groupId and version redundant when executing archetype with parent
------------------------------------------------------------------
Key: ARCHETYPE-64
URL: http://jira.codehaus.org/browse/ARCHETYPE-64
Project: Maven Archetype
Issue Type: Improvement
Components: Archetypes
Affects Versions: 1.0-alpha-4
Reporter: Rod Coffin
Running the archetype plugin in a parent project creates a sub-project
(module). Although the parent elements are properly set in the child pom, the
group id and version are repeated. These are not necessary since they will be
inherited from the parent. Ex:
<parent>
<artifactId>parent</artifactId>
<groupId>com.rfc.archetypes.example</groupId>
<version>1.0-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>
<groupId>com.rfc.archetypes.example</groupId>
<artifactId>example-web</artifactId>
<version>1.0-SNAPSHOT</version>
Having this information is two places is bad in principle because it violates
the DRY principle and in practice because they can get out of sync accidentally
and it could be confusing.
