Eclipse & Maven project directory structure dilemma

[Kumar, Vaidhyanatha K.]

The existing project looks like this
ProjectA  -- project_a.war
    mod1 --mod1.jar
        src/java
        web
    mod2 -- mod2.jar
        src/java
        web
    mod3
    .......
..........
 
 
To use maven & eclipse,
    Should be creating project & subprojects and convert them to eclipse project ??  
Since mod1, mod2 etc are identical in the directory structure , I think it is a 
overkill to create various subprojects. The source code mod1, mod2 etc are in 
Clearcase.
How do I move forward?
Thanks for your help.
