Solved Unhandled exception executing command _____

Hia, I'm Pixelatorx2 an aspiring Bukkit Dev and I've recently started creating my own KitPVP plugin with listeners etc, BUT after adding some kits and stuff... It suddenly stopped working.

I'll include important details about it after

Code:

@Pixelatorx2
OnCommand is called for I think all commands, so when you try to get the player at args[0] on a command that has no arguments, it gets mad.

Stack trace line: "java.lang.ArrayIndexOutOfBoundsException: 0"
Your line: "Player target = Bukkit.getServer().getPlayer(args[0]);"

 

So I just repalce Player target = Bukkit.getServer().getPlayer(args[0]; with

Nateb1121??

EDIT: Fixed, just use Player target = Bukkit.getServer().getPlayer(commandLable);
I dont know why, but it works
