I have the following error when trying to test the sample proposed in the How to create initial seed job section of the README.

Job-dsl support is optional, if you don't user a docker image with job-dsl plugin installed, or you don't configure configuration-as-code to install it, you won't get support for jobs in jenkins.yaml.

Thank you for your help !
I managed to create a quite complete example of an bitbucket organization folder. Do you think it could be interesting to add it to the demos examples to help people like me who struggled with different part of seed jobs ? (the 'traits' for example are not obvious to understand as some of it are not currently possible in pure DSL)

Here is the example :

jenkins:
  systemMessage: "Jenkins configured automatically by Jenkins Configuration as Code Plugin\n\n"

jobs:
  - >
      organizationFolder('Bitbucket Organization Folder') {
        description("Bitbucket orga folder configured with JCasC")
        displayName('My Project')

        // "Projects"
        organizations {
          bitbucket {
            bitbucketServerUrl("https://$SERVER_URL")
            repoOwner("MP")
            credentialsId("bitbucket-http")

            traits {        
              webhookRegistrationTrait {
                mode('ITEM')
              } 
              submoduleOptionTrait {
                extension {
                  disableSubmodules(false)
                  recursiveSubmodules(true)
                  trackingSubmodules(false)
                  reference(null)
                  timeout(null)
                  parentCredentials(true)
                }
              }
            }
          }

        }

        // "Behaviours"
        // For some 'traits, we need to configure this stuff by hand until JobDSL handles it
        // https://issues.jenkins-ci.org/browse/JENKINS-45504
        configure { node ->
            def traits = node / navigators / 'com.cloudbees.jenkins.plugins.bitbucket.BitbucketSCMNavigator' / traits
            traits << 'com.cloudbees.jenkins.plugins.bitbucket.BranchDiscoveryTrait' {
                strategyId('3')   
            }
            traits << 'com.cloudbees.jenkins.plugins.bitbucket.SSHCheckoutTrait' {
                credentialsId('bitbucket-ssh')   
            }

        }    

        // "Project Recognizers"
        projectFactories {
            workflowMultiBranchProjectFactory {
                scriptPath 'ValidationJenkinsfile'
            }
        }

        // "Orphaned Item Strategy"
        orphanedItemStrategy {
          discardOldItems {
            daysToKeep(-1)
            numToKeep(-1)
          }
        }

        // "Scan Organization Folder Triggers" : 1 day
        // We need to configure this stuff by hand because JobDSL only allow 'periodic(int min)' for now
        configure { node ->
          node / triggers / 'com.cloudbees.hudson.plugins.folder.computed.PeriodicFolderTrigger' {
            spec('H H * * *')
            interval(86400000)
          }
        }
      }

Hope it will help and keep up the good work on JCasC, great project !

@ndeloof do you want me to submit a PR to add this example to the demos folder or do you think it is not useful since you have the project to decouple the "jobs" section from the JOb DSL plugin in the near future ?

yogeek on 12 Jul 2018

You're welcome to propose a PR. Not sure when we will get this moved to job-dsl plugin

ndeloof on 12 Jul 2018

done : #358

yogeek on 12 Jul 2018

I'm facing the same issue although I already installed job-dsl and configuration-as-code plugins.

jobs:
  - >
    folder('sample')

nthienan on 27 Mar 2019

It's in the configuration-as-code-support plugin now AFAIK

timja on 27 Mar 2019

I tried installing configuration-as-code-support but it does not work too.

nthienan on 28 Mar 2019

@nthienan can you create an issue, post your yaml file and list of plugins and the exact exception your getting.

jetersen on 28 Mar 2019

@casz My fault. It works now

nthienan on 28 Mar 2019

Hi @nthienan,

I met a similar problem here https://github.com/jenkinsci/configuration-as-code-plugin/issues/280#issuecomment-508158146 and I'm wondering how did you solve it ?

Cheers,

install job-dsl plugin > 1.74

@arnaud-deprez please remove this comment > https://github.com/jenkinsci/configuration-as-code-plugin/issues/280#issuecomment-508158146 as it is completely unrelated

we have pretty active gitter chat so question are best asked there.

install job-dsl plugin > 1.74
or read release notes: https://github.com/jenkinsci/configuration-as-code-plugin/releases/tag/configuration-as-code-1.18

jetersen on 3 Jul 2019

@arnaud-deprez I assume you're using docker? I also assume you persist your JENKINS_HOME directory.
I'd ask that you empty out your plugins folder to give Jenkins a chance to properly load the plugins downloaded by the installplugins.sh script 😓

jetersen on 3 Jul 2019

Hi @casz,

I removed the link to the comment as you suggested.

I'm using Kubernetes (Openshift actually) and I tried both with persistent volume and ephemeral and I have same behaviour.

Note that I have also update the kubernetes plugin to kubernetes:1.16.1 but I don't know if it's related.

arnaud-deprez on 3 Jul 2019

If you remove the jobs node, and check your installed plugins could you please double check that job-dsl plugin is installed and which version 😅

jetersen on 3 Jul 2019

My bad @casz.

I just realized my deployment was not using the tag I was building :-S.
So of course it didn't have job-dsl:1.72.

It is working like a charm.

Thanks for your time and the hints and sorry for the inconvenience :sweat_smile:
