Have you used the Forge installer?

Ok, so I managed to fix the issue it was the Scala package downloaded by the server was corrupt god knows how that happened as it was a fresh install of forge, either way I managed to fix it by downloading scala-library-2.10.2.jar from the web.

I've also tried it without mcpc+ and I still get the same error,

With my modpack on the server it gives me an error I am using the OS Linux Ubuntu Here is the error log ---- Minecraft Crash Report ---- // Everything's going to plan. No, really, that was supposed to happen.
