Solved Plugin prints command as message

@Konato_K
Yes, it terminates it if the thrown exception is not handled. Thus, it prevents your plugin from breaking, by halting the execution in case the exception is not handled.

 

@ShowbizLocket61 I'm not entirely sure if halting execution can be considered "prevent from breaking", technically it breaks it, in some way

 

The plugin works beautiously now, and I shall post the code here so that it might help someone else later. I don't know if there's anything else I should change. I know I could check for length of args, but seeing as this is all I wanted out of the plugin, I think I'll leave it as-is.

Main class (open) Main class (close)

Code:

package me.blue1.skyemusic;

import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.plugin.java.JavaPlugin;

import me.blue1.skyemusic.cmds.Music;

public class Main extends JavaPlugin{
    @Override
    public void onEnable(){
        Bukkit.getConsoleSender().sendMessage(ChatColor.GREEN+"Music has been Enabled successfully");
        getCommand("play").setExecutor(new Music());
        getCommand("sm").setExecutor(new Music());
        getCommand("skyemusic").setExecutor(new Music());
    }
}

Music Class (open) Music Class (close)

Code:

package me.blue1.skyemusic.cmds;

        Player p = (Player) sender;
        String prefix = new String(ChatColor.GRAY+"["+ChatColor.DARK_AQUA+"Music"+ChatColor.GRAY+"] ");
        if(cmd.getName().equalsIgnoreCase("play")){

Hope this helps someone. If there's something I can do to improve it, let me know. If I should add this as a plugin of mine to be downloaded, also let me know.
