Main class not found

im having another brain fart with Main class not found

Plugin.yml:

Code:

name: CustomPotions
main: TetroYT\CustomPotions\Main
api: [3.0.0]
version: 1.0
author: TetroYT
permissions:
 cp.cp:
  default: true

Main:

PHP:

<?php

declare(strict_types=1);

namespace Main;

use CustomPotions\commands\CustomPotionsCommand;

The folders:

 

Your namespace should be
TetroYT\CustomPotions and your class should be called Main.
Also your use statement didn't have the full namespace

PHP:

<?php

declare(strict_types=1);

namespace TetroYT\CustomPotions;

use pocketmine\plugin\PluginBase;
use TetroYT\CustomPotions\commands\CustomPotionsCommand;

class Main extends PluginBase {

}
