How to add WAR inside EAR with Maven

Question

I have EAR with an application and I need to extend this app with my own code that is packaged as a WAR. Is there a maven plugin that can help me with putting the WAR inside

Answer 1

I'd create a new module that has ear.

In the dependencies for this ear module, include your war module:

    com.your.group.id
    your-war-artifact
    your-war-version
    war

Now in the build plugins for this ear module, include the maven-ear-plugin like, e.g.:

    maven-ear-plugin
    2.3.2
    
        MyEarFile
        5
        ${basedir}/src/main/application/META-INF
        
            
                com.your.group.id
                your-war-artifact
                YouWarFile.war
                YouWarFile.war
                /appname
            
        
    

You can change the specific configuration values for the webModule as required.

Now create a parent module (with pom) and add the war module and the ear module to it. Make sure you set the of the war and ear modules corrently.

When you run mvn package for this new parent, a war file will be built by the war module and an ear file (containing the war) will be built by the ear module.
