Please help!!

Hello all,
Iam just started learning Java bukkit and i would like to create plugins.

but when i create any plugin then i install it on my own server
Iam getting a error
I don't know what is a problem?

This is the script:

package me.test.test;

import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;

public class test {

public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args){
if(cmd.getName().equalsIgnoreCase("KillPlayer")){
Player target = sender.getServer().getPlayer(args[0]);
target.setHealth(0);
}
return false;
}


}​

And this is the error




Iam using : bukkit-1.6.2-R0.2-20130908.060124-17
I added it on External jars ..

Could someone tell me what's the problem??

thanks!

 

It seems your plugin.yml is missing/invalid. Your main class must also extend JavaPlugin.
