Making a nickname plugin but i get errors

I get those things https://gyazo.com/d4cb7d9d1627664d5a64994edf446a38 and i cant fix it

Code:

import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.permissions.Permission;
import org.bukkit.plugin.PluginDescriptionFile;
import org.bukkit.plugin.PluginManager;
import org.bukkit.plugin.java.JavaPlugin;

public class Plugin1 extends JavaPlugin {
    public final Logger logger = Logger.getLogger("Minecraft");
    public Permission playerPermission = new Permission("Sillynicks.set");
    @Override
    public void onEnable() {
        PluginDescriptionFile pdf = this.getDescription();
        this.logger.info(pdf.getName() + " Is now enabled");
        saveConfig();
        PluginManager pm = getServer().getPluginManager();
        pm.addPermission(playerPermission);
    }
  
    @Override
    public void onDisable() {
        PluginDescriptionFile pdf = this.getDescription();
        this.getLogger().info(pdf.getName() + " Is now disabled");
        saveConfig();
      
    }
    @EventHandler
    public void onPlayerJoin(PlayerJoinEvent e){
        Player p = e.getPlayer();
        if(!p.hasPlayedBefore()){
            getServer().broadcastMessage(ChatColor.AQUA + p.getName() + ChatColor.DARK_AQUA + "has entered the best server!");
        }
    }

    @Override
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
        if (sender instanceof Player){
            Player p = (Player)sender;
            if(args.length==2){
                String name = args[0];
                String newname = args[1];
                for(Player pl : getServer().getOnlinePlayers()){
                    if(pl.getName().equals(name)){
                        if(getServer().getPlayer(name).isOp()||getServer().getPlayer(name).hasPermission("Sillynicks.set"))
                        getServer().getPlayer(name).setDisplayName(newname);
                    }
                }
            }
      
            return true;
       
        }
  
        return false;
    }  
  
}

 

*facepalm*
That is not an error. That is just the IDE warning you about something. Maybe you should read what that warning is about.

 

A wild BCBroz Watcher has appeared!


@SillySAKE
You're code is filled with outdated and bad practices. Fun facts:

• Bukkit displays enable/disable messages
• Every plugin has its own logger
• A plugins's name can be accessed from within the main class

Anyway, a small picture of a method call does not show us where the error is, on what line in the above code is the error?

EDIT: For sake of teej:

Code:

Post post = this.getContainer();
String text = post.getText().replaceAll("error", "warning");
post.setText(text);
post.update();

 

Oh yeah. That reminds me.

@SillySAKE You should read this: https://bukkit.org/threads/new-devs-how-to-make-your-plugin-right-make-it-better.317054/

EDIT: @meguy26 I actually took a closer look at his code. I don't think its from BCBlowz or else it'll be worse.

 

So all of this is outdated
i should rewrite the code?

 

@SillySAKE That would be a good idea yes, and maybe follow a tutorial (not TheBCBroz though).

 

@SillySAKE
Probably the best beginner tutorial out there is http://wiki.bukkit.org/Plugin_Tutorial, I mean, it is the official wiki one.

 

The thing is what ever i do i got tons of errors in my console and i don't know why
i tried rewriting the plugin in a different way it still doesn't work

 

i get this: pastebin.com/wnx0VpXV

 

Nvm i got it to work i rewrote it again but now it works
Only prob now is i need to add the color codes
and i have no clue how? lol noob

 

@SillySAKE
In messages:
ChatColor.<COLOR>

In a config:
coloured-message: '&aThis is coloured'
ChatColor.translateAlternateColorCodes('&', getConfig.getString("coloured-message");

 

(colored-message: '&aThis is colored') is that necessary?
and ("coloured-message"); what it the couloured message suppose to be

 

@SillySAKE It's not necessary, that's just an example. Make it whatever you want and in the ChatColor method make it whatever your config string is.

 

Can you help because the getConfig doesnt work
This is what i got now:

Code:

import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.permissions.Permission;
import org.bukkit.plugin.PluginManager;
import org.bukkit.plugin.java.JavaPlugin;

public class SillyNicnames extends JavaPlugin {
   @Override
   public void onEnable() {
     getLogger().info("onEnable has been invoked!");
     PluginManager pm = getServer().getPluginManager();
     pm.addPermission(playerPermission);
   }
   @Override
   public void onDisable() {
     getLogger().info("onDisable has been invoked!");
   }
   public Permission playerPermission = new Permission("nickname.set");
   @Override
   public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
     if (cmd.getName().equalsIgnoreCase("nickname") && sender instanceof Player) {
       Player player = (Player) sender;
       if(player.isOp() || player.hasPermission("nickname.set")){
         if(args.length==1);
         String name = args[0];
         ChatColor.translateAlternateColorCodes('&', getConfig.getString(name));
         player.setCustomName(name);
         player.setDisplayName(name);
         player.sendMessage(ChatColor.GOLD + "Your Nickname has changed");
           }else{
      player.sendMessage(ChatColor.DARK_RED + "You do not have permission to use this command!");
           }
    }  return true;  
 }
}
