I have a Spring Cloud Dataflow installed on an Openshift cluster. I try to register an application, then to create a task, and everything is fine, but when I try to schedule the task I got the following exception:

I don't know what does it mean, I'm a newbie in Dataflow. I don't understand why he is trying to use Maven instead of a kubernetes deployer and why I get this error. Could someone provide me some more explanation?
I'm registering the applications as docker containers, by the way.
