I discovered a way to replicate this as well, just run the following pipeline and this will break; // Works stage( 'Stage A' ) { echo "A" } // Works stage( 'Stage B' ) { parallel a: { echo "B.A" }, b: { echo "B.B" } } // Breaks stage( 'Stage C' ) { def steps = [:] // Empty map parallel steps }

Jenny Huang added a comment - 2017-03-29 18:48 svanoort Do you have trouble reproduce it? The stage view is gone completely on the server that I have. It shows up occasionally(rarely though), but most of time, it is invisible. I have more than one build items setup and I cannot see the stage view visually in any of them. But I am pretty sure it was working fine when I set it up initially.

Sam Van Oort added a comment - 2017-04-13 02:55 jhuangjenkins I have a fix now in review now – Alexander's reproduction case provided the key to this one, plus a test suite added in the last set of workflow-api revisions.  We should have the fix in release as soon as review passes - it will require installing an updated workflow-api plugin.  Thanks!

Sam Van Oort added a comment - 2017-04-13 02:56 Impacted users can also build and install the workflow-api plugin from the PR here until it is fully released –  https://github.com/jenkinsci/workflow-api-plugin/pull/34

Sam Van Oort added a comment - 2017-04-13 14:55 The issue is purely with use of parallel steps where they contain 0 branches.  This is fixed with workflow-api 2.13, now released – please update your masters when this hits the update center in a few hours, and it should be good to go.  Thanks!

Jenny Huang added a comment - 2017-04-18 13:15 - edited svanoort Thank you for fixing the issue. Where is this workflow-api plug in? I do not see that I have that installed on my Jenkins server instance. Which plugin should I install or update to fix this?

Sam Van Oort added a comment - 2017-04-18 13:27 jhuangjenkins It will show up as "Pipeline API plugin" in the update center – workflow-api is the plugin artifact name. 

Jenny Huang added a comment - 2017-04-24 15:13 svanoort I could not find :"Pipeline API plugin" showing on my Jenkins instance . which plug-in exactly Do I have to upgrade? Can you give me the plugin name? What do you mean "update your master"? I do have a window's master and slave.
