Need to import my plugin in my subclass.

This is my class where i want to import the config file.

Code:

package me.lars110304.attractie.commands.subcommands;

import me.lars110304.attractie.Attractie;
import me.lars110304.attractie.commands.SubCommand;
import org.bukkit.Location;
import org.bukkit.Sound;
import org.bukkit.configuration.file.FileConfiguration;
import org.bukkit.entity.Player;

public class CreateCommand extends SubCommand {

    @Override
    public String getName() {
        return "create";
    }

    @Override
    public String getDescription() {
        return "Create a attraction.";
    }

    @Override
    public String getSyntax() {
        return "/attraction create <Name>";
    }


    @Override
    public void perform(Player p, String[] args, Attractie plugin) {
        if (args.length == 2){
            Location l = p.getLocation();
            plugin.getConfig().createSection("savedlocations." + args[1]);
            plugin.getConfig().set("savedlocations." + args[1] + ".x", l.getX());
            plugin.getConfig().set("savedlocations." + args[1] + ".y", l.getY());
            plugin.getConfig().set("savedlocations." + args[1] + ".z", l.getZ());
            plugin.getConfig().set("savedlocations." + args[1] + ".pitch", l.getPitch());
            plugin.getConfig().set("savedlocations." + args[1] + ".yaw", l.getYaw());
            plugin.saveConfig();
            p.playSound(p.getLocation(), Sound.ENTITY_PLAYER_LEVELUP, 1, 1);
            p.sendMessage("§aYou succesfully created a attraction named: §6" + args[1]);


        } else if(args.length != 2){
           p.sendMessage("§c§lError: §aDo it like this: §6/attraction create <name>");
        }

    }
}

This is my Command manager.

Code:

package me.lars110304.attractie.commands;

import me.lars110304.attractie.Attractie;
import me.lars110304.attractie.commands.subcommands.CreateCommand;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;

import java.util.ArrayList;


public class CommandManager implements CommandExecutor {

    private final ArrayList<SubCommand> subCommands = new ArrayList<>();

    public CommandManager() {
        subCommands.add(new CreateCommand());
    }
    Attractie plugin;

    public CommandManager(Attractie instance){
        plugin = instance;
    }



    @Override
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {

        if(sender instanceof Player) {
            Player p = (Player) sender;
            if(command.getName().equalsIgnoreCase("attraction")) {
                if (args.length > 0) {
                    for (int i = 0; i < getSubcommands().size(); i++) {
                        if (args[0].equalsIgnoreCase(getSubcommands().get(i).getName())) {
                            getSubcommands().get(i).perform(p, args, plugin);
                        }
                    }

                } else if (args.length == 0) {
                    p.sendMessage("§cEnter some arguments");
                }
            }
        }
        return true;
    }
 
    public ArrayList<SubCommand> getSubcommands(){
        return subCommands;
    }
}

this is my main.

Code:

package me.lars110304.attractie;

import me.lars110304.attractie.commands.CommandManager;
import org.bukkit.configuration.file.FileConfiguration;
import org.bukkit.plugin.java.JavaPlugin;

public final class Attractie extends JavaPlugin {

    @Override
    public void onEnable() {
        // Plugin startup logic
        getConfig().options().copyDefaults();
        saveDefaultConfig();
        getCommand("attraction").setExecutor(new CommandManager());
    }



    @Override
    public void onDisable() {

        // Plugin shutdown logic
    }
}

this is the error

@Lars110304

Youneed to choose a constructor to use or call this() in your constructor with arguments for call the one without argument then pass your main class as parameter
