checkout scm on the agent does not respect git 'Discover other refs' in multibranch pipeline

XMLWordPrintable

      I'm trying to use the git plugin to detect pull requests from my git repository which is located in Azure DevOps

      I'm using the following configuration in Multibranch Pipeline

      it seems that the initial git clone is actually works on the jenkins controller

      also in my local PC I can perform git checkout to this PR

      git checkout pull/74/merge
      # output:
      Branch 'pull/74/merge' set up to track remote branch 'pull/74/merge' from 'origin'.
      Switched to a new branch 'pull/74/merge'

       

      But When the jenkins is trying  to perform checkout scm on a different agent (node)

      stage('Generate') {
          node ('linux') {
              checkout scm
          }
      

      or 

      pipeline {
          agent { 
              label 'linux'
          }
          stages {
              stage('Initialize') { 
                steps {
                  checkout scm

      note: in declarative pipeline the jenkins will try automtically to perform checkout scm on the agent node and it will failed too.

      it's getting the following error:

       > git rev-parse --is-inside-work-tree # timeout=10
      Setting origin to https://dev.azure.com/<account>/<project>/_git/<repo>

      why the step checkout SCM is not respecting the git Discover other refs?

      another way to workaround this?
