Access Stage results in Workflow/ Pipeline plugin

Question

I have a pipeline with different stages. I want the current job to check how many stages have passed in the previous build and log it in the console?

You definitely could use Pipeline REST API Plugin, for me it was available out of the box with Jenkins 2.13.

By parsing the resulting JSON you could get the status of the stage similarly to what you expect. For the api call I personally use http_request plugin.

From the documentation GET /job/:job-name/:run-id/wfapi/describe returns:
