    Hello there!
    I'm trying real hard to set up a countdown mechanism.
    But for some reason i keep getting the same annoying error message no matter what i do.
    This is what the class file looks like:
    Code:java
    1.  
    2.     import org.bukkit.Bukkit;
    3.     import org.bukkit.event.EventHandler;
    4.     import org.bukkit.event.Listener;
    5.     import org.bukkit.event.player.PlayerJoinEvent;
    6.     import org.bukkit.plugin.java.JavaPlugin;
    7.  
    8.     public class Countdown extends JavaPlugin implements Listener {
    9.  
    10.             int seconds = 60;
    11.  
    12.             private void Lobby() {
    13.                     Bukkit.getServer().getScheduler()
    14.                                     .scheduleSyncRepeatingTask(this, new Runnable() {
    15.                                             public void run() {
    16.                                                     if (seconds == 60) {
    17.                                                             Bukkit.broadcastMessage("Starting in 60 secs!");
    18.                                                     } else if (seconds == 30) {
    19.                                                             Bukkit.broadcastMessage("Starting in 30 secs!");
    20.                                                     } else if (seconds == 15) {
    21.                                                             Bukkit.broadcastMessage("Starting in 15 secs!");
    22.                                                     } else if (seconds == 10) {
    23.                                                             Bukkit.broadcastMessage("Starting in 10 secs!");
    24.                                                     } else if (seconds <= 10 && seconds > 0) {
    25.                                                             Bukkit.broadcastMessage("Starting in " + seconds
    26.                                                                             + " secs!");
    27.                                                     } else if (seconds == 0) {
    28.                                                             Bukkit.broadcastMessage("Starting now!");
    29.                                                     }
    30.                                                     if (seconds == -100) {
    31.                                                             seconds = -1;
    32.                                                     }
    33.                                             }
    34.                                     }, 0, 20);
    35.             }
    36.  
    37.             @EventHandler
    38.             void Join(PlayerJoinEvent event) {
    39.                     Lobby();
    40.             }
    41.     }
    42.  

    To me this seems perfect :(
    Don't question that it doesn't make sense and wont be a proper working mechanism for a minigame server. I know that. For now I'm just trying real hard to get the countdown to work.
    But i keep getting the following error message everytime a player joins:
    Code:java
    1.  
    2.

    This is line 15: Bukkit.getServer().getScheduler().scheduleSyncRepeatingTask(this, new Runnable() {
    This is line 43: Lobby();

    Thank you so much for helping me!

    Fedmand Put it in your onEnable() method, you are scheduling a task before you can even enable the plugin

    EDIT: You aren't registering your listeners either
