Re: OpenShift Gitlab webhook Jenkins issues.

Hi Ben,

yes you got right understanding of my problem. 

There is no build associated yet, as it doesn't even get to the stage when it would fireup any build for the pipeline. It's literally a scond after sending the build task to Jenkins.... 

OpenShift version is 3.5. Jenkins sync plugin is 0.1.25.

I configured Gitlab webhook for my test pipeline to fire up a build. The problem is as soon as I commit something jenkins complains with an error below:

To make sure i understand your scenario, you've defined a pipeline buildconfig in openshift and enabled a gitlab webhook trigger to trigger the build?  (vs defining a gitlab trigger in jenkins itself).

It works when I take generic webhook URL however it engages a build regardless of which branch I'm commiting the change to - which is no ideal.

Any ideas why commit number in the code above is null ?

can you share the build json associated w/ the build that was kicked off by the webhook trigger?

also what version of the openshift sync plugin are you running and what version is your openshift cluster?
