Show a Jenkins pipeline stage as failed without fa

问题:

Here's the code I'm playing with

node {
    stage 'build'
    echo 'build'

    stage 'tests'
    echo 'tests'

    stage 'end-to-end-tests'
    def e2e = build job:'end-to-end-tests', propagate: false
    result = e2e.result
    if (result.equals("SUCCESS")) {
        stage 'deploy'
        build 'deploy'
    } else {
        ?????? I want to just fail this stage
    }
}

Is there any way for me to mark the 'end-to-end-tests' stage as failed without failing the whole job? Propagate false just always marks the stage as true, which is not what I want, but Propagate true marks the job as failed which I also don't want.

Stage takes a block now, so wrap the stage in try-catch. Try-catch inside the stage makes it succeed.

The new feature mentioned earlier will be more powerful. In the meantime:

try {
   stage('end-to-end-tests') {
     node {      
       def e2e = build job:'end-to-end-tests', propagate: false
       result = e2e.result
       if (result.equals("SUCCESS")) {
       } else {
          sh "exit 1" // this fails the stage
       }
     }
   }
} catch (e) {
   result = "FAIL" // make sure other exceptions are recorded as failure too
}

stage('deploy') {
   if (result.equals("SUCCESS")) {
      build 'deploy'
   } else {
      echo "Cannot deploy without successful build" // it is important to have a deploy stage even here for the current visualization
   }
}

Sounds like JENKINS-26522. Currently the best you can do is set an overall result:

if (result.equals("SUCCESS")) {
    stage 'deploy'
    build 'deploy'
} else {
    currentBuild.result = e2e.result
    // but continue
}

I recently tried to use vaza's answer Show a Jenkins pipeline stage as failed without failing the whole job as template for writing a function that excutes a job in an own stage named like the job name. Surprisingly it worked, but maybe some groovy experts have a look at it :)

Here is how it looks like if one of the jobs is aborted:

def BuildJob(projectName) {
    try {
       stage(projectName) {
         node {      
           def e2e = build job:projectName, propagate: false
           result = e2e.result
           if (result.equals("SUCCESS")) {
           } else {
              error 'FAIL' //sh "exit 1" // this fails the stage
           }
         }
       }
    } catch (e) {
        currentBuild.result = 'UNSTABLE'
        result = "FAIL" // make sure other exceptions are recorded as failure too
    }
}

node {
    BuildJob('job1')
    BuildJob('job2')
}

You could add a explicit fail task, such as 'sh "not exist command"' in the stage.

if (result.equals("SUCCESS")) {
   stage 'deploy'
   build 'deploy'
} else {
   try {
       sh "not exist command"
   }catch(e) {
   }
}
