scripted pipeline not updating build result

currentBuild.result not updating

Jenkins in scripted pipeline is not updating currentBuild.result or currentBuild.currentResult on failure

currentBuild.result is null
currentBuild.getResult() is null
currentBuild.currentResult is 'SUCCESS'
currentBuild.rawBuild.result is null
currentBuild.rawBuild.getResult() is null

must explicitly set result

problem Jenkinsfile

node('linux') {
  try {
    stage('fail') {
      sh "exit 1"
    }
  } finally {
    println currentBuild.currentResult
    // expected: "FAILED"
    // actual  : "SUCCESS"
  }
}

solution Jenkinsfile

node('linux') {
  try {
    stage('fail') {
      sh "exit 1"
    }
  } catch(e) {
    currentBuild.result = 'FAILED'
    throw e
  } finally {
    println currentBuild.currentResult
    // expected: "FAILED"
    // actual  : "FAILED"
  }
}

hello Stephen
Looking at your example and the one from: https://plugins.jenkins.io/logstash/ I can see that the result key with its value are part of the json payload, is it possible to do the same with other currentBuild variables like: startTimeInMillis, duration, etc. I've been trying to accomplish that with no luck, not sure If you can point me in the right direction. Thank you very much!
