I'm trying to fetch the environment parameters/variables from Jenkins using a System Groovy script.
I want to pass these variables to a post-build step, but I'm getting the following error while trying to get these variables to show up in the jenkins console.
Error : groovy.lang.MissingMethodException: No signature of method:org.jenkinsci.plugins.workflow.job.Workflowjob.getProperties() is applicable for argument types: (java.lang.Class) values: [class hudson.model.ParametersDefinitionProperty]
How can I fetch these parameters?
Would appreciate any help I can get. Thanks!
import hudson.model.*
for(item in Hudson.instance.items) {
prop = item.getProperty(ParametersDefinitionProperty.class)
if(prop != null) {
echo "Browser name: ${BROWSER_NAME}"
echo "env name: ${ENV_NAME}"
println("Parameters for "+item.name)
for(param in prop.getParameterDefinitions()) {
try {
echo "param.name+""+param.defaultValue"
}
catch(Exception e) {
println(e.printStackTrace())
}
}
}
}
echo "groovy ends here"

Hi My jenkins file code is as follows : I am basically trying to make call to a python script and execute it, I have defined some variables in my code : And when i am trying to run it, It gives no such property error in the beginning and I cant find out the reason behind it.
I would really appreciate any suggestions on this .
import groovy.json.*
pipeline {
agent {
label 'test'
}
parameters {
choice(choices: '''\
env1
env2'''
, description: 'Environment to deploy', name: 'vpc-stack')
choice(choices: '''\
node1
node2'''
, description: '(choose )', name: 'stack')
}
stages {
stage('Tooling') {
steps {
script {
//set up terraform
def tfHome = tool name: 'Terraform 0.12.24'
env.PATH = "${tfHome}:${env.PATH}"
env.TFHOME = "${tfHome}"
}
}
}
stage('Build all modules') {
steps {
wrap([$class: 'BuildUser']) {
// build all modules
script {
if (params.refresh) {
echo "Jenkins refresh!"
currentBuild.result = 'ABORTED'
error('Jenkinsfile refresh! Aborting any real runs!')
}
sh(script: """pwd""")
def status_code = sh(script: """PYTHONUNBUFFERED=1 python3 scripts/test/test_script.py /$vpc-stack""", returnStatus: true)
if (status_code == 0) {
currentBuild.result = 'SUCCESS'
}
if (status_code == 1) {
currentBuild.result = 'FAILURE'
}
}
}
}
}
}
post {
always {
echo 'cleaning workspace'
step([$class: 'WsCleanup'])
}
}
}
And this code is giving me the following error :
hudson.remoting.ProxyException: groovy.lang.MissingPropertyException: No such property: vpc for class
Any suggestions what can be done to resolve this.
Use another name for the choice variable without the dash sign -, e.g. vpc_stack or vpcstack and replace the variable name in python call.
Is there a way to access stage local variable in jenkins global pipeline, I'm trying to use the var1 value from Example stage in post always block.
// Declarative //
pipeline {
agent any
stages {
stage('Example') {
steps {
def var1 = sh 'ssh yourname#yourmachine 'grep uploadRate= /root/yourscript' '
}
}
}
post {
always {
echo 'Reading a Var1 Value' + var1
}
}
}
error:
Error when executing always post condition:
groovy.lang.MissingPropertyException: No such property: var1 for class: WorkflowScript
You cant directly call the variable which assigned in build steps in post action.
As a solution what you can do is pass the 'Example' stage result to file and then by using Environment Inject Plugin you can access the value in post action.
After installed the plugin set the file name in job configurations.
plugin setup
pipeline {
agent any
stages {
stage('Example') {
steps{
script {
sh 'date > output.txt'
}
}
}
}
post {
always {
script {
curDate = readFile 'outFile.txt'
echo "The current date is ${curDate}"
}
}
}
}
I am working on adding a jenkins Declarative pipeline for automation testing. In the test run stage i want to extract the failed tests from the log. i am using a groovy function for extracting the test result. this function is not a part of the jenkins pipeline. It is another script file. The function works fine and it build a string containing the failure details. Inside a pipeline stage i am calling this function and assinging the returned string to another variable. But when i echo the variable value it prints empty string.
pipeline {
agent {
kubernetes {
yamlFile 'kubernetesPod.yml'
}
}
environment{
failure_msg = ""
}
stages {
stage('Run Test') {
steps {
container('ansible') {
script {
def notify = load('src/TestResult.groovy')
def result = notify.extractTestResult("${WORKSPACE}/testreport.xml")
sh "${result}"
if (result != "") {
failure_msg = failure_msg + result
}
}
}
}
}
post {
always {
script {
sh 'echo Failure message.............${failure_msg}'
}
}
}
}
here 'sh 'echo ${result}'' print empty string. But 'extractTestResult()' returns a non-empty string.
Also i am not able to use the environment variable 'failure_msg' in post section it return an error 'groovy.lang.MissingPropertyException: No such property: failure_msg for class: groovy.lang.Binding'
can anyone please help me with this ?
EDIT:
Even after i fixed the string interpolation, i was getting the same
error. That was because jenkins does not allow using 'sh' inside
docker container. there is an open bug ticket in jenkins issue
board
I would suggest to use a global variable for holding the error message. My guess is that the variable is not existing in your scope.
def FAILURE_MSG // Global Variable
pipeline {
...
stages {
stage(...
steps {
container('ansible') {
script {
...
if (result != "") {
FAILURE_MSG = FAILURE_MSG + result
}
}
}
}
}
post {
always {
script {
sh "${FAILURE_MSG}" // Hint: Use correct String Interpolation
}
}
}
}

