Github Pull Request Plugin

Question

I'm trying to setup the pull request plugin. I've configured it as suggested in the documentation but if I specify the branch to build as ${sha1} then that variable doesn't seem to be resolved. So in my logs:

Building in workspace /Users/sat/.jenkins/jobs/JenkinsTest/workspace
> /usr/local/bin/git rev-parse --is-inside-work-tree
Fetching changes from the remote Git repository
> /usr/local/bin/git config remote.origin.url git@githubenterprise.parc.com:stucker/tester.git
Fetching upstream changes from git@githubenterprise.parc.com:stucker/tester.git
> /usr/local/bin/git --version
> /usr/local/bin/git fetch --tags --progress git@githubenterprise.parc.com:stucker/tester.git   +refs/pull/*:refs/remotes/origin/pr/*
> /usr/local/bin/git rev-parse origin/${sha1}^{commit}
> /usr/local/bin/git rev-parse ${sha1}^{commit}

But I don't know why that wouldn't work. This is coming off of a push triggered by the standard web hook

Answer 1

I found that you can't run the regular build hook and the pull request on the same job - I had to have separate jobs - one for doing a regular build, and one for doing a pull request build. With that everything works fine.

Answer 2

If you get

Failed to rev-parse: origin/${sha1}
No candidate revisions

, it could be related to issue 5.

A couple of suggestions:

• 5#issuecomment-14308061:
  I just had the same issue with v1.5 and I got it solved by cloning the job and deleting the old one.

• 5#issuecomment-19826662:
  In my case, "Branches to build" field in jenkins configuration form was like "feature/abc/main". My colleague @defragged has suggested to specify branch name without forward slashes ("/"). So I checked out new branch "abcMain" of "feature/abc/main" and build the job. It worked for me.

  I was having the same problem with a Github Pull Request job, and it turned out I was missing the necessary refspec "+refs/pull/:refs/remotes/origin/pr/" from my job.

• JENKINS-20502 "Cannot find any revision to build on clean workspace" (which doesn't seem to be in included in a Jenkins release yet)

• Other open issues for the GitHub pull request builder plugin (repo janinko/ghprb, forked at jenkinsci/ghprb-plugin), like issue 17097.
