Unable to locate publishable resources when trying to publish a Laravel Package - php

Question

My Directory set-up looks like this:
|- packages
|-|-- Iezon
|---|-- Core
|-- Admin
|-- src
|--|-- database
|-----|-- migrations
|--------|-- xxxx_xx_xx_xxxxxx_create_admin_panels.php
|--|-- Http
|----|-- routes.php
|--|-- Providers
|-----|-- AdminServiceProvider.php
|--|-- Resources
|-----|-- views
My AdminServiceProvider.php looks like this:
namespace Iezon\Core\Admin\Providers;
use Illuminate\Support\ServiceProvider;
class AdminServiceProvider extends ServiceProvider
{
public function boot()
{
$this->loadRoutesFrom(__DIR__ . '/../Http/routes.php');
$this->loadViewsFrom (__DIR__ . '/../Resources/views', 'admin');
}
public function register()
{
$this->publishes([__DIR__ . '/../database/migrations', database_path('migrations')]);
}
protected function loadRoutesFrom(string $path)
{
require_once $path;
}
}
My composer.json looks like this:
"autoload": {
"psr-4": {
...
"Iezon\\Core\\Admin\\": "packages/Iezon/Core/Admin/src",
...
}
}
When I run composer dumpautoload and then try to run:
php artisan vendor:publish --provider="Iezon\Core\Admin\Providers\AdminServiceProvider"
I get this:
Unable to locate publishable resources.
I then check it exists with php artisan vendor:publish and it does not show in the list of Providers. What am I missing?

$this->publishes(...) actually belongs inside the boot method, not in register. Also, you need to pass an associative array, but instead you pass two individual values. Finally, it is a best practice to only call publishes when the provider is actually running in console like this:
if ($this->app->runningInConsole()) {
$this->publishes([__DIR__ . '/../database/migrations' => database_path('migrations')]);
}
