This is what I have. I tried all 4 combinations of modApi/modImplementation and with/without include, after each time running build again. build doesn't complain. However, I do not get any suggestions for Component or import dev. when I ask Idea, and searching in the external resources shows no Component interface.

What am I missing? (I'm new to gradle AND Idea, so it might be something obvious)

Okay, it seems to work when I load module by module.

No idea what you mean by "this" because that screenshot is unreadable, but guess you already fixed it
