Can confirm.
We use Sonar Gradle Plugin v7.2.3.7755. After updating from Android Gradle plugin 9.0.0 to 9.1.0 this error occured.
This is a major blocker, since there is no workaround I am aware of (in contrast to e.g. this AGP 9.0 issue).
This API was removed by Google (see here): srcDirs.addAll(sourceSet.getCDirectories());
Please provide a hotfix asap.
Here is the stacktrace:
