Solved java.lang.IllegalArgumentException cannot set to an empty path

Hello, I was trying to configure my config and it seems to not work anymore. It is a simple new join message, with a command which allows people to see the new join message, if they are not new players (for testing purposes).




This is the error the console gives,

Code:

INFO New Join MSG: Visit mc.beyondhorizonmc.net for support
27.05 19:55:35 [Server] ERROR Error occurred while enabling newjoinmessage v1.0 (Is it up to date?)

This is my plugin class note I have // some stuff to try to troubleshoot and its still not working...

Code:

package me.myip.newjoinmessage;
//imports craftbukkit for usage, this will allways be needed
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.configuration.file.FileConfiguration;
import org.bukkit.entity.Player;
import org.bukkit.event.Event;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.plugin.java.JavaPlugin;
public class newjoinmessage extends JavaPlugin implements Listener {

//All stuff I forgot
FileConfiguration config = getConfig();
 
    public void onEnable(){
        //getServer().getLogger().info("New Join MSG: Visit mc.beyondhorizonmc.net for support");
     
        //default string for new join message
        String newjoinmessage = "";
     
        //creates a config file, sets a default line of text for the config file.
        config.set(newjoinmessage, "Configure");
        config.options().copyDefaults(true);
        saveConfig();
        //checking for new people
        getServer().getPluginManager().registerEvents(this, this);
    }
    public void onDisable(){
        getServer().getLogger().info("New Join MSG Disabled");
    }
//MAIN BODY OF PLUGIN 
 
    @EventHandler
public void onPlayerJoin(PlayerJoinEvent event){
        Player player = event.getPlayer();
    if (config.getBoolean("Welcome to the Server, visit mc.beyondhorizonmc.net for help")){
            player.sendMessage("Welcome to the Server, visit mc.beyondhorizonmc.net for help ");
 
    }else {
     
    }
 
 
 
    }
 
 
 
 
 
 
 
    @EventHandler
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] arguments){
        // /help label would - help argument would be empty list
        if (cmd.getName().equalsIgnoreCase("newjoinmessage")){
        //    config.getString("newjoinmessage");
        //    sender.sendMessage("newjoinmessage");
            //below may need to be returned false as it will send a player a default message, stating cmd
            return true;
        }
     
        return false;
    }
}
//:
//;

This is my plugin.yml

Code:

main: me.myip.newjoinmessage.newjoinmessage
name: newjoinmessage
version: 1.0
author: James
description: Custom New Join Message
commands:
   newjoinmessage:
      description: This retreives the default new join message.
      usage: /newjoinmessage [player]
      permission: newjoinmessage.newjoinmessage
      permission-message: You don't have <permission>

Any help would be much appreciated. Additonally i have tried google however, all posts using the 2nd line of the error code relate to other problems.

 

@14manj01
newJoinmessage is empty. It needs to be equal to a string with atleast one character.

 

Take a look at this video:

It kinda does the same as you want! Just change couple of stuff

 

Also I figured out it was in part to the plugin.yml not having the correct setup for commands.
