Sprint:Pipeline - December
Hi,
Since I update the Pipeline: Declarative plugin to version 1.2.5 the post action is no more executed.
This can be reproduced using this Jenkinsfile:
pipeline {
agent none
stages {
stage('Parallel') {
parallel {
stage('Child 1') {
agent any
steps { echo 'Child 1' }
}
stage('Child 2') {
agent any
steps { echo 'Child 2' }
}
}
post {
always {
echo 'Post'
}
}
}
}
}
It works as expected using the version 1.2.4 of the plugin.
Here a Dockerfile that helped me to see the difference of the behavior with the 2 versions:
FROM jenkins/jenkins:lts USER jenkins # Install plugins # fixed version of pipeline-model-definition-plugin because post action job is no more executed with 1.2.5 RUN /usr/local/bin/install-plugins.sh pipeline-model-definition:1.2.4 mock-slave workflow-aggregator blueocean hipchat ssh-slaves gradle pipeline-maven

[FIXED JENKINS-48266] Skip post for skipped parallel stages
The JENKINS-47928 fix was actually not right - it disabled calling
post entirely for parallel parent stages if they weren't the source of
an error themselves. That means they weren't called at all if there
was no failure!
The proper fix is to track whether a parallel parent stage has been
skipped, and if so, skip post execution as well. Which is what's done
here. Tada.
So the issue is that the fix for JENKINS-47928 was too heavy a hammer - it didn't call post for a parallel parent if there wasn't an error specific to that parallel parent (or its children, obviously). That means it wasn't run for cases where no failure had been encountered at all...which was not ideal. =)
So I think I've fixed it by tracking when a parallel parent is skipped due to earlier error/unstable/when and not running the post if the parent was skipped. This doesn't do anything about some other similarish cases - i.e., if one of your parallel child stages fails before another parallel child stage completes successfully, the post failure will stick in for the successful child stage, since the build as a whole is a failure by then - but that will have to wait for more granular status controls.
Bulk closing resolved issues.
