Maven 2 error

[Simon Matic Langford <si...@pcmsgroup.com>]

Hi,

I downloaded maven2 and tried to follow the getting started
instructions, so I ran:

m2 archetype:create -DgroupId=com.pcmsgroup.v21.common.logging
-DartifactId=v21-common-logging

as detailed, and once I'd sorted my proxy settings, all looked well,
until I got the little stack trace at the end. From what I could
find on mailing lists it seems to be an invalid or missing dependency,
how can I fix it? Also where'd the wiki go? FAQ's for M2
would be quite handy.

Thanks

Simon
