Build details of pipeline job via API

[Graham Lyons]

Hi,

I'm trying to get information about running builds on Jenkins agents, with and without pipelines. 'Old-style' jobs show up just fine but pipelines only ever appear as placeholder tasks:

{

   "currentExecutable": {

     "_class": "org.jenkinsci.plugins.workflow.support.steps.ExecutorStepExecution$PlaceholderTask$PlaceholderExecutable"

   },

   "currentWorkUnit": {

    },

   "idle": false,

   "likelyStuck": false,

   "number": 1,

   "progress": 84

 }

I'm using Jenkins ver. 2.19.1 but, looking at the source code, I don't see any changes relating to this in later versions. I could be wrong about that of course.

Is this expected? Is there a way to make it behave differently? How does the /ajaxExecutors endpoint get its data?

If anyone can help then I'd really appreciate it.

Thanks,

Graham
