这是密码。没有警告，config.yml文件正常。

            }else if(args.length == 1){
                Player targetPlayer = player.getServer().getPlayer(UUID.fromString(args[0]));
                Location location = targetPlayer.getLocation();
                player.teleport(location);
                player.sendMessage(ChatColor.DARK_AQUA + "Teleportation commensing... ");

        }
        return false;
    }
}

将plugin.yml文件中的main:键设置为包括包在内的主类的全名。

主：me.roofer.rteleport.rteleport

我建议您遵循命名惯例，将包用小写字母表示。
