I've tried to install the Envime-server for vim, but it keeps not-running in the editor. I did compile the server with the scala version as stated in the docs, but there's something missing I haven't figured out. Yes, I did add the lines on plugins.sbt, but whenever I check the server log, it shows it can't find the main class. Any help?
