Hi,

I’m facing an issue with preconfigured jobs. I have written in yaml PipelineJob with parameters, but when I’m trying to use/pass them into job, in Jenkins they are missing. I don’t really know what’s the issue and which part of configuration is failing. Probably Job DSL plugin which I also use is worth to mention here.

Here’s a part of my yaml configuration:

    pipelineJob('Ansible-connection-test') {
      parameters {
        stringParam('HOST', 'defaultHost', 'Enter host from Ansible inventory where job should be executed')
      }
      definition {
        cps {
          script("""\
            pipeline {
              agent any
              stages {
                stage ('Checkout') {
                  steps {
                    git url: '[e-mail]:myRepo.git', branch: 'master'
                  }
                }
                stage ('Deploy') {
                  steps {
                    standardAnsibleDeploy([ansiblePlaybook:'tasks/common/listfiles/main.yml', ansibleExtras: '-e host=${HOST}'])
                  }
                }
              }
            }""".stripIndent())
        }
      }
    }

And here’s the result what’s being visible in Jenkins:

  agent any
  stages {
    stage ('Checkout') {
      steps {
        git url: '[e-mail]:szymonpronos/devops.git', branch: 'master'
      }
    }
    stage ('Deploy') {
      steps {
        standardAnsibleDeploy([ansiblePlaybook:'tasks/common/listfiles/main.yml', ansibleExtras: '-e host='])
      }
    }
  }
}

Did I made something wrong? Any workaround for that? Currently I have to manually correct all pipeline jobs. Thanks

Oh, you’re talking about ${HOST}

Your issue could have been more clear. Please read the section Handling Secrets it specifically says you have to escape ${variables}

You should escape like this: ^${HOST}

JCasC is just trying to be helpful 😆

even the ticket is closed, i leave one comment for escaping since someone will googled here like me.

I use helm chart to deploy the jenkins, so it has another layer to escape for this code. which I end with (\^${computer.jnlpmac})
