Trying to deploy on a remote JBoss AS 6.0.0.Final. Looks like the Cargo pom is using a repository which has recently been deprecated. See JBoss discussion after the stacktrace.
"Just to provide an update, there is currently no plan to re-enable this repository URL. If you find that projects/archetypes have a dependency on this repository URL, please file a jira with that project to fix their poms to point to the new repository URLs described in the wiki."
