I have an issue where the the prompt is allowing user to pick the params value based on what is loaded into the variables. The user can select the value in the variables , but the value of the params is not returning. The echo is blank and also inside the node it is not returning the params value.

Use ${WORKSPACE} Jenkins environment variable in your getNodeNames() function instead of current directory.
Here is my script to get telnet status
#!/bin/bash
IP=$1;
PORT=$2;
exec 3> /dev/tcp/$IP/$PORT
if [ $? -eq 0 ];then echo "PortOpen";else echo "PortClosed";fi
I am calling the func in my pipeline stage
def telnetTest (namespace, release, port) {
script {
// Getting Service IP
def serviceIP = sh (
returnStdout: true,
script: "kubectl get svc -n ${namespace} | grep ${release} | awk '{print \$4}'"
)
echo "ServiceIP: ${serviceIP}"
// Checking Service IP is Exsisting ?
if (serviceIP.equals('')) {
echo "ERROR: Getting service IP failed"
sh 'exit 1'
}
// Telnet Testing
sh "chmod +x telnetPort.sh"
def telnetTesting = sh (
returnStdout: true,
script: "./telnetPort.sh ${serviceIP} ${port}"
)
echo "${telnetTesting}"
}
}
Pipeline Stage
Pipeline {
environment {
NAMESPACE = default
RELEASE = test
PORT = 9040
}
stages {
stage ('Telnet Test') {
steps {
script {
telnetTest ("${NAMESPACE}", "${RELEASE}", "${PORT}")
}
}
}
}
}
Now its taking only first arg passing to the script
Any one let me know why & where i am going wrong
In your function, you write port, and in the defining line, you wrote PORT.
I've created a simple pipeline which is attempting to run a script and then I'll do something else with the output, however the script (CheckTagsDates.sh) never finishes according to Jenkins. If I SSH into the Jenkins slave node, su as the jenkins user, navigate to the correct workspace folder, I can execute the command successfully.
pipeline {
agent {label 'agent'}
stages {
stage('Check for releases in past 24hr') {
steps{
sh 'chmod +x CheckTagsDates.sh'
script {
def CheckTagsDates = sh(script: './CheckTagsDates.sh', returnStdout: true)
echo "${CheckTagsDates}"
}
}
}
}
}
Here is the contents of the CheckTagsDates.sh file
#!/bin/bash
while read line
do
array[ $i ]="$line"
(( i++ ))
done < <( curl -L -s 'https://registry.hub.docker.com/v2/repositories/library/centos/tags'|jq -r '."results"[] | "\(.name)&\(.last_updated)"')
for i in "${array[#]}"
do
echo $i | cut -d '&' -f 1
echo $i | cut -d '&' -f 2
done
Here is the output from the script in the console

How I told you in a comment, I think that is a wrong use of the echo instruction for string interpolation.
Jenkins Pipeline uses rules identical to Groovy for string interpolation. Groovy’s String interpolation support can be confusing to many newcomers to the language. While Groovy supports declaring a string with either single quotes, or double quotes, for example:
def singlyQuoted = 'Hello'
def doublyQuoted = "World"
Only the latter string will support the dollar-sign ($) based string interpolation, for example:
def username = 'Jenkins'
echo 'Hello Mr. ${username}'
echo "I said, Hello Mr. ${username}"
Would result in:
Hello Mr. ${username}
I said, Hello Mr. Jenkins
Understanding how to use string interpolation is vital for using some of Pipeline’s more advanced features.
Source: https://jenkins.io/doc/book/pipeline/jenkinsfile/#string-interpolation
As a workaround for this case, I would suggest you to do the parsing of the json content in Groovy, instead of shell, and limit the script to only retrieving the json.
pipeline {
agent {label 'agent'}
stages {
stage('Check for releases in past 24hr') {
steps{
script {
def TagsDates = sh(script: "curl -L -s 'https://registry.hub.docker.com/v2/repositories/library/centos/tags'", returnStdout: true).trim()
TagsDates = readJSON(text: TagsDates)
TagsDates.result.each {
echo("${it.name}")
echo("${it.last_updated}")
}
}
}
}
}
}
Im new to Jenkins Pipeline , Groovy syntax etc.
