Composer doesn't autoload custom package - php

Question

acknowledgement:
First of all this is my first post for help, as i went trough a lot of articles on stackoverflow and other resources and just could not find solution.
Problem sounds familiar but i just can't figure it out, maybe because im stuck on it for 2 days now. Another note, this is my first package so yes im not 100% sure what im doing.
Structure:
- laravel-project
- ...
- packages
- my-custom-package
- src
- MyCustomPackageServiceProvider.php
- composer.json
- public
- resources
- routes
- ...
- composer.json
So it is basic Laravel 5.8 + inside added package folder for local package devolment (it has been moved to repo as well)
Current Code (simplified as its actual work project):
File: laravel-project/packages/my-custom-package/composer.json
{
"name": "company/my-custom-package",
"type": "library",
"require": {
"php": ">=7.2",

}
},
"minimum-stability": "dev"
}
File: laravel-project/packages/my-custom-package/src/MyCustomPackageServiceProvider.php
<?php
namespace Company\MyCustomPackage;
use Illuminate\Support\ServiceProvider;
class MyCustomPackageServiceProvider extends ServiceProvider {
public function boot()
{
$this->loadRoutesFrom(__DIR__ . '/routes/web.php');
$this->loadMigrationsFrom(__DIR__ . '/database/migrations');
}
public function register()
{
}
}

Explanation: ~/testlaravel/ is folder path inside Vagrant machine for project originaly url was "packages/my-custom-package" buti changed for this extended version just in pure attempt of making it work.
File: config/app.php (added service provider)
Company\MyCustomPackage\MyCustomPackageServiceProvider::class
Issue:
First i made this thing localy and it worked i was following for quick setup instructions from
"Create Laravel Composer Package from scratch to upload on packagist" Author: Bitfumes, and package worked, I could run composer update, then i added to app.php my package and i could run custom route and it all worked.
After that i moved package to git repo, and required it in same way only changed "repositories" field to
"repositories": [
{
"type": "vcs",
"url": "git#git.fulllink.co:john/my-custom-package.git"
}
]
and when you run composer update, you can see that afterwards inside vendor/ files you have Company folder with package inside it, BUT if you leave config/app.php service provider it starts to complain that there is
*Class 'Company\MyCustomPackage\MyCustomPackageServiceProvider' not fo und*
After some f*** around i found out that yes my autoload_classmap (cant remember original post) did not contain my package , so today i decided to try again local and see the difference, does it been added to map file, and now i get same error when requiring local package and i can't make it work anymore.
I been deleting vendor folder and lock file , composer dump-autoload, but that doesnt help. Im just thinking is thgere anything else supercached?
!!UPDATE!!
Im not even more confused. In composer.json (project one i tested on actual project repo now where is required another 2 local git repos). So i have now 4 packages in vendor/Company/{4 packages} , i compared all 4 package composer.json and i can't find any major difference but all of them have been loaded to autoload mapping except mine. Only major difference i can see, those two packages doesnt use ServiceProvider.php file , but i dont see how that impacts or changes things.
