Pipeline Groovy error with custom step and libary - jenkins

I have the following issue with my Jenkins 2.0 pipeline library and custom step
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('No Gradle version supplied')
}
tool(version).concat('/bin/gradle')
}
When i run the pipeline i get the following 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 i get the 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.

You cannot access pipeline standard steps directly in classes\scripts under src directory. You should pass the steps to constructor/setter or as method parameter.
Something like that should work
src/acme/jenkins/Utils.groovy
package acme.jenkins
class Utils implements Serializable {
def steps
Utils(steps) {
this.steps = steps
}
String getGradleBinPath(String version = null) {
if (!version) {
throw new IllegalArgumentException('No Gradle version supplied')
}
steps.tool(version).concat('/bin/gradle')
}
}
and then in vars/runGradle.groovy
//..
def utils = new Utils(steps)
//...
See Accessing steps.
Note that steps is a standard global variable that hold pipeline steps.

no such dsl method 'stages' when invoking 'template' script

Upfront, yes I have searched a lot and seen a lot, including on StackOverflow, but nothing has helped so far. I was attempting to define a declarative pipeline in a shared library, but cannot get past the basic definition.
So I wrote the simple vars/pipi.groovy inside my (existing) shared library
def call(config) {
pipeline {
stages {
stage('Prepare') {
steps { echo "preparing ${config.item}" }
}
stage('Build') {
steps { echo "building ${config.item}" }
}
}
}
}
I then created a new pipeline job, containing just the following script
#Library('my-jenkins-library#embeddedpipeline') _
pipi [:]
I understand that this might be because of some scripted vs declarative pipeline, but I cannot see why it should not work. I have no node declaration or anything, and the pipeline configuration seems to be valid enough. I encountered the error first, because I had other elements in there, and for some reason it accepts having a parameters block, but not say an agent, but keeping the example short still does not work for me.
BTW, the library is references from the enclosing folder,
Any suggestions are appreciated
Edit 1: The stack trace (filtered a bit)

this works for me:
In the jenkinsfile:
#Library('jenkinssharedlibrary#feature/your-branch-name') _
templateFromJenkinsLibrary([
parameter1:"${params.parameterDefinedInJenkinsJob}",
parameter2:'arbitraryValue',
agent: 'testagentlabel'
]
then in the jenkins library vars/templateFromJenkinsLibrary.groovy:
import com.ownlibraryDefinedInSrc.someFunction
def call(Map<String, String> passedConfigurationMap) {
pipeline {
agent {
label passedConfigurationMap.agent
}
environment {
PROJECT_VERSION = "${passedConfigurationMap.projectVersion}"
}
tools {
//use this to control the build configurations like maven and jdk used under SCV
jdk passedConfigurationMap.javaVersionToUse
}
stages {
stage('Validate Parameters') {
steps {
script {
echo "Validate"
}
}
}
}
ps: no IDE at hand so I hope I have syntax errors.

Jenkins groovy (SharedLibrary) class can't access WorkflowScript members

I have a simple pipeline script that access a groovy class (which resides in a shared library),
the pipeline script pass a reference (to itself) to the class,
the class then calls a function or a closure found in the script,
that function access a member in that same script,
the result is a groovy.lang.MissingPropertyException exception.
so here is the actual (runnable) code:
Jenkins pipeline script:
#Library("testLib") _
import my.domain.Tester;
public Tester tester = new Tester(this);
def closure()
{
echo "tester: " + tester;
}
node("master")
{
tester.test();
}
com.domain.Tester.groovy class:
package my.domain
class Tester
{
Script scriptRef = null;
public Tester(Script scriptRef)
{
this.scriptRef = scriptRef;
}
public void test()
{
this.scriptRef.closure();
}
}
the exception received:

so obviously it is something happening due to the cps transform procedure the pipeline script goes through, and the script member is not there anymore (not by name and not at scope [probably]),
does anyone have a solution / idea / direction ?
does anyone have info on the CPS Transform process (specifically to Jenkins, not the CPS theory), or how can i see the end product WorkflowScript after the transformation ?
based on daggett solution in the remarks:
jenkins pipeline scripted job is written in groovy
it is then compiled and CPS transformed (during runrime) into a WorkflowScript groovy class with a single method that is executed
and since it is just a groovy class then the groovy scoping rules should apply,
in groovy if you declare a var / 'def' you can do it without the 'def' prefix and that would declare it globally available everywhere in the script,
so change the declaration in the pipeline script to this:
tester = new Tester(this)
and that's it!
Jenkins pipeline script:
#Library("testLib") _
import my.domain.Tester;
// note the definition without the 'def' or Tester or public
tester = new Tester(this);
def closure()
{
echo "tester: " + tester;
}
node("master")
{
tester.test();
}
OR:
since Groovy version 1.8 and up, we can add the #Field annotation and keep the declaration as it is,
how-do-i-create-and-access-the-global-variables-in-groovy
so we can also change the pipeline to look like this:
Jenkins pipeline script:
#Library("testLib") _
import my.domain.Tester;
// note the definition without the 'def' or Tester or public
#Field Tester tester = new Tester(this);
def closure()
{
echo "tester: " + tester;
}
node("master")
{
tester.test();
}

Can anyone please suggest the solution of this error.
You are missing File Loader Plugin
The plugin adds a global fileLoader DSL variable, which provides methods for loading Pipeline objects from remote sources.

Not able to execute a Jenkins pipeline because of syntax issue

1) There are two types of pipeline in jenkins.
Declarative and Scripted.
You mixed two types of syntax and keyword's from both.
node is a keyword for scripted pipeline.
But in beggining of script you declared Pipeline script. So to fix this error, you need remove node.
https://jenkins.io/doc/book/pipeline/
2) For using condition statement you need wrap it with in a script
https://jenkins.io/doc/book/pipeline/syntax/#declarative-steps
3) You need to approve or whitelist your script.
Go to Manage Jenkins -> In-process Script Approval. And press approve.
https://jenkins.io/doc/book/managing/script-approval/
the final result

agent any

Jenkins : how to run groovy script in pipeline

I try to migrate my classic jenkins jobs to pipeline. Actually I have groovy script which read input json. I would like to know how to run groovy script in stage ? I try this but not working :
pipeline {
agent any
stages {
stage('SetEnv') {
steps {
environment {
JSON_BASE_PATH="/json_repo/test"
}
echo 'SetEnv..'
script {
// Get latest JSON FILE FROM /tmp/*.json
def file = new File(JSON_BASE_PATH).listFiles()?.sort { it.lastModified() }?.find{it=~/.json$/}
println ("\nJson file is " + file )
}
}
}
}
You will need to call groovy from a windows batch or shell block with the script file as argument.
You may create a temporary script using the writeFile pipeline method.
Do you mean , run external groovy file in jenkins pipeline or execute groovy sentences in jenkins pipeline?
Both could be fine. Actually I am getting this error message even if "new java.io.File java.lang.String
" signature has been approved :
Scripts not permitted to use method java.io.File listFiles. Administrators can decide whether to approve or reject this signature.
