Creating composer package for Codeigniter 4

Question

I am trying to create my first composer package for Codeigniter 4. However, I always get an error Class 'Myapp\Settings\Greet' not found. I'm totally lost.

I created a folder inside the ThirdParty folder named myapp-settings. Inside of that folder is another folder called src and composer.json.

Here's the content of that composer.json

{
    "name": "myapp/settings",
    "description": ".",
    "license": "MIT",
    "minimum-stability": "dev",
    "autoload": {
        "psr-4": {
            "Myapp\\Settings\\": "src"
        }
    },
    "require": {}
}

I created a test file inside the src folder named Greet.php

<?php namespace Myapp\Settings;

class Greet
{
    public function hello()
    {
        return 'Hey, there!';
    }
}

On codeigniter's App\Config\Autoload.php

public $psr4 = [
    'Myapp\Settings' => APPPATH . 'ThirdParty/myapp-settings/src'
];

Then on codeigniter's default controller I called it.

<?php namespace App\Controllers;

use Myapp\Settings\Greet;

class Home extends BaseController
{
    public function index()
    {
        $h = new Greet();
        echo $h->hello();
    }

    //--------------------------------------------------------------------

}

Once I run it I got an error Class 'Myapp\Settings\Greet' not found. APPPATH\Controllers\Home.php at line 9. How can I fix this?

Instead of editing the codeigniter's app/Config/Autoload.php, revert it and add these lines to the project composer.json:

"repositories": [
    {
        "type": "path",
        "url": "app/ThirdParty/myapp-settings"
    }
],
// "require": {

Then run composer require myapp/settings

Since I have also stuck at this problem, a GitHub repository is created just for it. You might check and clone, watch the commits to understand the steps.
