Generating code coverage report in Clover XML format ... PHP Fatal error: Cannot declare class ..., because the name is already in use in

Question

I want to get coverage.xml for CodeCov. PHP 8.0.2 PHPUnit 9.5.2 Xdebug 3.0.2

My class. It's very simple, just practice for code coverage src/Car.php

<?php
/**
* This class is for car.
*/

class Car
{
 public function GetColor()
 {
   return 'Blue';
 }
}

Test file. tests/CarTest.php

<?php
include_once __DIR__ .'/../src/Car.php';
use PHPUnit\Framework\TestCase;
/**
 * @coversDefaultClass Car
 */
class CarTest extends TestCase
{
  /**
  * @covers Car::GetColor
  */
  public function testCarGoodColor(): void
  {
    $car = new Car();
    $this->assertSame('Blue', $car->GetColor());
  }
}

When I enter

./vendor/bin/phpunit tests/ --coverage-clover ./coverage.xml

I get this message:

PHPUnit 9.5.2 by Sebastian Bergmann and contributors.

OK (1 test, 1 assertion)

Fatal error: Cannot declare class Car, because the name is already in use in /Applications/CI-CD/src/Car.php on line 8

How to resolve this issue with classes?

Big thanks to LazyOne

Problem was with

include_once __DIR__ .'/

../src/Car.php';

I fix it with autoload. Also, I had index.php in src/ and I add it to ignore for code coverage.
