It seems that you have edited the jar directly without compiling it since it seems that you have removed the ProxyServer import.
If you don't have the source of a plugin, I would recommend that you consult with the original author or else make a separate plugin

i do have the source of the plugin but what you mean by compiling? Do you mean exporting it?
