The most likely cause is probably that your networks proxy hasn't been configured properly in your maven settings.xml file, alternatively your proxy may be blocking the downloads or you were just unlucky and the site was down!

XML support is something I've been pondering over as to how easy it would be to do. If I get some free time I might put together a prototype to see how well it would work as currently the application I'm working on does the JAXB route and it isn't great, particular with respects to updating different fields and re-execution of rules.
