I am trying the below line in my Jenkins Pipeline. In the below set of lines, I am assigning the variable IMAGE_NAME in a shell, and trying to access that in the Jenkins Pipeline script, but not able to do that. Any idea on how to do that?
stage('Build: Get Image') {
steps {
echo 'Getting docker image'
sh "IMAGE_NAME=`grep -ri \"Successfully built\"
$BUILD_FILE_NAME | awk \'{print \$3}\'`"
echo "Image Name is:$IMAGE_NAME"
}
}
You can define it as env variable:
env.some_var = 'AAAA'
And print with:
sh 'echo ${env.some_var}'
proxy_host = 'abc.com'
stage('Docker Up') {
steps{
script{
sh("""
echo ${http_proxy}
""")
}
}
Catch here is to use double quotes " to execute the shell script. I tested it and it works fine.

I have something like this on a Jenkinsfile (Groovy) and I want to record the stdout and the exit code in a variable in order to use the information later.
sh "ls -l"
How can I do this, especially as it seems that you cannot really run any kind of groovy code inside the Jenkinsfile?
The latest version of the pipeline sh step allows you to do the following;
// Git committer email
GIT_COMMIT_EMAIL = sh (
script: 'git --no-pager show -s --format=\'%ae\'',
returnStdout: true
).trim()
echo "Git committer email: ${GIT_COMMIT_EMAIL}"
Another feature is the returnStatus option.
// Test commit message for flags
BUILD_FULL = sh (
script: "git log -1 --pretty=%B | grep '\\[jenkins-full]'",
returnStatus: true
) == 0
echo "Build full flag: ${BUILD_FULL}"
These options where added based on this issue.
See official documentation for the sh command.
For declarative pipelines (see comments), you need to wrap code into script step:
script {
GIT_COMMIT_EMAIL = sh (
script: 'git --no-pager show -s --format=\'%ae\'',
returnStdout: true
).trim()
echo "Git committer email: ${GIT_COMMIT_EMAIL}"
}
Current Pipeline version natively supports returnStdout and returnStatus, which make it possible to get output or status from sh/bat steps.
An example:
def ret = sh(script: 'uname', returnStdout: true)
println ret
An official documentation.
quick answer is this:
sh "ls -l > commandResult"
result = readFile('commandResult').trim()
I think there exist a feature request to be able to get the result of sh step, but as far as I know, currently there is no other option.
EDIT: JENKINS-26133
EDIT2: Not quite sure since what version, but sh/bat steps now can return the std output, simply:
def output = sh returnStdout: true, script: 'ls -l'
If you want to get the stdout AND know whether the command succeeded or not, just use returnStdout and wrap it in an exception handler:
scripted pipeline
try {
// Fails with non-zero exit if dir1 does not exist
def dir1 = sh(script:'ls -la dir1', returnStdout:true).trim()
} catch (Exception ex) {
println("Unable to read dir1: ${ex}")
}
output:
[Pipeline] sh
[Test-Pipeline] Running shell script
+ ls -la dir1
ls: cannot access dir1: No such file or directory
[Pipeline] echo
unable to read dir1: hudson.AbortException: script returned exit code 2
Unfortunately hudson.AbortException is missing any useful method to obtain that exit status, so if the actual value is required you'd need to parse it out of the message (ugh!)
Contrary to the Javadoc https://javadoc.jenkins-ci.org/hudson/AbortException.html the build is not failed when this exception is caught. It fails when it's not caught!
Update:
If you also want the STDERR output from the shell command, Jenkins unfortunately fails to properly support that common use-case. A 2017 ticket JENKINS-44930 is stuck in a state of opinionated ping-pong whilst making no progress towards a solution - please consider adding your upvote to it.
As to a solution now, there could be a couple of possible approaches:
a) Redirect STDERR to STDOUT 2>&1
- but it's then up to you to parse that out of the main output though, and you won't get the output if the command failed - because you're in the exception handler.
b) redirect STDERR to a temporary file (the name of which you prepare earlier) 2>filename (but remember to clean up the file afterwards) - ie. main code becomes:
def stderrfile = 'stderr.out'
try {
def dir1 = sh(script:"ls -la dir1 2>${stderrfile}", returnStdout:true).trim()
} catch (Exception ex) {
def errmsg = readFile(stderrfile)
println("Unable to read dir1: ${ex} - ${errmsg}")
}
c) Go the other way, set returnStatus=true instead, dispense with the exception handler and always capture output to a file, ie:
def outfile = 'stdout.out'
def status = sh(script:"ls -la dir1 >${outfile} 2>&1", returnStatus:true)
def output = readFile(outfile).trim()
if (status == 0) {
// output is directory listing from stdout
} else {
// output is error message from stderr
}
Caveat: the above code is Unix/Linux-specific - Windows requires completely different shell commands.
this is a sample case, which will make sense I believe!
node('master'){
stage('stage1'){
def commit = sh (returnStdout: true, script: '''echo hi
echo bye | grep -o "e"
date
echo lol''').split()
echo "${commit[-1]} "
}
}
For those who need to use the output in subsequent shell commands, rather than groovy, something like this example could be done:
stage('Show Files') {
environment {
MY_FILES = sh(script: 'cd mydir && ls -l', returnStdout: true)
}
steps {
sh '''
echo "$MY_FILES"
'''
}
}
I found the examples on code maven to be quite useful.
