Jenkins Pipelines defining steps and importing pipeline library library

[Nicolae Vlădescu]

Hello.

I have the following issue with Jenkins 2.0

My Jenkinsfile from repo X contains:

@Library('acme-pipelines@dev')

import acme.jenkins.*

node {

runGradle {

version = '3.3'

cmd = '--version'

}

}

In repo Y (the pipeline library repo) i have `vars/runGradle.groovy` containing:

import acme.jenkins.*

def call(body) {

    def config = [:]

    def utils = new Utils()

    body.resolveStrategy = Closure.DELEGATE_FIRST

    body.delegate = config

    body()

    sh "${utils.getGradleBinPath(config.version)} ${config.cmd}"

}

Also in repo Y i have `src/acme/jenkins/Utils.groovy` containing:

package acme.jenkins

static String getGradleBinPath(String version = null) {

if (!version) {

throw new IllegalArgumentException('A Gradle version must be provided')

}

tool(version).concat('/bin/gradle')

}

When i run the pipeline i get this error:

Running on master in /var/lib/jenkins/workspace/Jenkins Library Development
[Pipeline] {
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline

This is the same error if i wrap the `getGradleBinPath` method in a class named `Utils`, with or without the `static` keyword prefix for the method, i also tried to implement Serializable when using the class version, but same error.

If i remove the `static` keyword in the scripted version it works fine, all of the example code scenarios and above mentioned yield the same error.

I'm pretty new to Groovy so please forgive me if this is not related to Jenkins, or very trivial.

Thank you.

In case of Shared Library classes definition, steps are not directly callable (it's not the case for steps declared inside vars directory).

Can you can try something like :

src/acme/jenkins/Utils.groovy

package acme.jenkins

class Utils {

  static def getGradleBinPath(script, version) {

    if (!version) {

        throw new IllegalArgumentException('A Gradle version must be provided')

    }

    script.tool(version).concat('/bin/gradle')

  }

}

vars/runGradle.groovy

import acme.jenkins.*

def call(body) {

    def config = [:]

    body.resolveStrategy = Closure.DELEGATE_FIRST

    body.delegate = config

    body()

    sh "${Utils.getGradleBinPath(this, config.version)} ${config.cmd}"

}

See https://jenkins.io/doc/book/pipeline/shared-libraries/#accessing-steps => there is a similar example using Maven.

Moreover, you should also be interested by https://issues.jenkins-ci.org/browse/JENKINS-44834 and https://issues.jenkins-ci.org/browse/JENKINS-27393 :-)

Hopefully it helps.

Cheers
