android - IntelliJ cannot resolve resources nor AndroidManifest.xml in SBT (multi)project -

ever since i've migrated android project gradle sbt become unable work resources:

• each symbol within xml resources (e.g. @string/app_name) highlighted red , displays error message (e.g. cannot resolve '@string/app_name' symbol),
• layouts editors fail work variables in layouts unresolved, cannot edit them,

what more ide reports androidmanifest.xml missing , unable run app within ide, because unable configure run configuration. automatic refactoring of manifest , resources e.g. activity class name changed fails.

however, resources , manifest in place. facets set correctly can seen in picture:

what tried , haven't worked:

• editing facets - of them set correctly,
• invalidating cache , restarting intellij,
• removing .idea directory , reimporting project sbt plugin,
• syncing projects in gradle ones - there no such option sbt, best was refresh build.

normally suspect build reason not working, but:

• sbt clean app/android:run correctly builds application scratch , load emulated device, works expected,
• facets within ide set correctly, dependencies correctly recognized, projects correctly set up.

what can try diagnose/resolve issue?

disable source generation in ide.

resources aar not resolve in local xml resources, limitation of idea sbt project import support
