I got the same error yesterday. I didn't finish to find the solution yet but I have a idea why we have this errror.

After hours of digging in the maven-archetype-plugin, I didn't notice something strange...

So i decide to run the same command again with a tcpflow running to capture the sended request. Here is the result :

192.168.000.010.59775-185.031.016.185.00080: GET /maven2/archetype-catalog.xml HTTP/1.1

So, a Guru Meditation error. I like Varnish !! After that, I notice using netcat that, if you add a User-Agent (anything) in the request, everything works fine !!

So, if you add a User-Agent in the request, everything will work. I thinks with the settings.xml but I don't know how for now.
