[Help] My bucket scheduler won't work!

Hey there, I am trying to make a simple Bukkit scheduler but I keep getting a error and I don't know how to fix it.

My whole Bukkit Scheduler:

                BukkitScheduler scheduler = Bukkit.getServer().getScheduler();

                scheduler.scheduleSyncDelayedTask((Plugin) this, new Runnable() {

                  public void run(){

                }, 1200L);

Thanks for any help I get!

 

Ok, i have done what you have said but now it is saying I have a error on this line in my main class:

Code (Text):

 
public class Core extends JavaPlugin implements Listener{

Do I need to extend and implement anything else?

 

Ok, I have this in my villager class:

Code (Text):

 scheduler.scheduleSyncDelayedTask((Plugin) new Core(), new Runnable() {

And I have a error saying:

The line of code it is saying the error is on it this:

Code (Text):

 public class Core extends JavaPlugin implements Listener{

I don't know what is wrong.

 

I have never really worked with runnable's so the answer is probably a no.

 

Ok, this is my main class:

Code (Text):

 
package me.bradley.ranks;



import org.bukkit.event.Listener;

import org.bukkit.plugin.java.JavaPlugin;



public class Core extends JavaPlugin implements Listener{

   

    public void onEnable(){

        getServer().getPluginManager().registerEvents(new Villager(), this);

        getCommand("villager").setExecutor(new Villager());

    }

   

    public void onDisable(){

       

    }



}

This is my villager class. There are probably many things in there you all don't like but it all works apart from the scheduler:
