shceduled task not working?

So i made a scheduled task to make like a countdown , but doesnt seem to work:

EDIT: i even added a debug message in the shceduled task , but is not printing

EDIT 2 : so im an idiot , the dbug message is in the wrong place, the scheduled task is firing correctly , its like there is nothing storing inot the map . I added the code from the class where the clock is getting the map.

PHP:

public class Clock {
 
    public Clock() {
     
    }
 
    DrinkPotion drink = new DrinkPotion();
 
 
    public void startClock() {
     
        Bukkit.getScheduler().scheduleSyncRepeatingTask(Bukkit.getPluginManager().getPlugin("Vuelta"), new Runnable() {
         
         
            public void run() {
             
                for(Entry<Player, Integer> map : drink.count.entrySet()) {
                    System.out.println("debug");
                 
                 
                    Player player = map.getKey();
                    int sec = map.getValue();
                 
                 
                    sec--;
                 
                    drink.count.put(player, sec);
                 
                    if(sec == 0) {
                        drink.count.remove(player);
                        player.sendMessage("has sido eliminado de la lista");
                    }
                 
                 
                 
                }
             
            }
         
         
        }, 0L, 20);
     
     
    }

}

PHP:

public class Main extends JavaPlugin {
 
    Frases frases = new Frases();
    Items itemsInstance = new Items();
    Clock clock = new Clock();

 
 
    @Override
 
    public void onEnable() {
 
        CommandSender console = Bukkit.getConsoleSender();
     
        console.sendMessage(frases.PLUGIN_PREFIX + "Plugin enabled correctly");
     
        clock.startClock();
        registerCommands();
        registerEvents();
        registerItems();
     
     
     
     
    }
 
 
 
    @Override
 
    public void onDisable() {
     
        CommandSender console = Bukkit.getConsoleSender();
     
        console.sendMessage(frases.PLUGIN_PREFIX + "Plugin disabled correctly");
    }
 
 
    private void registerCommands() {
     
     
     
    }
 
 
    private void registerEvents() {
        Bukkit.getPluginManager().registerEvents(new DrinkPotion(), this);
     
    }
 
    private void registerItems() {
        itemsInstance.waterWalk();
     
    }

PHP:

public class DrinkPotion implements Listener {
   
    public DrinkPotion() {
       
    }
   
    HashMap<Player, Integer> count = new HashMap<Player, Integer>();
   
    Items items = new Items();
   
    @EventHandler
   
    public void onPotionDrink(PlayerItemConsumeEvent e) {
        System.out.println("consumed item");
       
        Player player = e.getPlayer();
       
        ItemStack item = e.getItem();
        ItemMeta meta = item.getItemMeta();
       
        if(item!=null) {
            if(meta!=null) {
                if(meta.getDisplayName()!=null) {
                   
                    if(meta.getDisplayName().equalsIgnoreCase(ChatColor.DARK_PURPLE + "ICE WALKER")) {
                        count.put(player, 30);
                        player.sendMessage("added to list");
                    }
                   
                   
                   
                }
            } 
           
        }
           
               
           
       
       
       
       
       
       
    }

}

 

You're creating a new DrinkPotion instance in the Clock class then iterating over it. If you just created it, and I don't see anywhere you set data to it, I assume it's empty so of course nothing will happen when your runnable iterates it. I don't see the field being public or having a setter, so how do you plan to populate it?

Also you don't need to get the console sender to send messages in onEnable; use the logger that's what it is there for. e.g. getLogger().info("blah blah"); That said, sending a "plugin enable" message is just pointless spam as Spigot already sends messages upon enable/disable.
