MODULES-218, included in WildFly 10/WildFly Core 2.0.10, 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"/>

module add command could have optional argument --copy-resources=(true|false) with default true, which would specify how new module will look like.

• true copy files to the created module's directory = no change from how it works now.
• false don't copy files and use absolute paths in resource-root instead.

Another option could be to add optional argument without value, which would only specify to not copy files to the created module's directory and use absolute paths in resource-root instead. Name of this argument could be something like --use-absolute-paths-for-resources.
