Installer jar is not getting executed using the following pom with izpack - maven

Question

I tried making an izpack installer using maven. The problem that I'm facing is that in the build the 'install.xml' and the other resources are just being copied to the install.jar. The XML file is not parsed and hence the install.jar is not getting executed.
Please help in rectifying the issue.
