What Operating System are you using (both controller, and any agents involved in the problem)?
Windows, Windows
Reproduction steps
pipeline {
agent none
stages {
stage('parallel') {
steps {
script {
stage ("config") {
echo "config"
}
def tasks = [
'stage 1': {
stage("hello") {
echo "Hello 1"
}
stage("world") {
echo "world 1"
}
},
'stage 2': {
stage("hello") {
echo "hello 2"
}
stage("world") {
echo "world 2"
}
}
]
parallel tasks
}
}
}
}
}Expected Results
Actual Results
Anything else?
Graph is fixed after moving "config" stage around
Here is working pipeline
pipeline {
agent none
stages {
stage ("config") {
steps {
echo "config"
}
}
stage('parallel') {
steps {
script {
def tasks = [
'stage 1': {
stage("hello") {
echo "Hello 1"
}
stage("world") {
echo "world 1"
}
},
'stage 2': {
stage("hello") {
echo "hello 2"
}
stage("world") {
echo "world 2"
}
}
]
parallel tasks
}
}
}
}
