title: How to parse JSON response in a built step in jenkins
body: <p>In order to industrialize the deployments of an IBM product, I'm going to use its REST API interfaces.
  I plan to use jenkins in order to orchestrate the calls to the REST APIs.
  I'm still wondering if it's a good idea...?
  If so, is there any way to simply parse the JSON responses in order to be able to make some conditions in the steps?
  Thanks.</p>
