[JENKINS-67875] Pipeline matrix stages do not render

[jenkins-infra-bot]

I have encountered a repeatable issue with build visualization when using matrix in declarative syntax. There is already a bug JENKINS-63952 created under the blueocean-plugin in 2020 that appears to be the same issue but the problem affects the job's "Stage View" as well as Blue Ocean, therefore I believe it would be more appropriate to address here. Sorry if this is considered a duplicate for the same issue.

Here is the example pipeline posted by Marcel in the blueocean case:

PROPS = [
    'a': true,
    'b': false,
    'c': true
]

pipeline {
    agent none
    stages {
stage('Main') {
    matrix {
axes {
    axis {
name 'APP'
values 'a', 'b', 'c'
    }
}
stages {
    stage('first') {
when {
    expression {
return PROPS[APP]
    }
}
steps {
    echo APP
}
    }
}
    }
}
    }
}

And screenshots with the incorrect visualization:

In Blue Ocean, logs for axis value 'a' are omitted/unavailable:

In the Stage View, logs for the axis value 'a' are not reported:

However the console log includes the output from axis value 'a':

 

Examining the console output is not practical for larger/noisy pipelines and I have not found a workaround for my team's particular case. Even though the stages do run, it seems like this is a significant gap in functionality because of the extra effort required to analyze the behavior of a build.

Does a workaround exist? Adding "sleep" instructions (as mentioned in JENKINS-63952) did not have an impact in my team's situation.
