Note that I get the same error no matter what plugin I try to install.
I can however install the same plugin via eclipse indigo with no errors. However, even after I install it I am not able to successfully run setup on configure the plugin in eclipse. I followed the steps I could find online about settings up the plugin after it is installed but I always get the following error in eclipse

**ERROR** [arquillian] Plugin is not usable in current scope or project.

and the more detailed version when I run the same command from a CLI

**ERROR** [arquillian] Plugin is not usable in current scope or project.
org.jboss.forge.shell.exceptions.PluginExecutionException: Plugin is not usable in current scope or project.

Note that I have my forge exploded under a mounted drive (under /media/...) not under my user home directory. I am throwing that here in case there are some permission issues.
Thanks,