I have a Jenkins job that takes 5 parameters.
I want to schedule a pipeline that checks for listings via WGET ( format is csv - i can switch to JSON output also ) and the csv is one row with 5 parameters listed
a,b,c,d,e
I need to parse that list and pass the parameters to the
JOB "IF" there are rows , if not , skip and complete the pipeline.
I have searched and basically got as far as this for testing...:
pipeline {
environment {
testVar='foo'}
agent any
stages {
stage('Example Build') {
steps {
echo 'Hello World'
script {
sh "RESULT=\$(wget -qO- https://www.url.com/getlist)"
sh "echo \$RESULT"
//variable define based on parse of CSV???
}
}
}
stage('Example Deploy') {
when {
expression { testVar=='foo' }
}
steps {
echo 'Deploying'
build job: 'Testing', parameters:
[
string(name: 's_e', value: 'u'),
string(name: 't_e', value: 't'),
string(name: 's_s', value: 'DS'),
string(name: 't_s', value: 'SH'),
string(name: 'efg', value: 'TEST')
]
}
}
}}
Obviously i have more work to do around parse of RESULT (but I am not sure how I can achieve this in Pipeline).
I then need to check for RESULT empty or not , then pass variables to the Build.
I opted for a different option.
Instead I now have a Jenkins Job where I use the "Trigger/Call Builds on other Projects"
Before thats added as a build step , i have some code to get the WGET CSV information.
RESULT=$(wget -qO- https://url.com/getlist)
if [ -z "$RESULT" ]
then
echo "Nothing to do"
# exit 1
else
echo "$RESULT"
s_env_upper=$(echo $RESULT | awk -F',' '{print $1}')
t_env_upper=$(echo $RESULT | awk -F',' '{print $2}')
s_env=$(echo $s_env_upper| tr [A-Z] [a-z])
t_env=$(echo $t_env_upper| tr [A-Z] [a-z])
echo "s_env=$s_env" > params.cfg
echo "t_env=$t_env" >> params.cfg
fi
Hope this helps someone else... i was breaking my heart trying to get pipeline to do the work and answer was simpler.
A step in my pipeline uploads a .tar to an artifactory server. I am getting a Bad substitution error when passing in env.BUILD_NUMBER, but the same commands works when the number is hard coded. The script is written in groovy through jenkins and is running in the jenkins workspace.
sh 'curl -v --user user:password --data-binary ${buildDir}package${env.BUILD_NUMBER}.tar -X PUT "http://artifactory.mydomain.com/artifactory/release-packages/package${env.BUILD_NUMBER}.tar"'
returns the errors:
[Pipeline] sh
[Package_Deploy_Pipeline] Running shell script
/var/lib/jenkins/workspace/Package_Deploy_Pipeline#tmp/durable-4c8b7958/script.sh: 2:
/var/lib/jenkins/workspace/Package_Deploy_Pipeline#tmp/durable-4c8b7958/script.sh: Bad substitution
[Pipeline] } //node
[Pipeline] Allocate node : End
[Pipeline] End of Pipeline
ERROR: script returned exit code 2
If hard code in a build number and swap out ${env.BUILD_NUMBER} I get no errors and the code runs successfully.
sh 'curl -v --user user:password --data-binary ${buildDir}package113.tar -X PUT "http://artifactory.mydomain.com/artifactory/release-packages/package113.tar"'
I use ${env.BUILD_NUMBER} within other sh commands within the same script and have no issues in any other places.
