How to set up a multi-module project with equal hierarchy modules in IntelliJ?

I am wondering how to configure the following project layout in IntelliJ:

  1. An Android application
  2. A server back end feeding data to this application
  3. Bean classes that are shared between back end and Android application

Initially, I wanted to create three modules on an equal hierarchy level. However, this does not seem to be possible with IntelliJ. I can only add new modules inside of the first module. I wonder if this is the way I am supposed to do it? Or is there a better way to do configure this project layout with IntelliJ? Do these hierarchies only represent folders?

I feel like I should make (3) a library module and add dependencies to (1) and (2). Since a module is defined as a discrete unit of functionality which you can compile, run, test and debug independently I feel like this is the right approach.

This is my first multi-module project in IntelliJ. Any explanation is appreciated!

If you want to add them on a already initialized project, the trick from @CrazyCoder works, but you must not choose Empty Project, but instead Empty Module (in the Project Structure -> Modules dialog).

Then, choose the existing project.

Lastly, on the right side, the content root might be wrong. Set it to the root of your module.

Make sure the submodules are not on root level on the Project Structure -> Modules page. If they are, remove all expect the root module, delete the content root on the right, and add it again.

When creating a new project you can use the Empty Project option on the first wizard step. When the project is created, add 3 modules in different folders under the Project Structure settings.
