Regression for groovy routes

[nicolaferraro]

When I try to run the example I get:

@oscerd , @zregvart do you think we have any chance to run a dev instance of Openshift in Apache CI?

Currently PR builds are disabled because there was a issue with dependencies, but I think it's easy to overcome that problem by checking-in the vendor dir... What about minishift / oc cluster up to avoid breaking things?

[lburgazzoli]

Looks like the algorithm to automatically detect the dependencies does no work for this case so you need to explicit require the camel-groovy dependency within kamel run or we need to add the groovy dependency if the files ends with .groovy or the language is set to groovy.

Will send a pr

@oscerd , @zregvart do you think we have any chance to run a dev instance of Openshift in Apache CI?

Not sure, I've created a build to see if the Docker is installed, from what I know is that some changes need to be made to the Docker and firewall configuration to get the oc cluster up to work, so it might be a stretch.

[zregvart]

We could ask for a VM from INFRA.

[zregvart]

CI nodes have Docker version 17.05.0-ce, build 89658be installed, we can experiment with that to some extent but if I'm not mistaking for oc cluster up the Docker/firewall configuration needs to be modified.
