Working with CLI and missing my namespace classes inside

Question

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.

CLI_Controller.php

<?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());
        });
    }
}

Product_Controller.php

<?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?

Answer 1

I found the issue, and I discover I missing a "vendor" folder in my root of the plugin and inside composer.json i missing a auto-loader of classes.

So what there fix my issue is update my composer.json file and then run a composer install command after inside my plugin folder.

{
    ...
    "require": {
        "php": ">=7.4",
        "guzzlehttp/guzzle": "^7.0"
    },
    "autoload": {
        "psr-4": {
            "WMS\\": "src"
        }
    }
}

So my CLI code work as default, its was a configuration error from my side.
