I am trying to get a Jenkins (2.204.2) declarative pipeline to run parallel stages generated into a map on different machines. I am aware it can be done by mixing in the script block and I have done it that way in the past, but from documentation and other Stack____ questions I cannot figure out why this format does not work.
I have stripped everything down as far as possible and I am trying to just create the map statically outside the pipeline to figure out the syntax I need.
#!/usr/bin/env groovy
def map = [:]
map['Passed Stage'] = {
stage("Passed Map Inner Stage"){
agent{ label "nodeLabel" }
steps{
echo "PASSED MAP STEP"
}
}
}
pipeline {
agent { label "nodeLabel" }
stages {
stage("Non map stage"){
agent{ label "nodeLabel" }
steps{
echo "NON MAP STEP"
}
}
stage("Direct Map Outer Parallel Stage"){
parallel{ direct :
stage("Direct Map Inner Stage"){
agent{ label "nodeLabel" }
steps{
echo "DIRECT MAP STEP"
}
}
}
}
stage("Passed Map Outer Parallel Stage"){
parallel{ map }
}
}
}
The first two stage methods work if I comment out the mapped one but "Passed Map Outer Parallel Stage" always fails with:
Running in Durability level: MAX_SURVIVABILITY

The stage format seems fine from everything I've spent reading all day, and passing the same stage directly to parallel outside the map works fine.
What am I missing here? why won't parallel accept my map? Does declarative parallel only accept stages statically passed? Is my Jenkins version too low?
