Declarative pipeline when condition in post

Question

As far as declarative pipelines go in Jenkins, I\'m having trouble with the when keyword.

I keep getting the error No such DSL method \'when\' found a

Ran into the same issue with post. Worked around it by annotating the variable with @groovy.transform.Field. This was based on info I found in the Jenkins docs for defining global variables.

e.g.

#!groovy

pipeline {
    agent none
    stages {
        stage("Validate") {
            parallel {
                stage("Ubuntu") {
                    agent {
                        label "TEST_MACHINE"
                    }
                    steps {{
                        sh "run tests command"
                        recordFailures('Ubuntu', 'test-results.xml')
                        junit 'test-results.xml'
                    }
                }
            }
        }
    }
    post { 
        unsuccessful { 
            notify()
        }
    }
}

// Make testFailures global so it can be accessed from a 'post' step
@groovy.transform.Field
def testFailures = [:]

def recordFailures(key, resultsFile) {
    def failures = ... parse test-results.xml script for failures ...
    if (failures) {
        testFailures[key] = failures
    }
}

def notify() {
    if (testFailures) {
        ... do something here ...
    }
}
