How to use Jenkins Pipeline Folder-Level Shared Library?

Question

We have few components which is stored in their own git repositories. Specific combination of those components are built and delivered as solutions for different type of deploym

Answer 1

I guess that proper way to do that is to implement a custom SCMRetriever and use library step.

However, you can use the following hack:

Assuming jenkins/vars/log.groovy in your local repo contains:

def info(message) {
    echo "INFO: ${message}"
}

Your Jenkinsfile can load that shared library from the jenkins/ directory using library step:

node('node1') { // load library
    checkout scm
    // create new git repo inside jenkins subdirectory
    sh('cd jenkins && git init && git add --all . && git commit -m init &> /dev/null') 
    def repoPath = sh(returnStdout: true, script: 'pwd').trim() + "/jenkins"
    library identifier: 'local-lib@master', retriever: modernSCM([$class: 'GitSCMSource', remote: repoPath])
}

node('node2') {
    stage('Build') {
        log.info("called shared lib") // use the loaded library
    }
}
