Project update recommended: Android Gradle Plugin can be upgraded. Error message: Can not find AGP version in build files

Issue

After a recommendation in Android Studio to upgrade Android Gradle Plugin from 7.0.0 to 7.0.2 the Upgrade Assistant notifies that Cannot find AGP version in build files, and therefore I am not able to do the upgrade.

What shall I do?

Thanks

Solution

In my case the following steps solved this:

cd to project directory
bash ./gradlew help --scan
bash ./gradlew wrapper --gradle-version 7.0.2

See the upgrade instructions to version 7.0.2 in the gradle release notes.
