Target class [DatabaseSeedersRoleTableSeeder] does not exist

So I’ve been creating a CMS with Laravel and when I run this command to migrate the tables

php artisan migrate:fresh --seed

I’ve been experiencing this error

Dropped all tables successfully.
Migration table created successfully.

I’ve tried searching to see if someone has the same problem as me, but there seem to be no similar problems. I also can’t tell if the migrations went through or not.

EDIT: Here is the seeder class

<?php

use AppModelsRole;
use IlluminateDatabaseSeeder;

class RoleTableSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        $role_regular_user = new Role;
        $role_regular_user->name = 'user';
        $role_regular_user->description = 'A regular user';
        $role_regular_user->save();
    
        $role_admin_user = new Role;
        $role_admin_user->name = 'admin';
        $role_admin_user->description = 'An admin user';
        $role_admin_user->save();
    }
}

Here is the project structure

app
-> Console
-> Exceptions
-> Http
-> Models
  -> Role.php
-> Providers
database
-> Factories
-> Migrations
-> Seeders
  RoleTableSeeder.php

Answer

From the docs https://laravel.com/docs/8.x/upgrade#seeder-factory-namespaces

<?php

// 👇 add this line 
namespace DatabaseSeeders;

use AppModelsRole;
use IlluminateDatabaseSeeder;

class RoleTableSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        $role_regular_user = new Role;
        $role_regular_user->name = 'user';
        $role_regular_user->description = 'A regular user';
        $role_regular_user->save();
    
        $role_admin_user = new Role;
        $role_admin_user->name = 'admin';
        $role_admin_user->description = 'An admin user';
        $role_admin_user->save();
    }
}

Also just as a Laravel TIP

Instead of

$role_regular_user = new Role;
$role_regular_user->name = 'user';
$role_regular_user->description = 'A regular user';
$role_regular_user->save();

Consider using

$role_regular_user = Role::create([
    'name' => 'user',
    'description' => 'A regular user',
]);

It’s much cleaner

Don’t forget to add $fillable property in you Role model
