How to build maven source exports with dependencies for escrow releases
===

We need to provide releases of source code occasionally for some customers (held in escrow by a third party).

This needs to include:

 - The main maven module (or multi-module) source code
 - Source code for all dependent maven modules, where available in our source code repository
 - Binaries for all other dependent modules (e.g. third party external libraries). 
 - any other maven dependents, e.g. parent poms.

Ideally this should be an automated process. 
At the moment we don't store source jars in our maven repository and would prefer to use the scm tags in the poms and fetch the source from the svn repository. 

`mvn scm:export` works well for individual modules. If we could combine this with the maven-dependency-plugin somehow (and make sure parentpoms are included!), it would probably do most of what we need. Does anyone know of a simple way of doing this?
