Arranging Modules on the File System

[Eric Kolotyluk <er...@gmail.com>]

I apologize if this is a newbie question, but I'm looking for a quick 
answer...

I'm using Sonatype Maven plug-in for Eclipse and I have set up a project 
with several modules. The way the plug-in arranged them on the file 
system is:

eclipse-workspace/parent-project/.project
eclipse-workspace/parent-project/pom.xml
eclipse-workspace/parent-project/sub-project-1/.project
eclipse-workspace/parent-project/sub-project-1/pom.xml
eclipse-workspace/parent-project/sub-project-2/.project
eclipse-workspace/parent-project/sub-project-2/pom.xml
eclipse-workspace/parent-project/sub-project-3/.project
eclipse-workspace/parent-project/sub-project-3/pom.xml

The problem is that the IBM Rational Team Concert source control I am 
using chokes when I try to share and check in the parent-project because 
of the nesting. The sub-projects are fine. Can I just rearrange the file 
system so it looks like:

eclipse-workspace/parent-project/.project
eclipse-workspace/parent-project/pom.xml
eclipse-workspace/sub-project-1/.project
eclipse-workspace/sub-project-1/pom.xml
eclipse-workspace/sub-project-2/.project
eclipse-workspace/sub-project-2/pom.xml
eclipse-workspace/sub-project-3/.project
eclipse-workspace/sub-project-3/pom.xml

It was not immediately apparent to me looking at the pom.xml or the 
Sonatype UI how to do this. The POM looks like

<modules>
<module>sub-project-1</module>
<module>sub-project-2</module>
<module>sub-project-3</module>
</modules>

Cheers, Eric

Wow, thanks for the awesome tip! That's has helped clear things up 
enourmously.

It was actually fairly simple to flatten the Maven modules the way I 
suspected. It was vastly more difficult to 'flatten' the Eclipse 
projects in the file system - well actually it was easy to flatten the 
Eclipse projects, it was really difficult to figure out how.

Also, the reference you gave me has tons more considerations on dealing 
with Maven in Jazz-land.

Cheers, Eric
