MODULES-218, included in EAP 7.0.0.GA/WildFly Core 2.1.2, allows absolute paths to be used for resource-roots in module.xml. But there is no way to create module with absolute paths in resource-roots using CLI command module add.

resource-root's path previously only allowed resources within the module's directory, e.g.:
<resource-root path="wildfly-controller-2.2.0.CR2.jar"/>
With MODULES-218 it allows resources to exist anywhere on the filesystem, in the form of an absolute path, e.g.:
<resource-root path="/Users/whoever/mymodules/wildfly-controller-2.2.0.CR2.jar"/>
