从自定义捆绑包加载夹具

问：

我正在为 Symfony 构建一个简单的捆绑包，我想知道我是否可以运行位于其中的固定装置，因为它不在项目根文件夹中。 这是我的项目结构：src

Project
|
+--AdminBundle <- My custom bundle
|  +--Controller
|  +--DataFixtures
|  |  |
|  |  +--AdminFixtures.php <- The fixtures I want to run
|  | 
|  +--DependencyInjection
|  +--Entity
|  +--Resources
|
+--assets
+--bin
+--config
+--public
+--src
+--templates
+--vendor

这是 AdminFixtures 的代码.php

namespace ExampleVendor\AdminBundle\DataFixtures;

use App\AdminBundle\Entity\User;
use App\AdminBundle\Entity\Profile;
use Doctrine\Bundle\FixturesBundle\Fixture;

use Doctrine\Common\Persistence\ObjectManager;
use Doctrine\Bundle\FixturesBundle\ORMFixtureInterface;
use Doctrine\Bundle\FixturesBundle\FixtureGroupInterface;
use Symfony\Component\Security\Core\Encoder\UserPasswordEncoderInterface;

class AdminFixtures extends Fixture implements FixtureGroupInterface {
    private $passwordEncoder;


    public function __construct(UserPasswordEncoderInterface $passwordEncoder) {
        $this->passwordEncoder = $passwordEncoder;
    }

    public function load(ObjectManager $manager) {
        // Fixtures stuff
    }

    /**
     * This method must return an array of groups
     * on which the implementing class belongs to
     *
     * @return string[]
     */
    public static function getGroups(): array {
        return ['admin'];
    }
}

当我运行时，我收到一个错误，说：php bin/console doctrine:fixtures:load

[错误]找不到任何要加载的夹具服务。

我读到一些东西，每个实现的类都会自动注册为固定装置，但我认为这是行不通的，因为我在这里寻求帮助。FixtureGroupInterface

如何手动将其注册为夹具？如何使命令起作用？？php bin/console doctrine:fixtures:load
