I'm trying to do something that I feel should be simple to do, but I can't figure out how.
Basically I have a Jenkins master (running on Linux) and two slaves, one on Windows and the other on macOS.
I want to build my project on all 3 platforms and run GTest tests on all 3 platforms too.
I can build and run the test, but the junit step doesn't seem to collect any test results.
I tried to put the post block everywhere, but it just doesn't work. If I try to put the post block in the Test stage or as a sibling of stages, I get the following error:
Required context class hudson.FilePath is missing
Perhaps you forgot to surround the code with a step that provides this, such as: node
which is caused by agent none - the post block doesn't know where to run.
So I tried to put the post block inside the node block in my parallel step for the Test stage, but it doesn't seem to do anything - it doesn't even show up in the console output.
Here's my Jenkinsfile:
pipeline {
agent none
stages {
stage ('Clean') {
steps {
parallel (
"linux" : {
node ("linux") {
dir("build") {
deleteDir()
writeFile file:'dummy', text:'' // Creates the directory
}
}
},
"windows" : {
node('windows') {
dir("build") {
deleteDir()
writeFile file:'dummy', text:'' // Creates the directory
}
}
},
"mac" : {
node('mac') {
dir("build") {
deleteDir()
writeFile file:'dummy', text:'' // Creates the directory
}
}
}
)
}
}
stage ('Build') {
steps {
parallel (
"linux" : {
node ("linux") {
checkout scm
dir("build") {
sh '/opt/cmake/bin/cmake .. -DCMAKE_BUILD_TYPE=Release'
sh 'make'
}
}
},
"windows" : {
node('windows') {
checkout(changelog: false, scm: scm) // Changelog to false, otherwise Jenkins shows duplicates. Only linux (the Jenkins master) has the changelog enabled.
dir("build") {
bat 'cmake .. -G "Visual Studio 15 2017 Win64" -DCMAKE_PREFIX_PATH=C:/Qt/5.9.1/msvc2017_64'
bat "\"${tool 'MSBuild'}\" project.sln /p:Configuration=Release /p:Platform=\"x64\" /p:ProductVersion=1.0.0.${env.BUILD_NUMBER} /m"
}
}
},
"mac" : {
node('mac') {
checkout(changelog: false, scm: scm) // Changelog to false, otherwise Jenkins shows duplicates. Only linux (the Jenkins master) has the changelog enabled.
dir("build") {
sh 'cmake .. -DCMAKE_PREFIX_PATH=/usr/local/Cellar/qt/5.9.1 -DCMAKE_BUILD_TYPE=Release'
sh 'make'
}
}
}
)
}
}
stage ('Test') {
steps {
parallel (
"linux" : {
node ("linux") {
dir('Build') {
sh './bin/project-tests --gtest_output=xml:project-tests-results.xml'
// Add other test executables here.
}
post {
always {
junit '*-tests-results.xml'
}
}
}
},
"windows" : {
node('windows') {
dir("build") {
bat 'tests\\project\\Release\\project-tests --gtest_output=xml:project-tests-results.xml'
// Add other test executables here.
}
post {
always {
junit '*-tests-results.xml'
}
}
}
},
"mac" : {
node('mac') {
dir("build") {
sh './bin/project-tests --gtest_output=xml:project-tests-results.xml'
// Add other test executables here.
}
post {
always {
junit '*-tests-results.xml'
}
}
}
}
)
}
}
}
}
What am I doing wrong?
post{} block should only follow steps{} or parallel{} (for parallel stages) to take effect.
If you require post to be executed in a node environment, you should provide a node to the entire stage (agent{} statement).
You could try to use parallel stages execution. Also I'd suggest to use functions to shorten the code.
Something like this:
void Clean() {
dir("build") {
deleteDir()
writeFile file:'dummy', text:'' // Creates the directory
}
}
void SmthElse(def optionalParams) {
// some actions here
}
pipeline {
agent none
options {
skipDefaultCheckout(true) // to avoid force checkouts on every node in a first stage
disableConcurrentBuilds() // to avoid concurrent builds on same nodes
}
stages {
stage('Clean') {
failfast false
parallel {
stage('Linux') {
agent {label 'linux'}
steps {Clean()}
post {
// post statements for 'linux' node
SmthElse(someParameter)
}
}
stage('Windows') {
agent {label 'windows'}
steps {Clean()}
post {
// post statements for 'windows' node
}
}
stage('MacOS') {
agent {label 'mac'}
steps {Clean()}
post {
// post statements for 'mac' node
}
}
}
post {
// Post statements OUTSIDE of nodes (i.e. send e-mail of a stage completion)
}
}
// other stages (Build/Test/Etc.)
}
}
Alternatively you can use node in post statements:
stage('Test') {
steps {
// your parallel Test steps
}
post {
always {
script {
parallel (
"linux" : {
node('linux') {
// 'linux' node post steps
}
},
"windows" : {
node('windows') {
// 'windows' node post steps
}
}
// etc
)
}
}
}
}
