ENDSSH command not found-CodePudding

I'm writing a jenkins pipeline jenkinsfile and within the script clause I have to ssh to a box and run some commands. I think the problem has to do with the env vars that I'm using within the quotes. I'm getting a ENDSSH command not found error and I'm at a loss. Any help would be much appreciated.

stage("Checkout my-git-repo"){
    steps {
      script {
        sh """
          ssh -o StrictHostKeyChecking=accept-new -o LogLevel=ERROR -o UserKnownHostsFile=/dev/null -i ${JENKINS_KEY} ${JENKINS_KEY_USR}@${env.hostname} << ENDSSH
          echo 'Removing current /opt/my-git-repo directory'
          sudo rm -rf /opt/my-git-repo
          echo 'Cloning new my-git-repo repo into /opt'
          git clone ssh://${JENKINS_USR}@git.gitbox.com:30303/my-git-repo
          sudo mv /home/jenkins/my-git-repo /opt
          ENDSSH
        """
      }
    }
  }

-bash: line 6: ENDSSH: command not found

CodePudding user response：

I'm personally not familiar with jenkins, but I'd guess the issue is the whitespace before ENDSSH

White space in front of the delimiter is not allowed.

Try either removing the indentation:

stage("Checkout my-git-repo"){
    steps {
      script {
        sh """
ssh -o StrictHostKeyChecking=accept-new -o LogLevel=ERROR -o UserKnownHostsFile=/dev/null -i ${JENKINS_KEY} ${JENKINS_KEY_USR}@${env.hostname} << ENDSSH
echo 'Removing current /opt/my-git-repo directory'
sudo rm -rf /opt/my-git-repo
echo 'Cloning new my-git-repo repo into /opt'
git clone ssh://${JENKINS_USR}@git.gitbox.com:30303/my-git-repo
sudo mv /home/jenkins/my-git-repo /opt
ENDSSH
        """
      }
    }
  }

OR ensure that the whitespace is only tabs and replace << with <<-:

Appending a minus sign to the redirection operator <<-, will cause all leading tab characters to be ignored. This allows you to use indentation when writing here-documents in shell scripts. Leading whitespace characters are not allowed, only tab.
