Jenkins wire: checking explicitly git commit

Question

I want to say something like:

git branch: commitHash, credentialsId: credentialsId, url: url 

Usecase: I do parallel assembly and testing on different platforms and I want each of them to get the same code. This is C ++, and we build on separate platforms, and also build on them.

If I do this above, it fails - the base code assumes that the given branch is actually a branch, or you get something like:

 [Linux64 Build] > git rev-parse origin/e4b6c976a0a986c348a211579f1e8fd32cf29567^{commit} # timeout=10 [Pipeline] [Linux64 Build] } [Pipeline] [Linux64 Build] // dir [Pipeline] [Linux64 Build] } [Pipeline] [Linux64 Build] // node [Pipeline] [Linux64 Build] } [Linux64 Build] Failed in branch Linux64 Build 

I saw the variations on this question asked earlier, although there are no real answers - just suggestions, for example, to hide the source code, etc. Not quite what I need.

The documentation suggests that it should be possible to give explicit hash hashes, perhaps using branches instead, but I cannot parse the syntax and cannot find any examples. When I do this, I get a master branch, I think - in our setup the master does not work.

So far, the only solution I have found was to check the branch and then explicitly call git to get the commit:

  git branch: branch, credentialsId: credentialsId, url: url sh 'git checkout ' + commitHash 

(where the branch is the branch, I initially got the hash at the top of the job. It works, but is not the easiest.

Has anyone got a better way?

Answer 1

Use a common scm step

 checkout([$class: 'GitSCM', branches: [[name: commitHash ]], userRemoteConfigs: [[url: 'http://git-server/user/repository.git']]]) 

Answer 2

Example Yuri G did not work for me when jenkins did not have a job due to the initial check. In this case, the following works. I don’t understand why they are all different.

  def commitId = "<insert sha here>" checkout ( [$class: 'GitSCM', branches: [[name: commitId ]], userRemoteConfigs: [[ credentialsId: 'deploy key for your repo', url: 'repo url']]])
