Jenkins Pipeline NotSerializableException: groovy.json.internal.LazyMap

Question

Solved: Thanks to below answer from S.Richmond. I needed to unset all stored maps of the groovy.json.internal.LazyMap type whi

Answer 1

I found more easy way in off docs for Jenkins pipeline

Work example

import groovy.json.JsonSlurperClassic 


@NonCPS
def jsonParse(def json) {
    new groovy.json.JsonSlurperClassic().parseText(json)
}

@NonCPS
def jobs(list) {
    list
        .grep { it.value == true  }
        .collect { [ name : it.key.toString(),
                      branch : it.value.toString() ] }

}

node {
    def params = jsonParse(env.choice_app)
    def forBuild = jobs(params)
}

Due to limitations in Workflow - i.e., JENKINS-26481 - it's not really possible to use Groovy closures or syntax that depends on closures, so you can't > do the Groovy standard of using .collectEntries on a list and generating the steps as values for the resulting entries. You also can't use the standard > Java syntax for For loops - i.e., "for (String s: strings)" - and instead have to use old school counter-based for loops.
