I am getting the following error when trying to run my jenkins job. Any help would be much appreciated

java.lang.IllegalArgumentException: Expected named arguments but got

My code is:

node("dvsacvsmgmt") {



    stage("Build") {



        def buildJobs = 

        for (BACKEND_SERVICE in BACKEND_SERVICES) {

            SVC = BACKEND_SERVICE.replaceAll('-','_')



            switch (BRANCH_SVC) {

                case ["develop","master"]:

                    def buildJob = {

                        build "${ROOT_FOLDER}/2_Build/Backend/${SVC}/job_build_backend_" + BRANCH_SVC + "_" + SVC +".groovy"

                    }

                    buildJobs.add(buildJob)

                break

                default:

                    def buildJob = {

                        build "job_${SVC}": "${ROOT_FOLDER}/2_Build/Backend/${SVC}/job_build_backend_" + BRANCH_SVC + "_" + SVC +".groovy",

                                parameters: [gitParameter(name: "BRANCH", value: BRANCH_SVC)]

                    }

                    buildJobs.add(buildJob)

                break

            }

        }

        parallel(buildJobs)

    }

}

NOTE: My variables are defined at the top,

BRANCH, BRANCH_SVC, ROOT_FOLDER, BACKEND_SERVICES

You see this exception because buildJobs in your example is a list of closures and it should be a map instead. It would make sense to use backend service name as a key for the map you pass to parallel() method. Consider the following changes to your code:

node("dvsacvsmgmt") {

    stage("Build") {



        def buildJobs = [:]

        for (BACKEND_SERVICE in BACKEND_SERVICES) {

            SVC = BACKEND_SERVICE.replaceAll('-','_')



            switch (BRANCH_SVC) {

                case ["develop","master"]:

                    def buildJob = {

                        build "${ROOT_FOLDER}/2_Build/Backend/${SVC}/job_build_backend_" + BRANCH_SVC + "_" + SVC +".groovy"

                    }

                    buildJobs.put(BACKEND_SERVICE, buildJob)

                break

                default:

                    def buildJob = {

                        build "job_${SVC}": "${ROOT_FOLDER}/2_Build/Backend/${SVC}/job_build_backend_" + BRANCH_SVC + "_" + SVC +".groovy",

                                parameters: [gitParameter(name: "BRANCH", value: BRANCH_SVC)]

                    }

                    buildJobs.put(BACKEND_SERVICE, buildJob)

                break

            }

        }

        parallel(buildJobs)

    }

}

It invokes

buildJobs.put(BACKEND_SERVICE, buildJob)

instead

buildJobs.add(buildJob)

to create a map that is seen as named arguments in parallel method call.
