Help with groovy syntax

[kurr...@gmail.com]

Hello

I had a jenkinsfile which worked perfectly, but after updating it no longer works.

Old Jenkinsfile

#!/usr/bin/groovy

@Library('github.com/fabric8io/fabric8-pipeline-library@master')

def failIfNoTests = ""

try {

  failIfNoTests = ITEST_FAIL_IF_NO_TEST

} catch (Throwable e) {

  failIfNoTests = "false"

}

def itestPattern = ""

try {

  itestPattern = ITEST_PATTERN

} catch (Throwable e) {

  itestPattern = "*KT"

}

def versionPrefix = ""

try {

  versionPrefix = VERSION_PREFIX

} catch (Throwable e) {

  versionPrefix = "1.0"

}

def canaryVersion = "${versionPrefix}.${env.BUILD_NUMBER}"

//def utils = new io.fabric8.Utils()

node {

  def envProd = 'shiftwork-production'

  checkout scm

  kubernetes.pod('buildpod')

  .withNewContainer()

  .withImage('jhipster/jhipster')  

      .withPrivileged(true)

      .withHostPathMount('/var/run/docker.sock','/var/run/docker.sock')

      .withEnvVar('DOCKER_CONFIG','/home/jenkins/.docker/')

      .withSecret('jenkins-docker-cfg','/home/jenkins/.docker')

      .withSecret('jenkins-maven-settings','/root/.m2')

      .withServiceAccount('jenkins')

      .inside {

    stage 'Canary Release'

    mavenCanaryRelease{

      version = canaryVersion

    }

    stage 'Integration Test'

    mavenIntegrationTest{

      environment = 'Testing'

      failIfNoTests = localFailIfNoTests

      itestPattern = localItestPattern

    }

    stage 'Rolling Upgrade Production'

    def rc = readFile 'target/classes/kubernetes.json'

    kubernetesApply(file: rc, environment: envProd)

  }

}

New Syntax

So I'm trying to replace with the below groovy. But this results in an error. Im not familiar with groovy. The old DSL style syntax was very easy to read and write. The below, newer, syntax.

podTemplate(label: label, serviceAccount: 'jenkins', containers: [

         [name: 'maven', image: 'fabric8/maven-builder', command: 'cat', ttyEnabled: true, 

         envVars: [                

                 [key: 'DOCKER_CONFIG', value:'/home/jenkins/.docker/'],

                 ],

         [name: 'jnlp', image: 'iocanel/jenkins-jnlp-client:latest', command:'/usr/local/bin/start.sh', args: '${computer.jnlpmac} ${computer.name}', ttyEnabled: false,

                envVars: [

                 [key: 'DOCKER_HOST', value: 'unix:/var/run/docker.sock']

                 ]

                 ]

                 ],

         volumes: [

                [$class: 'PersistentVolumeClaim', mountPath: '/home/jenkins/.mvnrepository', claimName: 'jenkins-mvn-local-repo'],

                [$class: 'SecretVolume', mountPath: '/home/jenkins/.m2/', secretName: 'jenkins-maven-settings'],

                [$class: 'SecretVolume', mountPath: '/home/jenkins/.docker', secretName: 'jenkins-docker-cfg'],

                [$class: 'HostPathVolume', mountPath: '/var/run/docker.sock', hostPath: '/var/run/docker.sock']

        ]])

Error

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 34: Unexpected node type: EXPR found when expecting type: LABELED_ARG at line: 34 column: 10. File: WorkflowScript @ line 34, column 10.
           	[name: 'maven', image: 'fabric8/maven-builder', command: 'cat', ttyEnabled: true, 
            ^

Also, how do I write 
.withImage('jhipster/jhipster')
in the new syntax?

Thanks
