Multi Project Play Application Dependency

Is it possible to create a game project based on another game project that has code stored in different locations? (Not under the same root).

I want to split my application into something like a regular application and a business application, where a specific business application depends on a regular application.

Using the Java Playback Platform.

Saw some examples (scala) but they have all the code together in different folders but under the same root.

Or do I need to store the generic code somewhere as a maven project and add it as a dependency in the business-play-app? What are the best practices?

Thank.
