docker	docker run --rm -v `pwd`:/project cacahouete/phpaudit:latest php -d memory_limit=50000M /usr/local/src/vendor/bin/phpstan.phar analyse src -l 1

I don't know why, but when I use phpstan-symfony with following config:

    symfony:
        container_xml_path: /project/var/cache/dev/srcDevDebugProjectContainer.xml
        console_application_loader: /project/tests/phpstan/console-application.php

I have the following error:

  Line   Xxxx/PaymentBundle/Command/SendTaxReceiptCommand.php

         Run PHPStan with --debug option and post the stack trace to:

(With option --debug)

In class ChildDefinition I found class alias 👍

class_alias(ChildDefinition::class, DefinitionDecorator::class);

I don't understand why phpstan can't found this class :s
