NullPointerExeption

I get a:
at me.mrgermanrain.main.Main.onEnable(Main.java:17)

Code:java

 public void onEnable(){ //16
this.getCommand("ctf").setExecutor(new Command_YT()); //17
this.getCommand("infamyctf").setExecutor(new Command_YT()); //18
System.out.println(this.getDescription().getName() + "has been successfully activated "+ this.getDescription().getVersion()); //19
}

 

Can we see the full Main class, a stacktrace, and the Command_YT class?

Command_YT:

Code:java

package Commands;
 
import java.io.IOException;
 
 
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.command.ConsoleCommandSender;
import org.bukkit.configuration.InvalidConfigurationException;
import org.bukkit.entity.Player;
 
public class Command_YT implements CommandExecutor {
 
@Override
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
 
if(sender instanceof ConsoleCommandSender){
System.out.println("This command is only for players");
return true;
}
Player p = (Player) sender;
 
if(args.length == 0){
if(p.hasPermission("ctf.admin")){
Funktionen.sendAdminMenu(p);
}else{
Funktionen.sendMenu(p);
}
 
}else if(args.length == 1){
if(args[0].equalsIgnoreCase("leave")){
Funktionen.leaveArena(p);
}else{
Funktionen.sendMenu(p);
}
}else if(args.length == 2){
 
if(args[0].equalsIgnoreCase("create")){
Funktionen.checkPermission(p);
String ArenaName = args[1];
try {
Funktionen.createArena(p, ArenaName);
} catch (IOException e) {
e.printStackTrace();
}
}else if(args[0].equalsIgnoreCase("delete")){
Funktionen.checkPermission(p);
Funktionen.delArena(p, args[1]);
}else if(args[0].equalsIgnoreCase("join")){
try {
Funktionen.joinArena(p, args[1]);
} catch (IOException| InvalidConfigurationException e) {
e.printStackTrace();
}
}
}
return true;
}
}
 

Main:

Code:java

package me.razorblur.main;
 
import java.util.ArrayList;
 
import org.bukkit.configuration.file.FileConfiguration;
import org.bukkit.plugin.java.JavaPlugin;
 
import Commands.Command_YT;
 
public class Main extends JavaPlugin {
 
public static String pluginName = "§4[InfamyCTF]§b";
public static ArrayList<String> inGamePlayers = new ArrayList<>();
public static int PlayerAmount = 0;
 
public void onEnable(){
this.getCommand("ctf").setExecutor(new Command_YT());
this.getCommand("infamyctf").setExecutor(new Command_YT());
System.out.println(this.getDescription().getName() + "has been successfully activated "+ this.getDescription().getVersion());
}
 
public void onDisable(){
System.out.println(this.getDescription().getName() + "has successfully deactivated "+ this.getDescription().getVersion());
}
 
 
public void loadConfig(){
FileConfiguration cfg = this.getConfig();
cfg.options().copyDefaults(true);
 
}
}
 

 

Code:

this.getCommand("ctf").setExecutor(new Command_YT())

Instead of this, try:

Code:

getCommand("ctf").setExecutor(new Command_YT())

And can you provide a full stacktrace?

 

Same error xTigerRebornx

 

MrGermanrain
Try removing the System.out.println

 

same error

 

MrGermanrain I need a FULL stack trace, not just that tiny 1 line error

 

MrGermanrain
Can I see your plugin.yml?

 

xTrollxDudex I think you might find it hard to solve an error when he doesn't say what it is.... XD

 

xTigerRebornx
You can kinda see:

Errors like that aren't usually gonna happen, based off deduction, you can have a pretty good idea that this is going on:

As you can see, it says:

This is what I believe is happening.

 

xTrollxDudex Eh, its 12AM (really late) here, not in the mood for deep thinking XD
His plugin.yml would be nice too see

Plugin.yml

MrGermanrain Can we get a full stacktrace?

MrGermanrain I am not sure what the problem might be, but instead of using system.out.printLn, use Bukkits logger.

 

I have tried that.

 

I would try getting rid of all the getDescription calls. If that fixes it, then I'm guessing the problem is in your plugin.yml file somewhere.

EDIT: or maybe not, if line 17 in your code matches up to what you pasted... Then I'm at a loss.

 

MrGermanrain I have had that error before, it is usually caused by improper formatting of the plugin.yml. Make sure you use spaces instead of tabs, and that you don't have any extra spaces, as I can't see anything particularly wrong with it.

 

MrGermanrain
Wait, you didn't even check if cmd.getName().equalsIgnoreCase("ctf") in your CommandExecutor....

And also, there are 3 senders of commands: CONSOLE, PLAYER, and COMMAND_BLOCK. Just do

PHP:

if(!(sender instanceof Player))

And escape the method with return.

 

xTrollxDudex Lol you're right. xD
