Plugin Help /hub instead of /spawn help!!!

Hey guys, I have ran a server for a while and decided its time to take the next step and develop plugins for it.
I tried to make a plugin that does that, however when I load up the server nothing happens and it doesn't appear in plugins help!!! Here is my Code:

import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;
public class Hub extends JavaPlugin{
public void onEnable() {
getLogger().info("Plugin Enabled");
}
public void onDisable() {
getLogger().info("Plugin Disabled");
}
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
if(sender instanceof Player) {
Player player = (Player) sender;
if(cmd.getName().equalsIgnoreCase("hub")){
String hub = "spawn " + player.getName();
Bukkit.dispatchCommand(Bukkit.getConsoleSender(), hub);
player.sendMessage(ChatColor.GOLD + "Returning To Hub!");

}
}
return false;
}
}




Plugin.yml:

name: Hub
author: ironicflunky541
version: 1
description: Allows User to Teleport To Spawn via /hub
Hub: me.zack.Hub.Hub
commands:
hub:
description: Teleport To Hub!

 

What in the hell are you doing that for? Just open commands.yml in your server folder and make it look like this:

Code:

aliases:
  hub:
    spawn $$1-

 

I wanted to try and make my own plugin for once that works..... I just want to know what I'm doing wrong. I think I have the code right, however in the console it says this: Could not load 'plugins\spawnhub.jar' in folder 'plugins' org.bukkit.plugin.invalidPluginException: Cannot find main class 'me.zack.spawnhub.spawnhub. <--- that was my class I made.

 

@ironicflunky541 Did you copy and paste the code? Because I don't see a package statement.

 

How many classes do you have? Are you sure that's the main class?

 

If you have more than 1 class you need a class to register the rest that is what you put there.
