Automatically generate archetype-catalog.xml in Archiva repository

Hi you guys

I'm facing a problem to make an archetype catalog avaible in a server.

What i really want is to run something like(or anything else that can do the
same) the maven command "mvn archetype:crawl" in the server, so the catalog
is automatically created and I could get the link of this catalog and use it
to create projects from Eclipse e.g


Is there a way to do it? Please let me know if does.
