> h3. Assumed cause
> {{[org.apache.maven.model.Parent|http://maven.apache.org/ref/current/maven-model/apidocs/org/apache/maven/model/Parent.html]}}
> does not expose a {{getName()}}/{{setName()}} pair of property accessors.
> h3. Proposed fix
> Add {{setName()}}/{{getName()}} to the {{Parent}} API, and ensure that they
> are populated during the build/reactor lifecycle such that child poms can
> have access to them.
> Thanks.
