Source control structure for Maven projects

[EJ Ciramella]

Hello list!  Is there any best practices docs I could be pointed to for
this?  We'd like to do something like:
 
//depot/srvcs/project/project-1/module-1/pom.xml
//depot/srvcs/project/project-1/module-2/pom.xml
//depot/srvcs/project/project-1/module-3/pom.xml
//depot/srvcs/project/project-1/pom.xml
 
What is everyone else doing?