This turned out to be a syntax issue. Wrapping the command in ''s caused ${env.BUILD_NUMBER to be passed instead of its value. I wrapped the whole command in "s and escaped the nested. Works fine now.
sh "curl -v --user user:password --data-binary ${buildDir}package${env.BUILD_NUMBER}.tar -X PUT \"http://artifactory.mydomain.com/artifactory/release-packages/package${env.BUILD_NUMBER}.tar\""
In order to Pass groovy parameters into bash scripts in Jenkins pipelines (causing sometimes bad substitions) You got 2 options:
The triple double quotes way [ " " " ]
OR
the triple single quotes way [ ' ' ' ]
In triple double quotes you can render the normal parameter from groovy using ${someVariable} ,if it's environment variable ${env.someVariable} , if it's parameters injected into your job ${params.someVariable}
example:
def YOUR_APPLICATION_PATH= "${WORKSPACE}/myApp/"
sh """#!/bin/bash
cd ${YOUR_APPLICATION_PATH}
npm install
"""
In triple single quotes things getting little bit tricky, you can pass the parameter to environment parameter and using it by "\${someVaraiable}" or concating the groovy parameter using ''' + someVaraiable + '''
examples:
def YOUR_APPLICATION_PATH= "${WORKSPACE}/myApp/"
sh '''#!/bin/bash
cd ''' + YOUR_APPLICATION_PATH + '''
npm install
'''
OR
pipeline{
agent { node { label "test" } }
environment {
YOUR_APPLICATION_PATH = "${WORKSPACE}/myapp/"
}
continue...
continue...
continue...
sh '''#!/bin/bash
cd "\${YOUR_APPLICATION_PATH}"
npm install
'''
//OR
sh '''#!/bin/bash
cd "\${env.YOUR_APPLICATION_PATH}"
npm install
'''
Actually, you seem to have misunderstood the env variable. In your sh block, you should access ${BUILD_NUMBER} directly.
Reason/Explanation: env represents the environment inside the script. This environment is used/available directly to anything that is executed, e.g. shell scripts.
Please also pay attention to not write anything to env.*, but use withEnv{} blocks instead.
Usually the most common issue for:
Bad substitution
error is to use sh instead of bash.
Especially when using Jenkins, if you're using Execute shell, make sure your Command starts with shebang, e.g. #!/bin/bash -xe or #!/usr/bin/env bash.
I can definitely tell you, it's all about sh shell and bash shell. I fixed this problem by specifying #!/bin/bash -xe as follows:
node {
stage("Preparing"){
sh'''#!/bin/bash -xe
colls=( col1 col2 col3 )
for eachCol in ${colls[#]}
do
echo $eachCol
done
'''
}
}
I had this same issue when working on a Jenkins Pipeline for Amazon S3 Application upload.
My script was like this:
pipeline {
agent any
parameters {
string(name: 'Bucket', defaultValue: 's3-pipeline-test', description: 'The name of the Amazon S3 Bucket')
string(name: 'Prefix', defaultValue: 'my-website', description: 'Application directory in the Amazon S3 Bucket')
string(name: 'Build', defaultValue: 'public/', description: 'Build directory for the application')
}
stages {
stage('Build') {
steps {
echo 'Running build phase'
sh 'npm install' // Install packages
sh 'npm run build' // Build project
sh 'ls' // List project files
}
}
stage('Deploy') {
steps {
echo 'Running deploy phase'
withCredentials([[$class: 'AmazonWebServicesCredentialsBinding', accessKeyVariable: 'AWS_ACCESS_KEY_ID', credentialsId: 'AWSCredentials', secretKeyVariable: 'AWS_SECRET_ACCESS_KEY']]) {
sh 'aws s3 ls' // List AWS S3 buckets
sh 'aws s3 sync "${params.Build}" s3://"${params.Bucket}/${params.Prefix}" --delete' // Sync project files with AWS S3 Bucket project path
}
}
}
}
post {
success {
echo 'Deployment to Amazon S3 suceeded'
}
failure {
echo 'Deployment to Amazon S3 failed'
}
}
}
Here's how I fixed it:
Seeing that it's an interpolation call of variables, I had to substitute the single quotation marks (' ') in this line of the script:
