No room to fit Maven-Ear-Plugin in one pom.xml

After I have the WAR file build completed, then I'm going to build the EAR file. Unfortunately it doesn’t work as in ANT. In Ant I can do all stuff of work in just one build.xml but not in Maven. Too bad huh?!! OK, I understand this can't be done but I still insist want to do it. Anyhow, there is still no EAR file being generate after the build. What a joke? No joking, Maven doesn't allow me to do that. Take the following code snippet as my use case:

    4.0.0
 
    org.huahsin
    MyWebService
    0.0.1-SNAPSHOT
    war
 
    MyWebService

    
        
         org.huahsin
         MyWebService
         0.0.1-SNAPSHOT
         war
        

        ...
        ...

    

    
        
            
             org.apache.maven.plugins
             maven-ear-plugin
             2.9.1
             
                 7
                 
                     
                         org.huahsin
                         MyWebService
                         MyWebService.war
                     
                 
                 MyWebService
             
            
 
            ...
            ...
 
        
    

The <packaging> will cause by the build failed. I mean it would working fine for building WAR file but not for building EAR file. Now I have knew the root cause, changing to ear in <packaging> line but I'm still not satisfied with the final output. Because I have a special requirement to this EAR file not to contain all other libraries except the custom build library. Now the EAR file has mess up all others libraries in it, this could a disaster when I deploy to WebSphere Application Server.

To make it clean, I create another pom.xml that only perform one task, which is EAR packaging. And this pom.xml contain only one dependency which is my newly created WAR. To make the picture clear, the WAR file should contain all only the libraries, whereas EAR file should contain only the WAR file. This is the primary objective of having a separate pom.xml, following code snippet worth thousand of these nonsense.

    4.0.0

    org.huahsin
    MyWebServiceEar
    0.0.1-SNAPSHOT
    ear

    MyWebServiceEar

    
        
         org.huahsin
         MyWebService
         0.0.1-SNAPSHOT
         war
        
    

    
        
            
            org.apache.maven.plugins
            maven-ear-plugin
            2.9.1
            
                7
                
                    
                        org.huahsin
                        MyWebService
                        MyWebService.war
                    
                
                MyWebService
            
            
        
    

Now I have another question, how could I fit 2 pom.xml in one project? I don't know??? I just put them somewhere as long as there wouldn't crash each other in the project. Am I doing this in the right approach?
