Thanks Dennis
1. Internet connection is good.
2. I destroyed the entire .m2 directory two hours ago and restarted with a
fresh download of Maven.
3. I am working from home. There is no proxy that I know of and only a
simple domestic firewall.

Subject: Re: Beginning Maven
The problem is that Maven is unable to download the artifact-plugin for you.
[INFO] The plugin 'org.apache.maven.plugins:maven-archetype-plugin' does
not exist or no valid version could be found
The most common reasons for this message are (in no particular order):
- You don't have a connection to the internet
+ Solution: connect to the internet
- The meta-data for the plugin in question has been corrupted in your
local repository
+ Solution: Remove the entire directory for that plugin in your local
repository
- You are behind a proxy or firewall that prevents Maven from accessing
the central repository
+ Solution: configure Maven to handle this, see
http://maven.apache.org/guides/mini/guide-proxies.html
If none of the about helps you, please run Maven like this to give us
more to go on. It will enable debug mode. Please post the results here.
