Eric Pabst commented on MDEP-410:
---------------------------------

In working on a build system, I needed to know what the dependencies are before 
running mvn clean install.  I would use that information to update some version 
properties and then perform the mvn clean install.  With this PR, I can have 
the build system run mvn dependency:collect to get the information I need.  It 
doesn't try to download any jar files so it doesn't care if the project (with 
intra-dependencies) has been built yet.

> dependency:resolve fails for a multi-module project where one module depends 
> on another and "mvn install" not run yet
