Creating controller both for CRUD and API REST

I'm builing 2 controllers
Let's say Project entity

One controller will handle the CRUD, Views, etc.
app\Controllers\Projects.php

PHP Code:

<?php

namespace App\Controllers;

class Projects extends BaseController
{
    public function index()
    {
    }
} 


The other, will handle the API REST Resources
app\Controllers\api\Project.php

PHP Code:

<?php
namespace App\Controllers;

use CodeIgniter\RESTful\ResourceController;

class Project extends ResourceController
{
    protected $modelName = '';
    protected $format    = 'json';
    public function index()
    {
    } 


app\Config\Routes.php

Code:

$routes->get('/projects', 'Projects::index');
$routes->resource('/api/project', ['only' => ['index', 'show']]);

When I call the api route with Browser or Postman, I get

ErrorException #64
Cannot declare class App\Controllers\Project, because the name is already in use in D:\www\test\app\Controllers\api\Project.php on line 0

I don't understand it because classNames differ in both Controllers. Any clues? Maybe routes is bad configured?
Thanks for any suggestion
