Class "Symfony\Component\Security\Guard\Authenticator\AbstractFormLoginAuthenticator" does not exist

[537mfb]

Testing Symfony 6.0-RC1, I get the following output when I do symfony console make:auth:

 What style of authentication do you want? [Empty authenticator]:
  [0] Empty authenticator
  [1] Login form authenticator
 > 1

 The class name of the authenticator to create (e.g. AppCustomAuthenticator):
 > AppAuthenticator

 Choose a name for the controller class (e.g. SecurityController) [SecurityController]:
 > 

 Do you want to generate a '/logout' URL? (yes/no) [yes]:
 > 

In MakeAuthenticator.php line 411:

  Class "Symfony\Component\Security\Guard\Authenticator\AbstractFormLoginAuthenticator" does not exist  

make:auth [--firewall-name [FIREWALL-NAME]] [--entry-point [ENTRY-POINT]] [--] <authenticator-type> <authenticator-class> <controller-class> <user-class> <username-field> <logout-setup>

exit status 1

I thought the Guard Authenticator had been deprecated an a new authentication mechanism had been implemented in Symfony 5.3

Yup, we're not coding carefully enough here:

maker-bundle/src/Maker/MakeAuthenticator.php

Line 411 in 0f40c82

$reflectionMethod = new \ReflectionMethod(AbstractFormLoginAuthenticator::class, 'onAuthenticationSuccess');

That should be an easy fix - I'm not sure why the tests didn't catch it, but we'll need to check that too :)

EDIT: the tests DID catch this, but not until Symfony 6.0 was released (which shouldn't have happened, but the tests ARE now correctly failing).
