Help with Making Commands

Recently I started making a plugin, and i have tried to make a command /pn info that displays information about the plugin. When i go ingame and type /pn info it says unknown command, but /help pn brings up the command. Here is my code

Main Class

Code:java

package me.alcodes.pn;
import org.bukkit.plugin.java.JavaPlugin;
public class Main extends JavaPlugin {
    public static void main(String[] args){
            }
            public void onEnable() {
                    String author = "BigAl512";
                    String version = "1.0 Beta";
                    getLogger().info("Player Join has been Enabled!");
                    getLogger().info("Player joins is currently developed by " + author + "And is running version " + version);
            getServer().getPluginManager().registerEvents(new JoinEvents(), this);
            getCommand("pn info").setExecutor(new Commands());
            }
    }
Command Class
 

Code:java

package me.alcodes.pn;
import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
public class Commands implements CommandExecutor {
    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args){
        if (cmd.getName().equalsIgnoreCase("pn info")){
            Player player = (Player) sender;
            player.sendMessage(ChatColor.BLUE + "[" + ChatColor.GRAY + "Player Notifications" + ChatColor.BLUE + "]" );
        }
        return false;
    }
}
 

Plugin.yml

Code:

 name: Player Notifications
version: 1.1.0
description: This plugin is so awesome!
# We could place every author in the authors list, but chose not to for illustrative purposes
# Also, having an author distinguishes that person as the project lead, and ensures their
# name is displayed first
author: BigAl512
main: me.alcodes.pn.Main
database: false
commands:
  pn info:
    description: Information about Player Notifications
    aliases: [pn about]

You don't need public static void main(String[] args) as it is a Bukkit plugin...

 

I hate to be "That guy" but what the hell are you doing?

I highly recommend you take a look at this document.

http://wiki.bukkit.org/Plugin_Tutorial

 

I could point out so many errors but it would take a while.

Would be nice if you learned a little bit of Java and some Bukkit API and then come ask for help if still needed.

 

Whoops. I realised that i needed to make a sub command, as spaces dont work
Thanks for your help and comments
