Solved Problem With Deploying my plugin.

So i wanted to test my first plugin that i made but the problem is that it wont open in the server.
If i type /plugins it says that there are no plugins, I dont know if you guys need the source but i can add if it's needed.

 

Did you add it to your folder?

If you monitor your console does it say it is enabled?

 

22:32:18 [SEVERE] Could not load 'plugins/joinmessage.jar' in folder 'plugins'
org.bukkit.plugin.InvalidDescriptionException: Invalid plugin.yml
at org.bukkit.plugin.java.JavaPluginLoader.getPluginDescription(JavaPluginLoader.java:257)
It say's it's my plugin.yml

My plugin.yml :
name: Jesper
version: 1.0.0
description: This plugins give's you new join and
leave messages
author: jiesper2000

main: me.jesper.join.JoinMessagePlus

 

jiesper You have a line break between
"description: This plugins give's you new join and " and
"leave messages". Remove it and you should be fine.
