[jboss-user] add Maven repositories to JBoss standalone

Hi. I'm working with JBoss AS 7.1.1.Final and I want to add Maven repositories to an standalone instance. I'm adding capabilities to standalone.xml file by hand, in an OSGi subsystem to fulfil my project dependencies. Some of these capabilities are not in JBoss Maven repositories. How can I add more repositories to resolve my project dependencies? It is a little bit tedious adding the dependencies by hand, one by one, in the standalone.xml file. Is there a better way to achieve a dependency tree in a more automatic way? Thank you!
