Bug Constant version-nonspecific Android Gradle build error

Myself & my co-developer have been experiencing a non-stop error when trying to build for Android with our project, for the past month and a half. It has persisted across a Unity update, a Unity downgrade (which we reverted after it did not fix the error) and a multitude of tests, up to and including exporting the project and trying to build it with Android Studio. We're looking for a solution, our only possible alternative at this point is to try and migrate to a new unity project.

It appears that the issue is something along the lines of

Gradle Build Error



Failed to execute :mergeNativeLibs

OR

Gradle Build Error



Failed to execute :releaseNativeLibs

This is not an exact copy, as building takes a long time due to this being an XR project. However, I can build and have an actual copy of the error if requested.
Does anyone have a similar issue, and if so, do you know a concrete fix?

This is also an extremely urgent issue for me, as we have a major release coming up shortly and while I can release without an android build I would strongly like to avoid it, same with migrating the project.

Project information:
Unity 2021.3.2f1
Universal Render Pipeline

My sincere apologies if this is the wrong place for this thread, but I'm running out of options.

 

Update - here is a full copy of the Gradle error. I am unsure as to how to continue.
Sorry to dump an entire stack trace, but I don't know how else to convey the issue.

CommandInvokationFailure: Gradle build failed.

Update: It is an issue with IL2CPP somewhere, I attempted a build with Mono and it built successfully. However, due to platform restrictions, I am forced to use IL2CPP. I am looking into what causes this issue, still.

 

Android build not building:

First, make a blank project with a single blank scene and prove that it builds successfully.

If it does NOT build, then go fix your Unity installation, or your other tools, such as Android SDK, NDK, JDK, etc.

Until you can build a blank project to the target platform, don't fiddle with anything else.

Once you can build a blank project, now bisect the problem by bringing over parts of your current project and building it one subsystem at a time, perhaps stubbing things out that might trigger compiler errors.

Most often things that prevent building are third-party libraries such as Firebase.

Once you identify the subsystem, go to the documentation for it and make sure you are doing it correctly.

It may also be helpful to work through a tutorial or two for that subsystem.

 

Hello, sorry for the late update, in my case it was that both the Open XR Oculus Quest Support and the Oculus Integration Package were both active at the same time, causing a library duplication. Thank you for your time.
