I've recently ported a whole bunch of independent Jenkinsfiles into one Jenkinsfile that uses matrix to go over a set of platforms. Below the stages block, I would use post to detect if a build was fixed or failed and notify Slack. Since porting to use a matrix pipeline, the post fixed block runs upon any success if any of the previous matrix entries failed in the previous build, leading to lots of noisy reporting. I've reproduced this with a minimal example Jenkinsfile:
pipeline {
  agent none
stages {
    stage('Build All Platforms') {
      matrix {
        axes {
          axis {
            name 'PLATFORM'
            values 'A', 'B'
          }
        }
        agent any
        stages {
          stage('Update') {
            steps {
              echo 'Updating'
            }
          }
          stage('Build') {
            environment {
              failure = "${new Random().nextInt(2)}"
            }
            steps {
              echo "Building. Expect failure = ${failure}"
              bat "exit /b ${failure}"
            }
          }
        }
        post {
          success {
            echo 'Success'
          }
          fixed {
            echo 'Fixed'
          }
          failure {
            echo 'Failed'
          }
        }
      }
    }
  }
}
This just has 2 platforms and upon build each platform will have a 50% chance of succeeding.
With the following build results:
- Build #1: Platform A fails, platform B succeeds
- Build #2: Platform A fails, platform B succeeds
I see build #2 will claim platform B's build was "fixed" even though it succeeded in the previous build. This seems to be because platform A failed in the previous build. I would expect the post fixed block to not run at all for platform B in build #2.
Is this a known issue? Am I just misunderstanding how to use the post block within the context of a matrix pipeline? Is there a workaround you can suggest?
