Android studio 3.0, modules and IDE symbol indexing

Long in short, after upgraded to Android Studio 3.0, symbols from aar binary modules cannot be resolved in IDE, although the building/make is successful. Clean or Rebuild project is useless.   Two steps solution: Change line compile(‘the-aar-module-name’) to implementation project(‘the-aar-module-name’) Select ‘Invalidate Caches / Restart‘ from File menu.
