Firebase Perf Plugin does not work with latest AGP 9 alpha

[pablobaxter]

Testing AGP 9.0.0-alpha02, I am running into the following error during the configuration phase:

* What went wrong:
An exception occurred applying plugin request [id: 'com.google.firebase.firebase-perf', version: '2.0.1']
> Failed to apply plugin 'com.google.firebase.firebase-perf'.
   > Could not create plugin of type 'FirebasePerfPlugin'.
      > Could not generate a decorated class for type FirebasePerfPlugin.
         > com/android/build/api/transform/Transform

Seems that AGP 9 will introduce some breaking change that isn't handled by the perf plugin.

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

Relevant API removal in AGP: https://developer.android.com/studio/preview/features#android-gradle-plugin-removed-apis

Hi @pablobaxter, thank you for reaching out. I was able to reproduce the issue. This might be related to the removal of the API mentioned here

Android Gradle plugin 9.0 removes: The deprecated and disabled BaseExtension.registerTransform APIs, which only remained to allow compiling against the latest AGP version while targeting running on AGP 4.2 or lower.

I'll raise this to our engineers and see what we can do here.
