I have a seed job using the plugin Jenkins Job DSL. I also have a shared library.

I have tried using the @Library annotation to load the script and the library method. It cannot find the annotation and using library yields the following error:

No signature of method: simple_pipeline.library() is applicable for argument types: (java.lang.String) values: [platform-engineering-library@master]

How do I load a Jenkins Shared Library in a Jenkins Job DSL seed?

It's possible to use jobDSL from Pipeline. (Im using multibranch pipeline as it allows to configure pipelineTriggers) You can configure your seed job to be a pipeline like this:

def gitCredentialsId      = 'github-jenkins'
def jobsRepoName          = 'https://github.com/my-jobs-repo.git'
def sharedLibraryRepoName = 'https://github.com/shared-library-repo.git'

properties([    
   pipelineTriggers([githubPush()])
])

pipeline {
    agent any
    stages{
        stage('Seed Job') {
            agent any
            steps {

                checkout([
                    $class: 'GitSCM', 
                    branches: [[name: '*/main']], 
                    doGenerateSubmoduleConfigurations: false,
                    extensions: [[$class: 'RelativeTargetDirectory', relativeTargetDir: 'shared-library']], 
                    submoduleCfg: [],
                    userRemoteConfigs: [[credentialsId:  gitCredentialsId, url: sharedLibraryRepoName ]]
                    ])

                git url: jobsRepoName, changelog: false, credentialsId: gitCredentialsId, poll: false, branch: 'main'
                jobDsl targets: 'jobs/**/*_job.groovy', additionalClasspath: 'shared-library/src'
            }
        }
    }
}

This way we can configure our seed job to checkout shared libraries repo into workspace subdirectory shared-library and specify additionalClasspath for jobDSL groovy scripts

So in your groovy scripts you can simply use import without @Library annotation

  • Great solution! Do you know if you get a trust warning for loading shared library code this way? May 1 at 15:52

Setup pipeline name and default version (e.g. master) in "Global Pipeline Libraries" settings. Then use them in your Jenkinsfile as following

#!/usr/bin/env groovy
@Library('YourGlobalPipelineName@YourDefaultVersion') _

pipeline {

}

  • I'm not making a Jenkins pipeline. This is a job dsl seed script.

There are two option

  1. Using jenkins global shared lib setting in gui see documation https://www.jenkins.io/doc/book/pipeline/shared-libraries/

  2. Importing shared library inside jenkins file similart like this follow this blog https://tomd.xyz/jenkins-shared-library/

    library identifier: 'mylibraryname@master',
         //'master' refers to a valid git-ref
         //'mylibraryname' can be any name you like
         retriever: modernSCM([
           $class: 'GitSCMSource',
           credentialsId: 'your-credentials-id',
           remote: 'https://git.yourcompany.com/yourrepo/private-library.git'
     ])
    
     pipeline {
         agent any
         stages {
             stage('Demo') {
                 steps {
                     echo 'Hello world'
                     yourCustomStep 'your_arg'
                 }
             }
         }
    

P.S. When using "@Library _" the this means importing all libraries
