Jenkins can't find defined function?

Question

I wrote this to test the idea I saw on JENKINS-44085

def generateStage(String job, String targetVersion,
                  String rootVersion, Integer sleepTime=0) {
    return {
        stage("Deploying: ${job}") {
            sleep sleepTime
            println "Job: $job"
        }
    }
}

def deployProcs(targetVersion, rootVersion) {
    script {
        int sleepTime = 0
        def procs = ["proc-proc", "proc-proc-high"]
        def parallelStagesMap = procs.collectEntries {
            ["${it}" : generateStage(it, targetVersion, rootVersion, sleepTime)]
            sleepTime += 5
        }
        timestamps {
            parallel parallelStagesMap
        }
    }
}

node('linux') {
  deployProcs(10, 10)
}

But I get

java.lang.NoSuchMethodError: No such DSL method 'generateStage' found among steps.

What am I missing?

Answer 1

You are calling deployProcs(10, 10) where both parameters are type of Integer. The same integer parameters are used when calling generateStage, which parameters are typed String targetVersion and String rootVersion.

A fix is to either, call deployProcs('10', '10') or change def generateStage(String job, Integer targetVersion, Integer rootVersion, Integer sleepTime=0), or remove types from generateStage function parameters.
