Complex enum are not supported in Shared Library

XMLWordPrintable

      I've noticed that when I override a method for a particular enum value, my pipeline fails

      I've reproduce the error with the following elements. I declare an enum in a dedicated class file

      enum Day {
    SUNDAY(false) {
        String aName() {
            return "Easy day !"
        }
    },
    MONDAY(true),

    boolean workingDay

    Day(boolean workingDay) {
        this.workingDay = workingDay
    }

    String aName() {
        return "Thought day !"
    }
}

      Then in a pipeline script I'm using it

      import com.jenkins.Day
node {
    println "${Day.MONDAY} is a working day ? ${Day.MONDAY.isWorkingDay()}"
    println "${Day.MONDAY} is ${Day.MONDAY.aName()}"
    println "${Day.SUNDAY} is ${Day.SUNDAY.aName()}"
}

      When I run this pipeline I can see the following error

      org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException: unclassified field java.lang.Class MONDAY

      Besides I've noticed a different behaviour when I'm declaring such enum directly in the pipeline script, like

      enum Day {
    SUNDAY(false) {
        String aName() {
            return "Easy day !"
        }
    },
    MONDAY(true),

    boolean workingDay

    Day(boolean workingDay) {
        this.workingDay = workingDay
    }

    String aName() {
        return "Thought day !"
    }
}


node {
    println "${Day.MONDAY} is a working day ? ${Day.MONDAY.isWorkingDay()}"
    println "${Day.MONDAY} is ${Day.MONDAY.aName()}"
    println "${Day.SUNDAY} is ${Day.SUNDAY.aName()}"
}

      I can see a different error

      [Pipeline] {
[Pipeline] echo
MONDAY is a working day ? true
[Pipeline] echo
MONDAY is Thought day !
[Pipeline] End of Pipeline

      I suspect an issue with CPS transformation or something like which does not support this tricky enum
