How to load a component in console/shell

Question

In CakePHP, how do I load a component in a shell?

I have some xml utilities that I use across some of my controllers. One of the controller launches a heavy task via the cake console, so that it can quietly run in the background via PHP CLI, while the user's request is immediately completed (once the task done, it will e-mail the results to the user).

The xml utilities are generic enough to be used in controller and shell, are too specific to the application to warrant them vendor status. The offered solution with the Lib folder does not work as in CakePhp v3 there seems to be no Lib folder.

After some quite some time spent, I managed to load my controller component to the shell task. Here is how to:

namespace App\Shell;

use Cake\Console\Shell;

use Cake\Core\App;
use Cake\Controller\Component;
use Cake\Controller\ComponentRegistry;
use App\Controller\Component\XmlUtilitiesComponent;   // <- resides in your app's src/Controller/Component folder

class XmlCheckShell extends Shell
{

    public function initialize() {
        $this->Utilities = new XmlUtilitiesComponent(new ComponentRegistry());
    }

...

$this->Utilities can now be used across my entire shell class.
