jenkins pipeline get repository url variable under pipeline script from scm

Question

i'm using Jenkins file that located in my git repository. I have configured new job using the pipeline script from scm that point to my jenkinsfile. I'm trying to use in my Jenkins file pipeline script the git module in order to pull my data from my git repo without configure pre static variable and just to use the variable of the repository URL under pipeline script from scm that already was configured in my job . There is a way to get somehow the variable Repository URL from this plugin without using parameters in my Jenkins pipeline script.

I have already tried the environment variable GIT_URL and other stuff that related to git from here but this didn't work.

Answer 1

You can find all information about scm in scm variable (instance of GitSCM if you are using git). You can get repository URL this way

def repositoryUrl = scm.userRemoteConfigs[0].url  

But if you just want to checkout that repository you can simply invoke checkout scm without needing to specify anything else. See checkout step

Answer 2

from this post I found a way that you can use the checkout scm to get the git repo url like this:

checkout scm
def url = sh(returnStdout: true, script: 'git config remote.origin.url').trim()

but checkout scm will pull the code and I want to avoid from that.

So I found another way (not the pretty one):

node('master'){

  try{
        GIT_REPO_URL = null
        command = "grep -oP '(?<=url>)[^<]+' /var/lib/jenkins/jobs/${JOB_NAME}/config.xml"
        GIT_REPO_URL = sh(returnStdout: true, script: command).trim();
        echo "Detected Git Repo URL: ${GIT_REPO_URL}"  
    }
    catch(err){
        throw err
        error "Colud not find any Git repository for the job ${JOB_NAME}"
  }

}

this is did the trick for me.

Answer 3

Probably not directly a solution for your particular case, as you're working with git.

But for those still working with SVN using the SubversionSCM, the repository URL can be obtained using

def repositoryUrl = scm.locations[0].remote

Answer 4

I believe that the best solution is like this answer. An example using declarative pipeline:

pipeline {
  agent any;
  stages  {
    stage('test'){
      steps {
        script {
          def s = checkout scm;
          if      (s.GIT_URL != null) print s.GIT_URL
          else if (s.SVN_URL != null) print s.SVN_URL
          else print s
        }
      }
    }
  }
}

Note - this does a full checkout. If that is not desirable, I would try to handle that in checkout parameters (like here)
