The class org.jboss.modules.MavenArtifactUtil uses a customized setup to fetch maven artifacts. It does not use maven directly.

What happens here is if the user doesn't have maven installed in the default location, or doesn't have that particular artifact installed at that time, then it will fail.

If it were to use maven directly, it would be able to fetch resources directly and could allow users to have their maven install in a non-default location.
