How to force Jenkins to skip a downstream job if a new build is waiting in the pipeline?

Question

My build pipeline in Jenkins is broken down into three jobs:

1. Build code
2. Deploy code to environment
3. Run automated functional tests

I have set it up so that concurrent builds can occur and the build pipeline will stop a build from entering #2, if #2 or #3 is currently running for another build.

What I want to be able to do is set up Jenkins to handle when there is more than one build waiting, and #2 and #3 finish, for only the LATEST build to enter into #2 and #3.

Is there a way to do this out of the box? IF you have the book Continuous Delivery, what I'm trying to do is implement what's on p. 118 - p. 119

Answer 1

Should try one of those, under Advanced Project Options:

• Block build when upstream project is building
  (should make sure it does not cause steps 2 and 3 to get stuck in queue)

• Block build when downstream project is building
  (I know this one sounds like the opposite to your request,
  but the actual result is that you accumulate changes to a single build-cycle,
  preventing extra runs)

If this causes unwanted builds to pile-up,
please review the following links that should help you
empty the queue or kill running jobs:

• Stopping Jenkins job in case newer one is started (by malenkiy_scot)

• Purge Build Queue Plugin

• Signal killer

• Kill All the Builds (courtesy of Kohsuke Kawaguchi)

  import hudson.model.*;
  
  Hudson.instance.computers.each { c ->
    c.executors.each { e ->
       e.interrupt();
    } 
  }
