Velocity verbosity errors

This bug is about the importance of Maven's first impression. I'm a new user trying to follow the procedure in the book (better builds with maven) . I had two issues that made me wonder about the stability of the product. I love the ideas behind maven and I would hate to see the progress of the product slowed due to a bad first impression.

#1) When issuing the archetype command it stopped in the middle of the procedure without an error message. I re-issued the command and it worked the second time around.

$ mvn archetype:create -DgroupId=com.mycompany.app -DartifactId=my-app

#2) When issuing the command "mvn site" there are ERROR messages that appear on the screen, again making me wonder about the stability of the product. See section of output below:
