    @NoU_X2 You have a constructor don't you?
    If so: remove it.

    I'm fairly new to this stuff but can you please tell me which of these are the constructors and i will remove it ASAP
    Code:
    package me.NoU_x2.Li8ghtningRod;
    
    import javax.annotation.Nonnull;
    
    import org.bukkit.Location;
    import org.bukkit.Material;
    import org.bukkit.entity.Player;
    import org.bukkit.event.EventHandler;
    import org.bukkit.event.player.PlayerInteractEvent;
    import org.bukkit.plugin.java.JavaPlugin;
    import io.netty.handler.codec.http2.Http2Connection.Listener;
    
    public abstract class Main extends JavaPlugin implements Listener{
      
        public void onEnable() {
            getServer().getPluginManager().registerEvents((org.bukkit.event.@Nonnull Listener)this, this);
        }
      
        @SuppressWarnings("deprecation")
        @EventHandler
        public void onPlayerInteract(PlayerInteractEvent event) {
            Player player = event.getPlayer();
            if (player.getItemInHand().getType() == Material.STICK) {
                player.getWorld().strikeLightning((@Nonnull Location) player.getTargetBlock(null, 200));
            }
        }
      
    }

    I have done it but its still saying the same thing. Abnormal plugin type, is there anything else to remove?

    @NoU_X2 Shouldn't you implement 'org.bukkit.event.Listener' in stead of 'io.netty.handler.codec.http2.Http2Connection.Listener'?

    I have replaced it now, thank you for your help but it didn't fix anything for all I know.

    @NoU_X2 Should not need this: "
    (org.bukkit.event.@Nonnull Listener"

    Yup I have removed that and this is what I have currently. Still for some reason came up with the same message
    Code:
    
    package me.NoU_x2.Li8ghtningRod;
    
    import org.bukkit.Material;
    import org.bukkit.entity.Player;
    import org.bukkit.event.EventHandler;
    import org.bukkit.event.player.PlayerInteractEvent;
    import org.bukkit.plugin.java.JavaPlugin;
    import org.bukkit.event.Listener;
    
    public class Main extends JavaPlugin implements Listener{
       
        public void onEnable() {
            getServer().getPluginManager().registerEvents(this, this);
        }
       
        @SuppressWarnings("deprecation")
        @EventHandler
        public void onPlayerInteract(PlayerInteractEvent event) {
            Player player = event.getPlayer();
            if (player.getItemInHand().getType() == Material.STICK) {
                player.getWorld().strikeLightning(player.getTargetBlock(null, 200).getLocation());
            }
        }
       
    }

    @NoU_X2 Please make sure that you are actually updating the correct jar.
    That error should be changing.

    I have been updating the correct jar. I even went into the server and typed /plugins and I couldn't see my plugin on the list at all

    EDIT
    Nevermind It works now. There was another .jar in my left hand thing they had old things on it and all I had to do was remove em. Thanks for your help guys!!!!!

    EDIT by Moderator: merged posts, please use the edit button instead of double posting.