I'm trying to configure a parameter in Jenkins pipeline and then execute it within bat command:
pipeline {
agent {
label 'master'
}
parameters {
string (
defaultValue: '"someExe.exe"',
description: '',
name : 'varExe'
)
}
stages {
stage("hi") {
steps {
script {
bat '${params.varExe}'
}
}
}
}
}
Unfortunately, i'm getting this error:
'${varExe}'is not recognized as an internal or external command
For some reason, Jenkins doesn't use varExe value.
I've also tried bat '${varExe}' but still no luck.
Any ideas ?
You need to use a double quote here to replace the variable.
bat "${params.varExe}"
You have to be careful with single and double quotes. For the following example, the first one would echo someExe.exe, while the second one would throw a Bad substitution error.
pipeline {
agent any
parameters {
string (
defaultValue: '"someExe.exe"',
description: '',
name : 'varExe')
}
stages {
stage ('Test') {
steps {
script {
sh "echo '${params.varExe}'"
sh 'echo "${params.varExe}"'
}
}
}
}
}
I think for bat command should be like below
bat ''' echo %varExe% '''

When running a large Jenkins pipeline script, it can give the error:
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed: General error during class generation: Method code too large!
java.lang.RuntimeException: Method code too large!
What is the reason for this error and how can it be fixed?
This is due to a limit between Java and Groovy, requiring that method bytecode be no larger than 64kb. It is not due to the Jenkins Pipeline DSL.
To solve this, instead of using a single monolithic pipeline script, break it up into methods and call the methods.
For example, instead of having:
stage foo
parallel([
... giant list of maps ...
])
Instead do:
stage foo
def build_foo() {
parallel([
...giant list of maps...
])}
build_foo()
If you are using declarative pipeline with shared library, you may need to refactor and externalize your global variables in the new methods. Here is a full example:
Jenkinsfile:
#Library("my-shared-library") _
myPipeline()
myPipeline.groovy:
def call() {
String SOME_GLOBAL_VARIABLE
String SOME_GLOBAL_FILENAME
pipeline {
stages() {
stage('stage 1') {
steps {
script {
SOME_GLOBAL_VARIABLE = 'hello'
SOME_GLOBAL_FILENAME = 'hello.txt'
...
}
}
}
stage('stage 2') {
steps {
script {
doSomething(fileContent: SOME_GLOBAL_VARIABLE, filename: SOME_GLOBAL_FILENAME)
sh "cat $SOME_GLOBAL_FILENAME"
}
}
}
}
}
}
def doSomething(Map params) {
String fileContent = params.fileContent
String filename = params.filename
sh "echo $fileContent > $filename"
}
