package com.bwfcwalshy.plmsg;
 
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
 
public class Plugin implements CommandExecutor {
 
    public Main plugin;
 
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        Player player = (Player) sender;
        if(cmd.getName().equalsIgnoreCase("plugin") || cmd.getName().equalsIgnoreCase("plugins") || cmd.getName().equalsIgnoreCase("pl") || cmd.getName().equalsIgnoreCase("version")){
                sender.sendMessage(plugin.getConfig().getString("Message").replaceAll("&", "§"));
        }
        return false;
    }
}
 

 

Line 10: plugin is null since you never initialized it.

 

By the beginning, you should add return true at the end of the command statement!
The error is thrown at this line:

Code:

    sender.sendMessage(plugin.getConfig().getString("Message").replaceAll("&", "§"));

And it's a NullPointerException. That means that sender or plugin point nothing.
I think it's plugin.

You should do the following:

Add the object statement of your class Plugin and when you call it into the main class, add the argument "this".

e.g.:

Code:java

Plugin plugin;
public Plugin(JavaPlugin plugin) {
this.plugin = plugin;
}

 

bwfcwalshy

onEnable() method?

 

JEREMSPEED remove that static field please

 

Your class is named Plugin. The same as Plugin.class in the bukkit API. Check if the problems come from this.
