Jenkins pipeline: checkout explicit git commit

Question

I want to be able to say something like:

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

The usecase: I\'m doing parallel build

Answer 1

Yuri G's example didn't work for me when jenkins lacked a workspace due to initial checkout. The following works in this case. I don't understand why they are all that different.

    def commitId = ""

    checkout ( [$class: 'GitSCM',
        branches: [[name: commitId ]],
        userRemoteConfigs: [[
            credentialsId: 'deploy key for your repo', 
            url: 'repo url']]])
