<br>
I am trying to set up a Gating system using Gerrit, Jenkins, and Zuul (2.5.0 installed using PIP on Debian 8). I managed to get zuul-server, zuul-merger and Jenkins up and running. However, I am facing problems when Jenkins executes zuul-cloner as part of a build.<br>
<br>
In short: zuul-cloner attempts to use 'origin/HEAD', which is present in the repository that zuul-merger prepared on its machine (Hostname "zuulserver"), but which does *not* exist in the repository that zuul-cloner created on the build slave. Zuul-cloner crashes and aborts the build with an error. Google does not provide any insight on the error message. What am I missing?<br>
<br>
Long form: When I run a new build job, Jenkins starts zuul-cloner to prepare the workspace. Here is the relevant line from the Job configuration:<br>
<br>
zuul-cloner <a href="http://zuulserver:8822/p" rel="noreferrer" target="_blank">http://zuulserver:8822/p</a> $ZUUL_PROJECT<br>
<br>
From this run, I get the following log:<br>
<br>
INFO:zuul.CloneMapper:Workspac<wbr>e path set to: /var/jenkins_home/workspace/my<wbr>job<br>
INFO:zuul.CloneMapper:Mapping projects to workspace...<br>

IndexError: No item found with id u'origin/HEAD'<br>
Build step 'Execute shell' marked build as failure<br>
<br>
Cloning the repository actually worked, i.e., I can see the repo including the change to be tested in the Jenkins workspace on the build slave. I can then run "git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/master" in the repository created by zuul-cloner. When I then trigger my change in Gerrit again, the next build run will commence past the call to zuul-cloner. However, manually fixing *every* repository for *every* build job on *every* build slave does not appear to be a viable option. Am I missing something? Is this possibly a bug in Zuul? Googling the error message turns up a couple of commits, but nothing that provides any actual insight.<br>
<br>
I apologize if I picked the wrong mailing list for this kind of question. In this case, please direct me to a more appropriate plaace.<br>
