Jenkins groovy global lib declarative pipeline error - jenkins

My jenkins file has below two line
#Library(['global-jenkins-lib#master']) _
driBuildPipeline {}
It is calling "driBuildPipeline.groovy" under VAR dir of global-jenkins-lib.
my script is a below:
def call(body) {
def pipelineParams = [:]
body.resolveStrategy = Closure.DELEGATE_FIRST
body.delegate = pipelineParams
body()
println("Starting Pipeline....")
pipeline {
agent {
kubernetes {
label 'DRIOrchestrationBuild'
yamlFile 'build-pod.yaml'
}
}
options {
buildDiscarder(logRotator(numToKeepStr: '5', daysToKeepStr: '10'))
timestamps()
}
environment {
gsm = 'Name'
}
stages {
stage('DRI Orchestration Build Preparation') {
steps {
sh """
echo 'Prepering.........' /
ls -l
"""
}
}
stage('DRI Orchestration Build Start') {
steps {
sh "echo DRI Orchestration Build Started...."
}
}
}
}
}
but while I am running my build I am getting below error log.

Is this any kind of bug or I am doing it wrong.

I'm not sure about java.lang.NullPointerException: Cannot invoke method call() on null object but I do know you need to add shared library in Manage jenkins - Configure system - Global Pipeline Libraries

Read workspace file in jenkins script

on an old jenkins (2.187) I have a script that take all file of our git repository.
node {
stage('checkout spring-cloud-config') {
dir('config') {
checkout scm
}
}
stage('csv -> yml') {
def files = new File("${workspace}/config/security").listFiles()
for(int i = 0; i < files.size(); i ++){
...
}
This script work fine but we have to migrate on newest Jenkins version.
But this script don't work on our new jenkins (2.319).

Why doesn't ReentrantLock lock in a Jenkins Pipeline?

I cannot seem to get this concurrence pattern to work in my Jenkins Pipeline script as intended. I have simplified the scenario as much as possible and the result still makes no sense. Here is the entire Jenkinsfile:
import java.util.concurrent.locks.ReentrantLock
// create lock and index vars to make sure concurrent threads write different output files
shellLock = new ReentrantLock()
shellIndex = 0
def doIt() {
shellLock.lock()
def threadShellIndex = ++shellIndex
if (threadShellIndex == 1) {
sh("rm -rf shell")
sh("mkdir shell")
}
shellLock.unlock()
sh "touch shell/${threadShellIndex}"
}
node {
checkout scm
runs = [
"1": { doIt() },
"2": { doIt() },
]
parallel runs
}
This does not, as I expect, remove and replace the "shell" directory before both runs proceed to create a file in it. Instead, the console output is:
[Pipeline] parallel
[Pipeline] { (Branch: 1)
[Pipeline] { (Branch: 2)
[Pipeline] sh
[Pipeline] sh
[1] + rm -rf shell
[Pipeline] sh
[2] + touch shell/2
touch: cannot touch ‘shell/2’: No such file or directory
[Pipeline] }
Failed in branch 2
[1] + mkdir shell
[Pipeline] }
Failed in branch 1
[Pipeline] // parallel
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline

How do I get run 2 to wait until run 1 has recreated the directory?
It seems that the reason ReentrantLock has no effect is that pipeline groovy doesn't actually multithread. It uses a single thread to host multiple "green" threads.
From https://github.com/jenkinsci/workflow-cps-plugin:
All program logic is run inside a “CPS VM thread”, which is just a Java thread pool that can run binary methods and figure out which continuation to do next. The parallel step uses “green threads” (also known as coöperative multitasking): it records logical thread (~ branch) names for various actions, but does not literally run them simultaneously.
Since all calls are in the same thread, ReentrantLock re-enters.
In my case, I was able to get around the need to lock with the use of AtomicInteger and some symlink cleverness around re-creating the directory.
import java.util.concurrent.atomic.AtomicInteger
shellCounter = new AtomicInteger()
#NonCPS
def getNextShellCounter() {
return shellCounter.incrementAndGet()
}
...
def threadShellIndex = getNextShellCounter()
// concurrency-safe creation of output dir and removal of previous
def shellDir = "shell.${currentBuild.number}"
sh """#!/bin/bash +x
mkdir -p ${shellDir}
ln -sfn ${shellDir} shell
rm -rf shell.foo `ls -d shell.* | sed -e '/^${shellDir}\$/d' `
"""
With the way threading works here, a simple ++ might have functioned the same, but better safe than sorry.

Jenkins Build error - groovy.lang.MissingPropertyException: No such property: fileLoader for class: groovy.lang.Binding

Objective:
we have a file in our application folder named as JenkinsFile. From that File, we are trying to call a groovy script file which contains the pipeline script of Jenkins build and deploy. The groovy script file is in seperate GITLAB repository.
Jenkins file code:
#!groovy
#Library("usingALibrary") _
def COMMON_REPO = 'GITLAB_URL'
def REDIRECTED_SCRIPT = 'buildJenkinsPipelineScript.groovy'
def CREDENTIALS_ID = 'credentials'
def jenkinsFile
jenkinsFile = fileLoader.fromGit(REDIRECTED_SCRIPT, COMMON_REPO, 'master', CREDENTIALS_ID, 'maven')
try{
jenkinsFile.start()
}
catch(NullPointerException e)
{
echo "Script threw a NullPointerException but it will be omitted."
}
Problem:
The error that we get while building in jenkins is:
First time build. Skipping changelog.

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.

Create a file with some content using Groovy in Jenkins pipeline

I am trying to create a file called groovy1.txt with the content "Working with files the Groovy way is easy."
Note: I don't want to use the shell to create this file, instead I want to use Groovy to achieve this.
I have following script in my Jenkins pipeline.
node {
def file1 = new File('groovy1.txt')
file1.write 'Working with files the Groovy way is easy.\n'
sh 'ls -l'
// Expecting the file groovy1.txt should present with the content mentioned above
}
But it is throwing FileNotFound (permission denied) error as below
java.io.FileNotFoundException: groovy1.txt (Permission denied)

Jenkins Pipeline provides writeFile step that can be used to write a file inside job's workspace.
Take a look at following example:
node {
writeFile file: 'groovy1.txt', text: 'Working with files the Groovy way is easy.'
sh 'ls -l groovy1.txt'
sh 'cat groovy1.txt'
}
Running this pipeline scripts generates following output:
[Pipeline] node
Running on Jenkins in /var/jenkins_home/workspace/test-pipeline
[Pipeline] {
[Pipeline] writeFile
[Pipeline] sh
[test-pipeline] Running shell script
+ ls -l groovy1.txt
-rw-r--r-- 1 jenkins jenkins 42 Jul 8 16:38 groovy1.txt
[Pipeline] sh
[test-pipeline] Running shell script
+ cat groovy1.txt
Working with files the Groovy way is easy.[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
Finished: SUCCESS
Using Java File
As Jon S mentioned in the comment, Java new File("${env.WORKSPACE}/groovy1.txt") will work only if your node step is executed on master node - if it gets executed on slave node then your pipeline code will fail. You can check following Stack Overflow thread for more information:
In jenkins job, create file using system groovy in current workspace
