I am experimentally migrating my project to prefab. It has a prefab AAR library module and sample app modules in the project. The samples reference the library as dependencies { implementation project(':...') }.

I expected that prefab contents are resolved for project(...) too, but current AGP fails to handle it, and thus cmake build fails like this:

> Task :aapbarebonepluginsample:generateJsonModelDebug FAILED
prefabUsage: prefab [OPTIONS] [PACKAGE_PATH]...
prefabError: Invalid value for "PACKAGE_PATH": Directory "/media/atsushi/extssd0/sources/android-audio-plugin-framework/java/androidaudioplugin/build/intermediates/prefab_package/debug/prefab" is not readable.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':aapbarebonepluginsample:generateJsonModelDebug'.
> error when building with cmake using /media/atsushi/extssd0/sources/android-audio-plugin-framework/java/samples/aapbarebonepluginsample/CMakeLists.txt: Build command failed.

If I replace those dependencies with packages that were installed locally (by 'maven-publish` and mavenLocal()) then it builds. But obviously that's not how we can form the project, the dependency resolution matters.

Since the AAR cannot contain jniLibs due to https://issuetracker.google.com/issues/168777344 I am stuck with the current situation.
