2023.1.0b1. Did you have done anything else?
I freshly installed the Oculus Package and also renamed the file.

 

This Unity Gradle issues go back 6 years, so how long before Unity fixes it or at least provides an answer that actually works? Unreal and other Game Design Platforms are raking in new customers because of this.

 

Unity's Gradle issue is 6 years old now. This shouldn't even be an issue if Unity would actually do something to fix this after this time.
Just giving business to Unreal, Godot, etc.
