问题
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 ${result}'' print empty string. But 'extractTestResult()' returns a non-empty string.
Also i am not able to use the environment variable 'failure_msg' in post section it return an error 'groovy.lang.MissingPropertyException: No such property: failure_msg for class: groovy.lang.Binding'
can anyone please help me with this ?
EDIT:
Even after i fixed the string interpolation, i was getting the same error. That was because jenkins does not allow using 'sh' inside docker container. there is an open bug ticket in jenkins issue board
回答1:
I would suggest to use a global variable for holding the error message. My guess is that the variable is not existing in your scope.
def FAILURE_MSG // Global Variable
pipeline {
...
stages {
stage(...
steps {
container('ansible') {
script {
...
if (result != "") {
FAILURE_MSG = FAILURE_MSG + result
}
}
}
}
}
post {
always {
script {
sh "${FAILURE_MSG}" // Hint: Use correct String Interpolation
}
}
}
}