All the above method will work. but to use the var as env variable inside your code you need to export the var first.
script{
sh " 'shell command here' > command"
command_var = readFile('command').trim()
sh "export command_var=$command_var"
}
replace the shell command with the command of your choice. Now if you are using python code you can just specify os.getenv("command_var") that will return the output of the shell command executed previously.
How to read the shell variable in groovy / how to assign shell return value to groovy variable.
Requirement : Open a text file read the lines using shell and store the value in groovy and get the parameter for each line .
Here , is delimiter
Ex: releaseModule.txt
./APP_TSBASE/app/team/i-home/deployments/ip-cc.war/cs_workflowReport.jar,configurable-wf-report,94,23crb1,artifact
./APP_TSBASE/app/team/i-home/deployments/ip.war/cs_workflowReport.jar,configurable-temppweb-report,394,rvu3crb1,artifact
========================
Here want to get module name 2nd Parameter (configurable-wf-report) , build no 3rd Parameter (94), commit id 4th (23crb1)
def module = sh(script: """awk -F',' '{ print \$2 "," \$3 "," \$4 }' releaseModules.txt | sort -u """, returnStdout: true).trim()
echo module
List lines = module.split( '\n' ).findAll { !it.startsWith( ',' ) }
def buildid
def Modname
lines.each {
List det1 = it.split(',')
buildid=det1[1].trim()
Modname = det1[0].trim()
tag= det1[2].trim()
echo Modname
echo buildid
echo tag
}
If you don't have a single sh command but a block of sh commands, returnstdout wont work then.
I had a similar issue where I applied something which is not a clean way of doing this but eventually it worked and served the purpose.
Solution -
In the shell block , echo the value and add it into some file.
Outside the shell block and inside the script block , read this file ,trim it and assign it to any local/params/environment variable.
example -
steps {
script {
sh '''
echo $PATH>path.txt
// I am using '>' because I want to create a new file every time to get the newest value of PATH
'''
path = readFile(file: 'path.txt')
path = path.trim() //local groovy variable assignment
//One can assign these values to env and params as below -
env.PATH = path //if you want to assign it to env var
params.PATH = path //if you want to assign it to params var
}
}
Easiest way is use this way
my_var=`echo 2`
echo $my_var
output
: 2
note that is not simple single quote is back quote ( ` ).
I have a shell script inside my jenkins pipeline which will call mvn. For that i have to pass variable value to mvn. The variable is not passing inside the Jenkins pipeline's shell. But when trying from local machine shell it is working fine as expected.
ARTIFACT_NAME="Sample_Artifact"
pipeline{
agent {
node{
label "${AGENT}"
}
}
stages{
stage("Setting MultiJob Properties"){
steps{
sh '''set +x
export VERSION=$(mvn -B -q -Dexec.executable=echo -Dexec.args=\${${ARTIFACT_NAME}} )
echo $VERSION
'''
}
}
}
}
Expected Process: export VERSION=$(mvn -B -q -Dexec.executable=echo -Dexec.args=${Sample_Artifact} )
Expected Output: 1.0001
ARTIFACT_NAME - I am passing it from Jenkins UI.
${${ARTIFACT_NAME}} - This variable is perfectly replace value in Freestyle jobs and it is throwing error in the Pipeline jobs.
Error Message: script.sh: 3: Bad substitution
Can Anyone please help me to resolve the issue?
As Ian wrote, you're passing the whole script as a literal (''') instead of an interpolated string ("""), so the variable name doesn't get substituted with its value:
pipeline{
agent {
node {
label AGENT
}
}
stages {
stage("Setting MultiJob Properties") {
steps {
sh """set +x
export VERSION=\$(mvn -B -q -Dexec.executable=echo -Dexec.args=\${$ARTIFACT_NAME})
echo \$VERSION"""
}
}
}
}
I've created a simple pipeline which is attempting to run a script and then I'll do something else with the output, however the script (CheckTagsDates.sh) never finishes according to Jenkins. If I SSH into the Jenkins slave node, su as the jenkins user, navigate to the correct workspace folder, I can execute the command successfully.
pipeline {
agent {label 'agent'}
stages {
stage('Check for releases in past 24hr') {
steps{
sh 'chmod +x CheckTagsDates.sh'
script {
def CheckTagsDates = sh(script: './CheckTagsDates.sh', returnStdout: true)
echo "${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}")
}
}
}
}
}
}
I have a scenario where i have to read the maven pom versions for different components and assign the version to docker image(TAG). But after i read the pom, assigned it to some global variable it will reset to original value in groovy jenkins script. Below is the sample. HMAP_VERSION value will 1.2.1 but when it is used in the line: sh "docker login -u ${ART_USERNAME} -p ${ART_PASSWORD} test.com" the value will be UNINITIALISED.
