DESCRIBE THE ISSUE IN DETAIL:

I maintain a Gradle plugin that, among other things, depends on:

• com.android.tools.build:android-gradle-plugin
• com.android.tools:r8
• com.android.tools:repository

On AGP 7.4.0-alpha08, my project builds without warnings or errors. When I update it to alpha09, I see the following build failure (due to enabling warnings-as-errors):

> Task :compileJava FAILED
warning: unknown enum constant TaskCategoryLabel.AAR_PACKAGING
  reason: class file for com.android.ide.common.attribution.TaskCategoryLabel not found
error: warnings found and -Werror specified
1 error
1 warning

This enum comes from sdk-commons. I don't explicitly depend on this, and interestingly, none of my code seems to reference it, either. Adding a compileOnly dependency on sdk-commons resolves the error; it appears to me as if AGP transitively depends on sdk-commons, and between alpha08 and alpha09 something in that transitive chain changed from an api dependency to an implementation dependency.

STEPS TO REPRODUCE:

1. git clone https://github.com/keepsafe/dexcount-gradle-plugin
2. git checkout agp-7.4.0-alpha09
3. Comment out line 90 of build.gradle
4. ./gradlew compileJava
