Bukkit Scheduler not working?

Heres my code:

Code:java

@EventHandler(priority=EventPriority.HIGH)
  public void onBlockPlace(BlockPlaceEvent e) {
    final Player p = e.getPlayer();
    final Block b = (Block) e.getBlockPlaced();
    if (b.getType() == Material.REDSTONE_TORCH_ON) {
      p.sendMessage("§a§lSupply crate dropped!");
      FallingBlock block = e.getPlayer().getWorld().spawnFallingBlock(e.getBlockPlaced().getLocation().add(0, 20, 0), Material.PISTON_BASE, (byte)6);
      final Block crate = (Block) block;
      float x = 0.1F;
      float y = 1.0F;
      float z = 0.1F;
      block.setVelocity(new Vector(x, y, z));
      Bukkit.getServer().getScheduler().scheduleSyncDelayedTask(this, new Runnable() {
 
        @Override
        public void run() {
            p.sendMessage("Test!");
        }
        }, 100);
 
      }
 
  }
 

Everything works, except the Test message. Why isn't it working?

 

If you're sure that it didn't happen after 5 seconds, you should store their UUID and look the player up again after 5 seconds.

 

Its not that send message isn't working, it's the task. I tried using other things in it, but nothing works.

 

It can actually be stored just fine.

BetaNyan Why are you using Bukkit.getServer().getScheduler()?

Code:java

Bukkit.getScheduler().scheduleSyncDelayedTask(plugin, new Runnable(){
    public void run(){
        // your code
    }
}, delay);

 

What I would do is just initiate a new BukkitRunnable
'new BukkitRunnable' and then go on from there.
