Gradle build fails only when building many assets using 'BuildPipeline.BuildPlayer'

I have a Unity project I build via the command line using 'BuildPipeline.BuildPlayer', specifically as part of my CI solution, and I have run into a frustrating error when attempting to build the Android version of my project this way.

What makes this frustrating is that when I manually build the project from within the editor, it builds just fine. This is with Unity version 2021.1.5f1.

I have attached the 3 errors that I get when attempting to build via 'BuildPipeline.BuildPlayer'.
The relevant errors as far as I can tell are as follows:

Code (shell):

1. WARNING: The option 'android.enableR8' is deprecated and should not be used anymore.
2. It will be removed in a future version of the Android Gradle plugin, and will no longer allow you to disable R8.

The project uses AddressableAssets and has many sprites. For this reason, I thought it may be this bug reported here. However, I do not see more than 680 assets in my StreamingAssets folder. Although AddressableAssets could be deleting them after it is finished. Unfortunately, the suggested workaround in the comments did not work.

I have tried building on a clean machine with a clean install and even tried moving the assets over to a new project. The code-only builds fine, but it breaks when I add all the assets. I have tried some suggested Gradle options for similar issues, but those didn't seem to have any noticeable effect.

Any advice on if this is a known Unity bug or if there's a workaround would be appreciated.

 

Has anyone experienced the same issue, or does anyone have an update on this?
It really breaks our CI pipeline.

 

Thanks for the response.
I decided to wait until 2021.1.9f1 was released, as that bug report was supposed to be fixed in that version, but I am still running into the issue.

Do you have any other tips that I could use to help debug this issue?
