Class Enqueue\Symfony\Client\Meta\QueuesCommandFactory does not exist

[jg-development]

Hi,
I am trying to install the magento 2 module.
First problem is the usage of an old simple client 0.8 (want to install symfony 2.X)
This can be fixed by upgrading the composer.json to 0.10.
After installing the magento 2 extension with simple client 0.10.7 and amqp-tools I wanted to setup:upgrade, but an error occurs:
"Class Enqueue\Symfony\Client\Meta\QueuesCommandFactory does not exist"

Does anybody have a solution for this?

enqueue/amqp-ext                               0.10.7                    
enqueue/amqp-tools                             0.10.7                    
enqueue/dsn                                    0.10.4                    
enqueue/enqueue                                0.10.7
