Summary
I accidentally ended up with a Jenkinsfile with an incorrect sequential flow in it. When I tried to run it, instead of a clear explanation of what I'd done wrong, I got a NullPointerException back.
Opening this as a Minor because this is an operator error kind of problem. Figured you'd want to at least see it though, considering it's a NPE.
Steps to recreate
1. Use this pipeline. You can use it in an inline job, store it on SCM somewhere, or use the CLI.
pipeline {
agent any
stages {
stage('PARALLEL-WRAPPER') {
parallel {
stages {
stage('file-1') {
steps {
sh "touch file-1"
}
}
stage('file-2') {
steps {
sh "touch file-2"
}
}
}
stage('Contains Sequentials') {
stages {
stage('ls') {
steps {
sh "ls"
}
}
stage('ls') {
steps {
sh "ls file-2"
}
}
}
}
}
}
}
}
2. Run it in whatever your preferred way is. Here it is from the CLI:
