Solved Error at loading?

So I was making another plugin that bans or kicks players.
When I started the server trying to make it work this is what happend:

Code:

Here's the main class too:

Code:

public class KickBan extends JavaPlugin {
 
    public final Logger  logger = Logger.getLogger("Minecraft");
 
    @Override
    public void onEnable() {
        getLogger().info(ChatColor.BOLD.toString() + ChatColor.GREEN + "KickBan has been enabled!");
        getServer().getPluginManager();
    }
    @Override
    public void onDisable() {
     
    }

     
 
    @SuppressWarnings("deprecation")
    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args) {
        Player player = (Player) sender;
        if(cmd.getName().equalsIgnoreCase("ban")) {
            if(player.hasPermission("kickban.ban")) {
            if (args.length == 0) {
                player.sendMessage(ChatColor.BOLD + "" + ChatColor.RED + "WARNING: You must specify a player!");
            }
            if(args.length == 1) {
                if(Bukkit.getPlayer(args[0]).isOnline()) {
                    Player tpplayer = getServer().getPlayer(args[0]);
                    tpplayer.setBanned(true);
                    tpplayer.kickPlayer(ChatColor.BOLD.toString() + ChatColor.DARK_RED + "You were banned from the server by " + ChatColor.GOLD + player.getName() + "!");

                if (args.length == 0) {
                    player.sendMessage(ChatColor.BOLD + "" + ChatColor.RED + "WARNING: You must specify a player!");
                }

            } else {
                player.sendMessage(ChatColor.BOLD.toString() + ChatColor.DARK_RED + "The player " + ChatColor.GOLD + args[0] + ChatColor.DARK_RED + "is offline");
            }
        }

        }

        }
 
             
         
     

        return false;
    }
}

Plugin.yml:

Code:

name: KickBan
author: Sarcry
main: me.punisher.KickBan
version: 1.0
commands:
   ban:
      description: Punish players forever.
      usage: /<command> <player>
   kick:
      description: Kick players.
      usage: /<command> <player>

 

What timtower said ^^

But the stacktrace is throwing an error with the 'main' string in your plugin.yml. When putting the main class into the string it would be me.punisher.KickBan. It would be the main package name (me.punisher) then the main class that extends JavaPlugin (KickBan -- Hence me.punisher.KickBan).

 

Thanks for the help! I editted the plugin.yml and worked! The thing was on the me.punisher.KickBan

 

Glad I could help! Make sure you set your thread to 'Solved' so people know it's already been resolved
