This will enable you to use it as a dependency pretty much the same way and you don't have to create a custom artifact type handler.

Check your mailbox. While I can’t send around actual project related material because of NDAs and stuff, I can send you some sterilized information.

Hope the info helps.

Your questions:

My project root
|
|-EJB1 project
|-EJB2 project
|-WAR project
|-JAR project
|-EAR project
|-Project project

The project project has all other projects as modules (by using relative paths). The EAR project has the various required EJBs, WARs and JARs as dependencies. Also the project project is declared as parent by all other projects.

Also note the documention on the EAR, EJB and WAR plugin pages.
http://maven.apache.org/plugins/maven-ear-plugin/
http://maven.apache.org/plugins/maven-ejb-plugin/
http://maven.apache.org/plugins/maven-war-plugin/

Don’t forget the examples. Also a good reference is Beter Builds with Maven. It’s a free download only a registration is required. It actually is a must read: http://www.mergere.com/m2book_download.jsp

Does the EAR plugin expect a certain project directory structure? If so, is it documented somewhere? 2. The "archetype" plugin can generate the structure for a "simple" J2EE project. Did you use that to create your project's structure, or did you create yours manually? 3. Could you please post your project's structure and your POM?
