Gerrit trigger for Jenkins couldn't find any r

Question

I have trouble using Jenkins+Gerrit.

Here is what I got so far:

• Gerrit Trigger configuration in Jenkins seems to be ok: When I push a new changeset, Jenkins build is launched.

• I used this: Jenkins: settings for Gerrit Trigger problems to also be able to launch it "manually".

• As for my configuration, I have something like this: https://stackoverflow.com/a/18347982/2248987. Branch Specifier is $GERRIT_BRANCH and Ref Spec is $GERRIT_REFSPEC

• Gerrit and Git are working fines on their own. Access seems OK too.

Here is my issue. When building (gerrit triggered or manually), log output is:

 > git rev-parse --is-inside-work-tree # timeout=10
Fetching changes from the remote Git repository
 > git config remote.origin.url ssh://user@host:29418/testproject # timeout=10

 > git -c core.askpass=true fetch --tags --progress ssh://user@host:29418/testproject refs/heads/master
 > git rev-parse origin/$GERRIT_BRANCH^{commit} # timeout=10
 > git rev-parse $GERRIT_BRANCH^{commit} # timeout=10
ERROR: Couldn't find any revision to build. Verify the repository and branch configuration for this job.
Finished: FAILURE

I am stuck with this message, tried with empty repo, non-empty ones, and also with or without changeset "in review"

Answer 1

After lot's of struggle and keeping eye on log,finally I got the solution.

It's just configuration mistake that we all did. Once checked check box This project is parameterized Below configuration need to be done

Here I named parameter name as branchgit Now in Source Code Management we need to concentrate on Branches to build whose value should be only "$branchgit" as per below image

Answer 2

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.

Answer 3

Replace $GERRIT_BRANCH with $GERRIT_REFSPEC

Answer 4

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:

Answer 5

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-feature With these settings, the plugin will correctly perform a fetch and then check out only the 'feature/my-feature' branch.

Answer 6

The following settings worked for me: Fill Refspec with $GERRIT_REFSPEC in "Advanced" section. "Branch Specifier" can be blank or any valid value
