Hi, since org.jboss.modules.ModuleClassLoader is not URClassloader classpath items must be obtained using other mechanism, as it's suggested here: http://markmail.org/message/ohcanda7ait7i3gl may be we can use ClassLoader.getResources("/") to get them. I'll be making some research to fix it quickly.

I've made some research about it, but I cannot find a way to obtain URL list from a non URLClassLoader. Using getResources only returns "..../classes" folder but not jars items.

While we find out a way to get classpath items from non URLClassLoader you can use maven-dragome-plugin for offline compiling: https://github.com/dragome/dragome-sdk/tree/master/dragome-maven-plugins
