Solved Not extending to JavaPlugin?

Im making a plugin rightnow for some unrealesed server, and part of it is the shop. Now I am good with the shop, but for some reason the extend to Java Plugin is underlined in red, which means the plugin wont work. Any help on hoe to fix this?

Code:

package Commands;

import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.Material;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.inventory.Inventory;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.meta.ItemMeta;
import org.bukkit.plugin.java.JavaPlugin;

public class OpenShop extends JavaPlugin ;
{ 
public boolean onCommand(CommandSender theSender, Command cmd, String commandLabel, String[] args)
{
    if(commandLabel.equalsIgnoreCase("shop"))
    {
        Player player = (Player) theSender;
        {
        private void openGUI (Player player)
        {
            Inventory inv = Bukkit.createInventory(null, 18, ChatColor.GOLD + "Shop");
           
            ItemStack ores = new ItemStack(Material.IRON_INGOT);
            ItemMeta oresMeta = ores.getItemMeta();

 

oh, didnt notice that. Probably typed it without thinking.

THanks
