You have to modify the created project to adjust it to an EAR project:

• In the file « pom.xml », change the « packaging » value to « ear » (if the packaging element is missing, add a new one)
  

  <packaging>ear</packaging>

• In the file « pom.xml », add the configs of the plugin "maven-ear-plugin" (see bellow an example of the "pom.xml")
  
  
• Clear the contents of the folder « src/main/ »
  

  $ rm -rf src/main/*

• Clear the contents of the folder « src/test/ »
  

  $ rm -rf src/test/*

• In the folder « src/main/ », add a new folder « application » (the contents of this folder will be added to the "ear" file of the application)
  

  $ mkdir src/main/application

• In the folder « application », you can add the folder « META-INF ».
  
  
• In the folder « application », you can also add other configuration files specific to the application server where the EAR will be deployed.
