In module settings you can choose to export some of the module libraries/src folders/dependent projects.
According to the documentation (i will use the mod3 depends on mod2 depends on mod1 example), when you choose to export a dependent project, only the direct project is exported not its own exported items.
In the example
mod1 exports a library, lib
mod2 depends on m1, sees the exported library (lib)
mod3 depends on m2, but does not see the library exported by m1 (lib).
(What is not stated is if mod2 exports m1 or not in that example)
The documentation states that if you want to export both a dependent project AND its own exported items you should export them explicitly. How do you do that ? Is there a way to "deep export" aka export an item and all its own exported entries ?
