Jenkins:
Core 2.126
Experimental level plugins all up to date
Plus Declarative running not-even-merged PR 228 level code
Summary
I made a mistake and ended up with a stage containing two steps blocks. When it ran, I got two error messages. The first made total sense, but the second error barked at me about Duplicate parallel branch name: "default". It looked out of place, since there's no stage called default.
Steps to recreate
1. Fire up your favorite Jenkins instance
2. Build this fork/branch of Declarative (PR 228) and pop it on. I did it via
- git checkout abayer/jenkins-45455
- mvn clean install -DskipTests=true
- Upload the resulting .hpi files to my instance
- Restart
3. Run the following Pipeline. This will recreate via actually running it, or by using the CLI.
pipeline { agent any stages { stage('Only the duplicate steps problem') { steps { echo "NOT SEQUENTIAL" } steps { echo "NOT SEQUENTIAL" } } } }
Results
Error messages as follows:

It's the second of the two errors that looked strange, since there's no branch called default.