sh 'aws s3 sync "${params.Build}" s3://"${params.Bucket}/${params.Prefix}" --delete' // Sync project files with AWS S3 Bucket project path
to double quotation marks (" "):
sh "aws s3 sync ${params.Build} s3://${params.Bucket}/${params.Prefix} --delete" // Sync project files with AWS S3 Bucket project path
So my script looked like this afterwards:
pipeline {
agent any
parameters {
string(name: 'Bucket', defaultValue: 's3-pipeline-test', description: 'The name of the Amazon S3 Bucket')
string(name: 'Prefix', defaultValue: 'my-website', description: 'Application directory in the Amazon S3 Bucket')
string(name: 'Build', defaultValue: 'public/', description: 'Build directory for the application')
}
stages {
stage('Build') {
steps {
echo 'Running build phase'
sh 'npm install' // Install packages
sh 'npm run build' // Build project
sh 'ls' // List project files
}
}
stage('Deploy') {
steps {
echo 'Running deploy phase'
withCredentials([[$class: 'AmazonWebServicesCredentialsBinding', accessKeyVariable: 'AWS_ACCESS_KEY_ID', credentialsId: 'AWSCredentials', secretKeyVariable: 'AWS_SECRET_ACCESS_KEY']]) {
sh 'aws s3 ls' // List AWS S3 buckets
sh "aws s3 sync ${params.Build} s3://${params.Bucket}/${params.Prefix} --delete" // Sync project files with AWS S3 Bucket project path
}
}
}
}
post {
success {
echo 'Deployment to Amazon S3 suceeded'
}
failure {
echo 'Deployment to Amazon S3 failed'
}
}
}
That's all
I hope this helps
I was having the issue with showing the {env.MAJOR_VERSION} in an artifactory of jar file . show I approaches by keeping of environment step in Jenkinsfile.
pipeline {
agent any
environment {
MAJOR_VERSION = 1
}
stages {
stage('build') {
steps {
sh 'ant -f build.xml -v'
}
}
}
post {
always{
archiveArtifacts artifacts: 'dist/*.jar', fingerprint: true
}
}
}
I got the issue solved and then it was not showing me bad substitution in my Jenkins build output. so environment step plays a more role in Jenkinsfile.
suggestion from #avivamg didn't worked for me, here is the syntax which works for me:
sh "python3 ${env.WORKSPACE}/package.py --product productname " +
"--build_dir ${release_build_dir} " +
"--signed_product_dir ${signed_product_dir} " +
"--version ${build_version}"
I got similar issue. But my usecase is little different
steps{
sh '''#!/bin/bash -xe
VAR=TRIAL
echo $VAR
if [ -d /var/lib/jenkins/.m2/'\${params.application_name}' ]
then
echo 'working'
echo ${VAR}
else
echo 'not working'
fi
'''
}
}
here I'm trying to declare a variable inside the script and also use a parameter from outside
After trying multiple ways
The following script worked
stage('cleaning com/avizva directory'){
steps{
sh """#!/bin/bash -xe
VAR=TRIAL
echo \$VAR
if [ -d /var/lib/jenkins/.m2/${params.application_name} ]
then
echo 'working'
echo \${VAR}
else
echo 'not working'
fi
"""
}
}
changes made :
Replaced triple single quotes --> triple double quotes
Whenever I want to refer to local variable I used escape character
$VAR --> \$VAR
This caused the error Bad Substitution:
pipeline {
agent any
environment {
DOCKER_IMAGENAME = "mynginx:latest"
DOCKER_FILE_PATH = "./docker"
}
stages {
stage('DockerImage-Build') {
steps {
sh 'docker build -t ${env.DOCKER_IMAGENAME} ${env.DOCKER_FILE_PATH}'
}
}
}
}
This fixed it: replace ' with " on sh command
pipeline {
agent any
environment {
DOCKER_IMAGENAME = "mynginx:latest"
DOCKER_FILE_PATH = "./docker"
}
stages {
stage('DockerImage-Build') {
steps {
sh "docker build -t ${env.DOCKER_IMAGENAME} ${env.DOCKER_FILE_PATH}"
}
}
}
}
The Jenkins Script is failing inside the "sh" command-line E.g:
sh 'npm run build' <-- Fails referring to package.json
Needs to be changed to:
sh 'npm run ng build....'
... ng $PATH is not found by the package.json.
