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 the EAR?

The manual procedure is to put WAR inside EAR and add module to application.xml. I would like to automate that.

EDIT: small clarification - the WAR project is using maven but for EAR I have only the binary file nothing more.

Answer 1

I'd create a new module that has <packaging>ear</packaging>.

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

<dependency>     <groupId>com.your.group.id</groupId>     <artifactId>your-war-artifact</artifactId>     <version>your-war-version</version>     <type>war</type> </dependency> 

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

<plugin>     <artifactId>maven-ear-plugin</artifactId>     <version>2.3.2</version>     <configuration>         <finalName>MyEarFile</finalName>         <version>5</version>         <generatedDescriptorLocation>${basedir}/src/main/application/META-INF</generatedDescriptorLocation>         <modules>             <webModule>                 <groupId>com.your.group.id</groupId>                 <artifactId>your-war-artifact</artifactId>                 <uri>YouWarFile.war</uri>                 <bundleFileName>YouWarFile.war</bundleFileName>                 <contextRoot>/appname</contextRoot>             </webModule>         </modules>     </configuration> </plugin> 

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

Now create a parent module (with <packaging>pom</packaging>) and add the war module and the ear module to it. Make sure you set the <parent> 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.
