In Maven2, what's the simplest way to build a WAR and the EAR to contain that WAR in a single POM?

Question

Situation is pretty straightforward. I have a Java webapp that I\'m converting to be built with Maven. At present, the app is built with Ant into a single WAR file, which is the

Answer 1

In Maven every single project produce an aritifact. In your situation I suggest create two project one for war and one for ear. If you need mutltiple versions of your projects you can achive that using classifiers and profiles.

This is excerpt of richfaces examples pom.

    
        maven-war-plugin
        
          
            jee5
            package
            
              war
            
            
              ${project.build.directory}/${project.build.finalName}-jee5
              jee5
              WEB-INF/lib/jsf-api*,WEB-INF/lib/jsf-impl*,WEB-INF/lib/el-*
              WEB-INF/lib/jsf-api*,WEB-INF/lib/jsf-impl*,WEB-INF/lib/el-*
            
          
          
            tomcat6
            package
            
              war
            
            
              ${project.build.directory}/${project.build.finalName}-tomcat6
              tomcat6
              WEB-INF/lib/el-*
              WEB-INF/lib/el-*
            
          
        
        
          
            
              ${basedir}/src/main/java
              /WEB-INF/src
            
          
        
      

In your ear pom use profiles to import required dependency with appropriate classifier.
