title: How to retrieve jenkins build pipeline number?
body: <p>In Jenkins I would like to build my test environment based on the "Build Pipeline Number" to make tests and deployment repeatable (on the same source version), but I didn't find any environment variable to retrieve this number. I tried to use the BUILD_ID but it is different for each job (downstream project).</p>
  
  <p>Is it possible to retrieve the Build Pipeline Number? Or is there any other control number that I can use that is the same for all the jobs (increases on a new build)?</p>
