build.gradle file missing namespace

[sjohnson12886]

For projects using AGP > 8.2, all build.gradle files(including ones in plugins) are required to have a namespace. If a namespace is missing in any plugin, the following error is seen

Namespace not specified. Specify a namespace in the module's build file. See https://d.android.com/r/tools/upgrade-assistant/set-namespace for information about setting the namespace.

If you've specified the package attribute in the source AndroidManifest.xml, you can use the AGP Upgrade Assistant to migrate to the namespace value in the build file. Refer to https://d.android.com/r/tools/upgrade-assistant/agp-upgrade-assistant for general information about using the AGP Upgrade Assistant.
