Gerrit trigger for Jenkins couldn't find any revision to build

I used to have this problem and I think I have now fixed it, I am blaming the Jenkins UI for hiding some essential configuration elements ;)

Here is the output of my Jenkins build prior to the fix:

SOLUTION

You will need to open your build configuration and go to the section 'Source Code Management' as shown below:

Now you will notice that there is a button 'Advanced', click it to reveal the extra fields as below:

Now you can type your refspec here: $GERRIT_REFSPEC

Now either retrigger a failed build or abandon reviews and submit a new one and it should be working.

Here is the output of the Jenkins job now that we have the appropriate refspec:

1. Leave the 'Branches to build > Branch specifier' field blank
2. Click the Advanced button, and set a custom refspec:+refs/heads/feature/my-feature:refs/remotes/origin/feature/my-featureWith these settings, the plugin will correctly perform a fetch and then check out only the 'feature/my-feature' branch.

You could try to configure like that

• Refspec = refs/changes/:refs/changes/
• Branches to build = $GERRIT_REFSPEC

Follow the full configuration there

If you click "Build Now", Jenkins won't be able to get sources since $GERRIT_REFSPEC doesn't exist on that case.
