Working with CLI and missing my namespace classes inside

I’m very new to WordPress development. I hit this error when i developering my own class and namespace to do the life easier to reuse my code on cross of platforms/frameworks.

I have added my CLI command like this

wp product:sync 

And when i run my CLI command whitout my class its run as it shut, I can get access to the internel WordPress functions did not working.


<?php  namespace WMS\Controllers;  use WMS\Controllers\CLI\CLI_Products;  class CLI {     function init()     {         add_action('cli_init', function () {             $  product_cli = new CLI_Products();              \WP_CLI::add_command('product:sync', $  product_cli->execute());             \WP_CLI::add_command('stock:sync', $  product_cli->hello_world());             \WP_CLI::add_command('order:sync', $  product_cli->hello_world());         });     } } 


<?php  namespace WMS\Controllers\CLI;  use WMS\Controllers\WMSApi\APIService\Items;  class CLI_Products {     public function hello_world()     {         \WP_CLI::line('Hello World!');     }      function execute()     {         $  api_items = new Items();          $  args = array(             'post_type'      => 'product',             'posts_per_page' => 10         );          $  loop = new \WP_Query($  args);         while ($  loop->have_posts()) {             $  loop->the_post();             global $  product;              if ($  product->get_sku()) {                 $  item = [                     'sku' => $  product->get_sku(),                     'description' => get_the_title()                 ];                  print_r($  item);             } else {                 echo 'Product missing SKU number';             }         }          $  items->import($  item);         wp_reset_query();     } } 

So when I run this command its giving this error

PHP Fatal error: Uncaught Error: Class ‘WMS\Controllers\WMSApi\APIService\Items’ not found in /var/www/frontend/wp-content/plugins/wordpress-woocommerce-plugin/src/Controllers/CLI/Product_Controller.php:16 Stack trace: #0 /var/www/frontend/wp-content/plugins/wordpress-woocommerce-plugin/src/Controllers/CLI_Controller.php(14): WMS\Controllers\CLI\CLI_Products->execute()

So its look like the main file did not load success, is there a way or work a round to load custom class/namespaces inside my CLI commands?
