Jenkins Pipeline based on groovy : unable to push to the git: Permission denied (publickey)

Question

I am trying to push some changes to the git repository using groovy pipeline syntax. But I am unable to push. Can anyone help me here.

Pipeline Syntax:

        sh '''
        #git checkout pkg_version
        touch README
        git add .
        git status
        git commit -m "Updated Package Version"
        git remote -v
        sshagent(credentialsId) {
            git push origin pkg_version
        }
        #git push origin pkg_version
        '''

Jenkins Error:

origin  ssh://jenkins@gerrit:29418/sfdx_nar (fetch)
origin  ssh://jenkins@gerrit:29418/sfdx_nar (push)
+ git push origin pkg_version
Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

Answer 1

Try using SSHAgent like this in your pipeline:

steps{
  sshagent(['your-credential-id']) {
    sh "git-steps..."
  }
}
