ERROR Class "User" doesn't exist; please enter an existing full class name. (Symfony)

Question

I'm a noob and my english is very bad but I will try to explain my problem.

I started a new side-project to train in Symfony. I install multiple composer like : profiler, maker, orm, template...

• The first problem :
  The metadata storage is not up to date, please run the sync-metadata-storage command to fix this issue.
  I solved it with changed the serverVersion into .env.local by : ?serverVersion=10.4.11-MariaDB

• The second problem is when I make a Class User with command lign :
  php bin/console make:entity User
  it's ok but when I want make:auth or make:registrationForm he ask me enter the User class, what I do, and I have always the same error:
  [ERROR] Class "User" doesn't exist; please enter an existing full class name.
  My command lign looks like:

 updated: src/Entity/User.php

 Add another property? Enter the property name (or press <return> to stop adding fields):
 >

  Success!

 Next: When you're ready, create a migration with php bin/console make:migration

frede@DESKTOP-M7PFMDG /c/xampp/htdocs/side_project/01-rpg_builder (registration)
λ php bin/console make:migration

  Success!

 Next: Review the new migration "migrations/Version20200625073423.php"
 Then: Run the migration with php bin/console doctrine:migrations:migrate
 See https://symfony.com/doc/current/bundles/DoctrineMigrationsBundle/index.html
frede@DESKTOP-M7PFMDG /c/xampp/htdocs/side_project/01-rpg_builder (registration)
λ php bin/console doctrine:migrations:migrate

 [ERROR] Class "User" doesn't exist; please enter an existing full class name.

I have never had this kind of problem before. I think it's since update doctrine-migrations-bundle "2.1.2" to "3.0.1"

thank you very much for reading me.

Answer 1

Obviously I wrong create my entity User. I make:entity User instead of make:user
