Help with my plugin

Hey! I literally just started coding plugins today, following Kyeg's very helpful tutorial. It all seemed to be going well, but when I put the plugin in plugins and reloaded the server, it displayed quite a lot of error messages and I don't know what any of them mean! Plus, the plugin isn't even in the plugins list so it must have gone really wrong :"D Can someone shed some light?
Here is my error message:
[14:08:37] [Server thread/CRITICAL]: #3 pmsrc/src/pocketmine/plugin/PluginManager(238): FolderPluginLoader\FolderPluginLoader->getPluginDescription(string[30] /opt/service/plugins/lanternMC)
[14:08:37] [Server thread/CRITICAL]: #4 plugins/PocketMine-DevTools.phar/src/DevTools/DevTools(69): pocketmine\plugin\PluginManager->loadPlugins(string[21] /opt/service/plugins/, array[1])

[14:08:37] [Server thread/CRITICAL]: #11 pmsrc/src/pocketmine/PocketMine(321): pocketmine\server()
And here is my code:
<?php

namespace LanternServer\lanternMC

use pocketmine\plugin\PluginBase
use pocketmine\plugin\commandSender
use pocketmine\command\Command;

class Main extends PluginBase {

public function onEnable() {
$this->getServer()->getLogger()->info("[LanternMC custom plugin enabled!]")
}

public function onDisable() {
$this->getServer()->getLogger()->info("[LanternMC custom plugin disabled..]")
}

public function onCommand(commandSender $sender, Command $command, string $label, array $args) : bool {
switch ($command->getName()) {
case "lanternMC":
$sender->sendMessage("[§6Lantern§4MC]§rWelcome to §6Lantern§4MC§r!");
}
return true;
}

}

 

PHP is case-sensitive.
Change use pocketmine\plugin\commandSender to use pocketmine\plugin\CommandSender

P.S. onEnable function and onDisable function isn't needed in your case, since all you do is just the messages

 

Another note, it's not pocketmine\plugin\CommandSender
it's pocketmine\command\CommandSender;

 

You also forgot semicolons almost everywhere. Good luck finding them.

 

um thanks! I got it to register as a plugin, but now it gives me the 119 seconds throttle message and I have to take it out of the plugins folder and restart to fix it..
