I am creating a custom maven archetype. I have defined the archetype.xml file under the src/main/resources/META-INF/maven. I also have included the default Java classes under the src/main/resources/archetype-resources/src/main/java. However I am not sure as to how can I parameterize the package names for the Java classes when the actual maven project gets generated. The basic [maven guide to creating archetypes](https://maven.apache.org/guides/mini/guide-creating-archetypes.html) does not seem to have details around this. Any ideas as to how this can be done ?
