So i am a starter developer and i test all my plugins on a localhost server. So one day my friend gets a server and makes me his developer. I make him a test plugin with eclipse using the 1.8.3 version of spigot as my jar file and the 1.8.3 spigot API javadoc. I make the plugin and here is my pastebin of it with the plugin.yml and all that stuff and its all done correctly. Now i upload it to my localhost. It works! Then he uploads it to his server. It says nothing as if its not even in the plugins folder. Not a message in console about it not even anything in game. So then i tried fixing it but what is there to fix the plugin works just not on his server. he is running 1.8.3 spigot and has no problems with any other plugins on his server that he downloaded from other places just my plugin doesnt work. Here is my pastebin i really need help: http://pastebin.com/MBKt5dEv Heres the pastebin to my plugin.yml: http://pastebin.com/V69EgCqx Thanks and please help!
