NullPointerException generating archetype when mirrors are in settings.xml
--------------------------------------------------------------------------
Key: ARCHETYPE-177
URL: http://jira.codehaus.org/browse/ARCHETYPE-177
Project: Maven Archetype
Issue Type: Bug
Components: Archetypes, Generator
Environment: Windows XP Pro
Reporter: Frank Adcock
When attempting to generate any archetype from the mvn archetype:generate
command I get a null pointer exception thrown if I have mirrors defined in my
settings.xml file. I believe there is a related issue where mvn package will
also get a null pointer exception if a repository specified in the project pom
does not have a matching mirror id in the settings.xml. However, the stack
trace for the archetype generation is:
Choose a number: (1/2/3/4/5/6/7/8/9/10/11/12/13/14/15/16/17/18/19/20/21/22/23/2

These mirrored settings work for other builds within eclipse, just not from the
archetype generation, so the proxy repo is working well, but the null pointer
exceptions make it difficult to figure out what the problem is.
