Contra Olivier Lamy’s comment there I consider this a bug. Blue Ocean should pay attention to the build metadata as provided by official Pipeline APIs and may not make assumptions about the mechanism used to run a build, except insofar as that is intrinsically required for a certain feature. (For example, a stage restart button should only appear next to a Declarative stage, because the feature of restarting a stage is tied to Declarative semantics.)

Regardless of how the issue is classified, the question of whether it will be fixed or not depends entirely on the development team’s time and priorities.

Thanks Jesse Glick and An Tran for digging into this more! I personally am not concerned whether or not this is a bug or improvement, as long as it is fixed . It does sound a lot like a bug to me, but I do understand the argument for it being an improvement. Whatever the best path to resolution is will be fine with me.

Based on the tickets An Tran linked above, it looks like others desire this functionality as well.

I am also stuck in the same situation, where I need to use scripted parallel block within declarative and the blueocean view is doesn't display the stages for scripted block correctly.

Here I share three code examples (bottom of this comment)

1. declarative parallel within declarative pipeline
2. scripted parallel within scripted pipeline
3. scripted parallel within declarative pipeline

The first two get visualized as expected.

The third one gets a messed up visualization starting at the parallel part, i.e. also affects the next non-parallel stage.

The code

• declarative parallel within declarative pipeline

  pipeline {
      agent("none")
      stages {
          stage("prepare") {steps {echo "prepare"}}
          stage("build") {steps {echo "build"}}
          stage("test") {
              parallel {
                  stage("linux") {
                      stages {
                          stage("install") {steps {echo "installing in linux"}}
                          stage("test") {steps {echo "testing in linux"}}
                      }
                  }
                  stage("windows") {
                      stages {
                          stage("install") {steps {echo "installing in windows"}}
                          stage("test") {steps {echo "testing in windows"}}
                      }
                  }
                  stage("mac") {
                      stages {
                          stage("install") {steps {echo "installing in mac"}}
                          stage("test") {steps {echo "testing in mac"}}
                      }
                  }
              }
          }
          stage("cleanup") {steps {echo "cleanup"}}
      }
  }
  

• scripted parallel within scripted pipeline

  stage("prepare") {echo "prepare"}
  stage("build") {echo "build"}
  stage("test") {
      parallel ([
          "linux": {
              stage("install") {echo "installing in linux"}
              stage("test") {echo "testing in linux"}
          },
          "windows": {
              stage("install") {echo "installing in windows"}
              stage("test") {echo "testing in windows"}
          },
