Code:

        p.setScoreboard(board);
    }
    public void onPlayerDeath(PlayerDeathEvent e){
        Player dead = e.getEntity().getPlayer();
        Player Killer = e.getEntity().getKiller();
       
        deaths.put(dead.getName(), deaths.get(dead.getName())+ 1);
        if(e.getEntity().getKiller() instanceof Player){
            kills.put(Killer.getName(), kills.get(Killer.getName())+ 1);
        }
           
    }
}

The only thing i noticed, it that the scoreboard is not showing up...

 

Don't steal minecrafts logger! Use getLogger() instead.

Stick to naming conventioins: The main class should be your plugins name, and it should start with a n Uppercase letter.

If they are unused, delete them.

The onEnabled is called well before any player can join. This will almost always be null.

Don't log your own plugins. Bukkit does this for you.

You are forgetting the @EventHandler tags.
