Android gradle modules circular dependency

Question

Connecting module application and get following error:

Circular dependency between the following tasks:
:app:processDebugResources
\--- :app:processDebugResources (*)

Module structure

/app
|--base
|--authfire

Error appears after adding to authfire gradle this line api project(path: ':app')

What I actually need is simply use MainActivity class from root app inside authfire for starting MainActivity. Woud be appreciate for any help.

:app gradle

Move the common/shared code used by the two modules to another module, say common: we have,

common module

module 1 depends on common

module 2 depends on common

and so on.. this way you won't have a circular dependency issue

App is depending on authfire

authfire is depending on App

That for sure make a loop.

it seems that in project: authfire you need to use some parameters from project: App. Solution whould be like this:

App is depending on authfire (that is ok)

App is passing parameters to Project:authfire (that would be ok) (example of passing parameters is using broadcast)
