when trying to install, on php 7.2 / Symfony 3.4, the following set of packages:

ezsystems/ezplatform:~2.3.2 ezsystems/ezplatform-xmltext-fieldtype:^1.7 ezsystems/behatbundle:^6.5 netgen/tagsbundle:^3.2 sensio/generator-bundle

what happens is that ezsystems/repository-forms gets pulled in, without a mandatory dependency on ezsystems/ezplatform-user bundle.

 Symptoms are:

 
RuntimeException: Cannot autowire service "ezrepoforms.controller.user_register": argument "$userRegisterController" of method "EzSystems\RepositoryFormsBundle\Controller\UserRegisterController::__construct()" has type "EzSystems\EzPlatformUserBundle\Controller\UserRegisterController" but this class was not found. Did you forget to define the environment variable KERNEL_DIR?