Can somebody tell me what might have gone wrong? This will work with single maven file which is read in env block as below:
environment {
CLOADER_VERSION = readMavenPom().getVersion()
}
Below is the sample of what im tring to do.
#! groovy
environment {
HMAP_VERSION = "UNINITIALISED"
CLOADER_VERSION = "UNINITIALISED"
}
stages {
stage('Build Cloader') {
steps {
checkout([$class: 'GitSCM' "rest is removed")
dir('isa-casloader') {
script {
CLOADER_VERSION = readMavenPom().getVersion()
}
container('build') {
sh '/opt/apache-maven/bin/mvn -s settings.xml -B clean install -DskipTests=true'
}
}
}
}
stage ('Build Casloader Docker Image') {
steps {
dir('isa-casloader') {
container('tools') {
echo("CLOADER_VERSION=${CLOADER_VERSION}")
withCredentials() {
sh "docker login -u ${ART_USERNAME} -p ${ART_PASSWORD} testing.com"
sh 'docker build -t testing.com:${CLOADER_VERSION} .'
sh 'docker push testing.com:${CLOADER_VERSION}'
}
}
}
}
}
stage ('Build Heat Map Docker Image') {
steps {
checkout([$class: 'GitSCM', "rest is commented"])
dir('apps') {
container('tools') {
script {
def pom = readMavenPom file: 'pom-docker.xml'
HMAP_VERSION = pom.version
}
echo("HMAP_VERSION=${HMAP_VERSION}")
withCredentials() {
sh "docker login -u ${ART_USERNAME} -p ${ART_PASSWORD} test.com"
sh 'docker build -t test.com:${HMAP_VERSION} .'
sh 'docker push test.com:${HMAP_VERSION}'
}}}}}}}
By my read of your code, you're mixing environment variables with variables within the Groovy context.
These lines create environment variables, which are accessible in the shell as $HMAP_VERSION and $CLOADER_VERSION:
environment {
HMAP_VERSION = "UNINITIALISED"
CLOADER_VERSION = "UNINITIALISED"
}
However, you're populating a Groovy variable here:
script {
CLOADER_VERSION = readMavenPom().getVersion()
}
To instead populate the environment variable, you'd want to use env.CLOADER_VERSION instead.
This changes what context the variables are evaluated in when you're calling out to shell using the sh directive:
1-> sh "docker login -u ${ART_USERNAME} -p ${ART_PASSWORD} testing.com"
2-> sh 'docker build -t testing.com:${CLOADER_VERSION} .'
3-> sh 'docker push testing.com:${CLOADER_VERSION}'
In line number 1 above, the command is quoted using a double quotes (") which means that the variables ART_USERNAME and ART_PASSWORD are evaluating in the context of the Groovy script.
However, in lines 2 and 3 the commands are quoted using a single quote (') which means that those variables are being evaluated by the shell (likely /bin/sh) and therefore using the values from the environment.
The easiest fix would be to ensure that values you want exposed in the shell are always accessed using the env. prefix in the Groovy context:
// set environment for CLOADER_VERSION
env.CLOADER_VERSION = readMavenPom().getVersion()
// print value of environment variable CLOADER_VERSION
echo("CLOADER_VERSION=${env.CLOADER_VERSION}")
// set environment for HMAP_VERSION
env.HMAP_VERSION = pom.version
// print value of environment variable HMAP_VERSION
echo("HMAP_VERSION=${env.HMAP_VERSION}")
Cheers.
Thanks for the response. My issue got resolved. In docker context as shown below,
withCredentials() {
sh "docker login -u ${ART_USERNAME} -p ${ART_PASSWORD} testing.com"
sh 'docker build -t testing.com:${CLOADER_VERSION} .'
sh 'docker push testing.com:${CLOADER_VERSION}'
}
Login command is proper which is inside double quotes, but the next statements were in single quotes. So variables latest value was not getting resolved. When i change the statements to be inside double quotes, it worked!!
Below is the proper command:
withCredentials() {
sh "docker login -u ${ART_USERNAME} -p ${ART_PASSWORD} testing.com"
sh "docker build -t testing.com:${CLOADER_VERSION} ."
sh "docker push testing.com:${CLOADER_VERSION}"
}
Thanks you.
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.
