[jstrachan]

Exception in thread "main" org.jboss.weld.exceptions.DeploymentException: Exception List with 1 exceptions:

[iocanel]

The message is not about a service that is missing but about not being able to get a client instance.

Let me see how we can improve that.

[jstrachan]

Aha! I noticed in master that Fabric8 Forge no longer gets a KubernetesClient injected via CDI too btw; I had to add a local hack for now

[iocanel]

Falling back to the default client is broken in master. I am going to push a fix as soon as github connectivity issues are over.
