Could not pass event PlayerLoginEvent

Hello guys,
I'm trying to open an inventory to enter the server, but is not working, what is my mistake?

Code:

my code:

Code:

package me.champs.bukkit;
import java.util.logging.Level;
import org.bukkit.Bukkit;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerLoginEvent;
import org.bukkit.inventory.Inventory;
import org.bukkit.plugin.java.JavaPlugin;
public class PluginLogin extends JavaPlugin implements Listener {
  @Override
  public void onEnable() {
  getServer().getPluginManager().registerEvents(this, this);
  }
  @EventHandler
  public void onLogin(PlayerLoginEvent event) {
  getLogger().log(Level.INFO, "Player " + event.getPlayer().getName() + " is logging in!");
  Inventory inv = Bukkit.createInventory(null,9,"Welcome");
  Player p = event.getPlayer();
  p.openInventory(inv);
  }
}

 

LoginEvent is casted before a player actually logs in. Delay the task by a tick and it should work ok.

 

As has been said before, use "PlayerJoinEvent" instead of login to fix this issue.

You should follow the format "me.<your name>. <project name>". Just adding "Bukkit" to the end may cause conflicts in the future.

 

Ok, thanks, worked
