How to reload exact class after renaming the file in Laravel

I have two traits file with the same class:

app/Traits/OperationTools_OLD.php
app/Traits/OperationTools.php

The two files contain the same class name like the following:

<?php
namespace App\Traits;

use Carbon\Carbon;
use App\Http\Helpers\FoxUtils;
use App\Operation;


trait OperationTools {
    use \App\Traits\CavityTools;
   
    public function getProduction(...

The app does not recognize the code of the new file OperationTools.php and it looks to execute the code of the old one.

I have tried to change the trait name of the old file to be trait OperationTools_OLD, but now I get the error when I try to use it:

Trait ‘App\Traits\OperationTools’ not found

I think that there is what is like, a class file map, in the app that should be refreshed but I don’t know how?

I have tried artisan config:clear, view:clear but the issue is the same.

I’m using laravel-5.4 and php-7.4 on Ubuntu and Apache.

>Solution :

Run composer dump-autoload to create a new autoload file
