Having problems with events

Hello guys so I just started out and tried to make a join message plugin but it doesnt work idk why. This is my code:

main:

Code:

package me.Rokas.JoinMessage;

import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.plugin.PluginManager;
import org.bukkit.plugin.java.JavaPlugin;

public class JoinMessage extends JavaPlugin implements Listener {
  
    public void OnEnable() {
        registerEvents();
    }
  
    public void OnDisable() {
      
    }
    public void registerEvents() {
        PluginManager pm = getServer().getPluginManager();
      
        pm.registerEvents(this , this);
    }
    @EventHandler
    public void onPlayerJoinEvent(PlayerJoinEvent event) {
        Player player = event.getPlayer();
        player.sendMessage("Hello");
      
    }
}

my plugin.yml

Code:

name: JoinMessage
main: me.Rokas.JoinMessage.JoinMessage
version: 1.0
description: A plugin that help with chat and messages
author: Rokas

idk maybe i did't export it right

 

The OnEnable should start with lowercase same goes with OnDisable.

onEnable and onDisable.

 

@Th3Rokaz
Do as @JanTuck recommend, and also refactor your package. Package names should be all lowercase.

 

Thank you guys
