Raphaël Piéroni closed ARCHETYPE-177.
-------------------------------------
Resolution: Not A Bug
Having mirrors is not mandatory, but if
one is used, then mirrorOf is a mandatory
child element of settings/mirrors/mirror.
The exception thrown (NPE) not saying
that problem is not an archetype plugin bug.
Franck, if you are still concerned with this
can you please open a new issue on the MNG's
jira project explaining the problem even linking
to this issue.
Thanks

> When attempting to generate any archetype from the mvn archetype:generate

> These mirrored settings work for other builds within eclipse, just not from
