Jenkins to use git locally

Using Jenkins

I try to set up the system property ‘hudson.plugins.git.GitSCM.ALLOW_LOCAL_CHECKOUT’ to true. I am doing it in Script Console, and getting response True. But still can not work with my local git. How to make it really working?

Hello @Jacck and welcome to this community. :wave:

As far as I know, to enable Jenkins to use a local Git repository, you need to set (as you did) the system property hudson.plugins.git.GitSCM.ALLOW_LOCAL_CHECKOUT to true and make sure that Jenkins has the necessary permissions to access the local repository. :mag_right:

Here are some steps that might help you to achieve this:

  1. You can set the system property in the Jenkins Script Console as you did: System.setProperty('hudson.plugins.git.GitSCM.ALLOW_LOCAL_CHECKOUT', 'true')
  2. In your Jenkins job configuration, set the repository URL to the local path of your Git repository. For example, if your repository is located at /path/to/your/repo, set the repository URL to file:///path/to/your/repo.
  3. Make sure that the Jenkins user has read and write permissions to the local Git repository directory.
  4. Sometimes, changes to system properties require a Jenkins restart to take effect. :person_shrugging:
    Restart Jenkins to ensure the property is applied.

Here is an untested example of how to configure the repository URL in a Jenkins pipeline:

pipeline {
    agent any
    stages {
        stage('Checkout') {
            steps {
                git url: 'file:///path/to/your/repo', branch: 'main'
            }
        }
        stage('Build') {
            steps {
                // Your build steps here
            }
        }
    }
}

Setting a system property via script console will not change the value. The reason is that the system property is evaluated once at Jenkins startup. You can set the property as a command line parameter to the JVM of Jenkins (java -Dhudson.plugins.git.GitSCM.ALLOW_LOCAL_CHECKOUT=true -jar jenkins.war ...)
But you can still modify the behaviour of the git plugin by running
hudson.plugins.git.GitSCM.ALLOW_LOCAL_CHECKOUT=true in the script console.
