How to clone a directory from a remote repo in a Jenkins pipeline script?

[Mark Allison]

Hi,

I have a large repo in GitHub Enterprise and need to clone a sub-directory from it on my Jenkins build server and just build that sub-directory. I am using a pipeline script and have this right now:

node {

    stage ('checkout') {

        git url: 'g...@github.devops.mycompany.local:Org/MyLargeRepo.git'

    }

}

What I want is to clone from github.devops.mycompany.local:Org/MyLargeRepo/path/to/subproject

I know I probably need to use sparse and/or shallow checkouts, but can't seem to work out how to configure that in a Jenkins pipeline script with the git plugin. Any ideas?

Use the 'checkout' step and specify Git SCM. That should allow you to use all the options available in Git. Use the snippet generator for this.

Daniel, how does that show checking out a directory within a repo? Do you have something more concrete? The snippet generator does not show this. 

[Mark Waite]

Checking out to a subdirectory within a workspace requires that you nest the checkout() step inside a dir("subdir-name") step.  The snippet generator only shows one at a time (as far as I recall), so it won't show you that combination.

Refer to https://github.com/MarkEWaite/jenkins-bugs/blob/JENKINS-43052/Jenkinsfile for an example of that technique.

Hi Mark,

I am trying to checkout FROM a remote subdirectory within a repo not to a subdirectory. Does anyone know how to do that with the git plugin?

[Stephen Connolly]

Git doesn't really do that.

I'd probably see if there is a command from the CLI that does what you want and then just use a `sh` step to do that

(I'm betting there is no such CLI command BTW)

From CLI you can

git checkout <sha or branch> -- path/to/subdir/

just that you would need to be in the repository so maybe clone an empty branch or the first commit of the repo instead of the large repo branch and then checkout the files from CLI

Check out the snippet for git: checkout and try the sparse checkout advanced option

checkout changelog: false, poll: false, scm: [

    $class: 'GitSCM',

    branches: [[name: '*/master']],

    doGenerateSubmoduleConfigurations: false,

    extensions: [

       [

         $class: 'SparseCheckoutPaths',

         sparseCheckoutPaths: [[path: '/my/path']]

       ]

    ],

    submoduleCfg: [],

    userRemoteConfigs: [[url: 'ssh://us...@domain.com:x/11346/myrepo.git']]]
