symfony 4 to 5 cache error when/after upgrade

Question

• My problem : Cache Error when upgrading symfony 4.4 to 5.0 (cache clear work on 4.4 )

• php : 7.2.5 when upgrade, 7.1 before upgrade

• Before update symfony 4.4 to 5, i've followed this doc (symfony doc 4.4 to 5): https://symfony.com/doc/4.4/setup/upgrade_major.html

• i've fix all depreciations

• composer require --dev symfony/phpunit-bridge

• ./bin/phpunit and fix as many problem as possible, only one left :

      Stack trace:
      #0 [internal function]: array_merge(phpunit/phpunit: Array)
      #1 phar:///usr/local/bin/composer.phar/src/Composer/DependencyResolver/DefaultPolicy.php(84): call_user_func_array('array_merge', Array)
      #2 phar:///usr/local/bin/composer.phar/src/Composer/Command/ShowCommand.php(537): Composer\DependencyResolver\DefaultPolicy->selectPreferredPackages(Object(Composer\DependencyResolver\Pool), Array, Array)
  
  
  

When i execute "composer update "symfony/*"" everythings work except the last part(cache:clear) :

```Executing script cache:clear [KO]
 [KO]
Script cache:clear returned with error code 1

Script @auto-scripts was called via post-update-cmd

• There is no 1/AdminController in my Application

• AdminController is the first Controller in /Admin/

• If i change ressourse to /HomeController, i got the same error but with 1/HomeController

• Annotation.yaml :

  controllers
    resource: ../../src/Controller/
    type: annotation
  
  kernel:
    resource: ../../src/Kernel.php
    type: annotation

Answer 1

Perhaps you have to remove the composer.lock and symfony.lock and also update symfony/flex to min 1.18 I would prefer 1.19.2 or 2.2.2.
