Selbst programmiertes MC Plugin Variable existiert nicht obwohl ich sie davor benutzt habe?

Das ist der Code der Main.java Datei:

package easytrade.thepixel3261.easytrade;

import org.bukkit.Material;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.inventory.ItemStack;
import org.bukkit.plugin.java.JavaPlugin;

public class Main extends JavaPlugin implements CommandExecutor{


    @Override
    public void onEnable() {
        getLogger().info("Plugin enabled!");
    }

    @Override
    public void onDisable() {
        getLogger().info("Plugin disabled!");
    }

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if (cmd.getName().equalsIgnoreCase("convert")) {
            if (!(sender instanceof Player)) {
                sender.sendMessage("Only players can use this command.");
                return true;
            }

            Player player = (Player) sender;

            if (args.length != 2) {
                player.sendMessage("Usage: /convert <material> <amount>");
                return true;
            }

            Material fromMaterial = Material.getMaterial(args[0].toUpperCase());
            int amount = Integer.parseInt(args[1]);

            if (fromMaterial == null) {
                player.sendMessage("Invalid material specified.");
                return true;
            }

            Material toMaterial = null;

            if (fromMaterial == Material.COPPER_INGOT && amount >= 2) {
                toMaterial = Material.EMERALD;
                amount /= 2;
            } else if (fromMaterial == Material.EMERALD && amount >= 1) {
                toMaterial = Material.COPPER_INGOT;
                amount *= 2;
            } else {
                player.sendMessage("Invalid material specified or not enough items.");
                return true;
            }

            ItemStack fromItem = new ItemStack(fromMaterial, amount);

            if (!player.getInventory().containsAtLeast(fromItem, amount)) {
                player.sendMessage("You do not have enough " + fromMaterial.toString().toLowerCase() + "s in your inventory.");
                return true;
            }

            if(toMaterial == Material.EMERALD) {
                ItemStack toItem = new ItemStack(toMaterial, amount/2);
            }
            if(toMaterial == Material.COPPER_INGOT) {
                ItemStack toItem = new ItemStack(toMaterial, amount*2);
            }

            // Remove the specified number of items from the player's inventory
            player.getInventory().removeItem(fromItem);

            // Add the converted items to the player's inventory
            player.getInventory().addItem(toItem);

            player.sendMessage("Successfully converted " + amount + " " + fromMaterial.toString().toLowerCase() + "s to " + amount + " " + toMaterial.toString().toLowerCase() + "s.");

            return true;
        }

        return false;
    }
}

Als Server Software benutze ich Spigot. Das ist der Code der Main.java Datei:

        getLogger().info("Plugin disabled!");
    }

    @Override

                return true;
            }

            Player player = (Player) sender;

            if (args.length != 2) {
