Exploding dependant jars seems to have issues for rars. I didn't work out if this is a problem in JBoss Tools or RSE. I suspect a little of both. It seems looking at the source that only the 'Local' RSE adapter correctly explodes deployments?

1) Create a maven project, set the packaging to rar
2) Create a second maven project, set the packaging to jar
3) Include the jar as a maven compile dependency of the rar
4) Import both into eclipse
5) Deploy to a remote (JBoss AS) server via RSE SSH/dstore/FTP fails

It seems the JBoss Server Adapter (I think) creates the directory:
xxxxx-1.0.rar/xxxxx-1.0.jar/
on deployment. It then requests upload for the jar over the top of the directory which fails. With FTP this looks like:
CD xxxxx-1.0.rar/
MKD xxxxx-1.0.jar
STOR xxxxx-1.0.jar <fails because directory exists>

This is my first bug opened on JBoss/eclipse, so please point me on if you think this should be opened on RSE, but I think looking at the source it belongs here.
