How to support modularization in Android app with HILT?

This interesting article from Jeroen Mols shows a possible way to modularize an Android app. It basically divides the modules in 3 layers (App, Features and Libraries). App communicates directly with Features and Features can depend on Libraries. This means that App doesn't interact directly with Libraries.

enter image description here

Now, if I understood correctly HILT documentation, the module that contains the Application (which is the App module) and thus it has the HILT entry point (HiltAndroidApp) needs to know about all other modules that want to use dependency injection. So for example if I have a library called libraries:analytics , I would need my App module to depend on it, so I would be forced to have in my app/build.gradle:

implementation project(":libraries:analytics")

which violates the separation and abstraction the whole architecture was trying to achieve.

Is my interpretation correct? If so, what would you do for not breaking the suggested architecture?

If you are using Hilt Gradle Plugin and you have transitive dependencies of other modules you can apply below to your :app/build.gradle and remove the transitive module(s) dependencies from it.

hilt {
    enableAggregatingTask = true
}
