You can install the child project into your local repository and include it in the list of dependencies in your parent project. If you're not making changes often to the child project then I've found the install+refresh is quicker overall than having your IDE constantly scanning multiple projects to resolve dependencies.

module1 must have POM packaging

And there you have your answer. Only modules with POM packaging can contain other modules.
