maven-ear-plugin - How to manipulate Manifest.MF of webModule and ejbModule?

Tue, 10 Jul 2012 04:51:15 -0700 

Hello,

I have a multimodule maven project with the following structure:

|     app (parent)
    -- pom.xml
    -- app-ear
       -- pom.xml
    -- app-ejb
       -- src
       -- pom.xml
    -- app-web
       -- src
       -- pom.xml
|
This is my *app/pom.xml* (parent project) where I put all my application dependencies:

My problem is that /app.ear/app-web.war!META-INF/MANIFEST.MF/ and /app.ear/app-ejb.jar!META-INF/MANIFEST.MF/ looks like this: 

|     Manifest-Version: 1.0
    Build-Jdk: 1.6.0_24
    Class-Path: lib/javax.faces-2.0.9.jar lib/richfaces-core-api-4.2.0.Fin
     al.jar lib/richfaces-core-impl-4.2.0.Final.jar lib/richfaces-componen
     ts-api-4.2.0.Final.jar lib/richfaces-components-ui-4.2.0.Final.jar li
     b/cssparser-0.9.5.jar lib/sac-1.3.jar lib/guava-10.0.1.jar lib/jsr305
     -1.3.9.jar
    Created-By: Apache Maven
    Archiver-Version: Plexus Archiver
|

And I really have to remove the Class-Path entry from these MANIFEST.
Why? Because it seems that RichFaces is being loaded two times in classpath of my application. (One from app.ear/lib folder and another from app.ear/app-web.war!META-INF/MANIFEST.MF Class-Path entry). And when I try to deploy app.ear in my Application Server (Oracle Weblogic 10.3.5) I get some errors like that: 

|     INFO: Unsanitized stacktrace from failed start...
    java.lang.IllegalArgumentException: duplicate key: class

It's weird that if I run |mvn package| in my *app-web* project, the Class-path entry does not go to app-web.war/META-INF/MANIFEST.MF. It only occurs when I run |mvn package| in my *app* parent project.
So, how could I remove the Class-path entry of webModule and ejbModule MANIFEST file?
I found a similar problem in this thread <http://stackoverflow.com/questions/9237485/how-to-set-up-manifest-class-path-properly-in-maven-war-plugin> but without a solution. 

I appreciate any help.

Thanks,
Mauricio
