Portable Maven launch

[Jochen Wiedmann]

Hi,

I've got a pipeline file, that should be executable on a Windows build server, and on a Linux build server. The pipeline is launching Maven as follows:

On Linux:

    sh "mvn <MAVEN_OPTIONS>"

But on Windows, this appears not to work, so I've got to use:

   bat "mvn.cmd <MAVEN_OPTIONS>" 

Right now, I can use either of these steps, so have to choose between Windows, and Linux. Is there any possibility to get this portable? I am thinking something like

   if (isWindows()) {

       bat "mvn.cmd <MAVEN_OPTIONS>" 

   } else {

    sh "mvn <MAVEN_OPTIONS>"

   }

Thanks,

Jochen

Thanks,

sounds like what I was looking for. But then: Any ideas, what's wrong in my script?

pipeline {

    agent any

    tools { 

        maven 'Maven3' 

        jdk 'Java8' 

    }

    stages {

        stage ('afw-core') {

            steps {

                withMaven(

                     // Maven installation declared in the Jenkins "Global Tool Configuration"

                     maven: 'Maven3',

                    // Use `$WORKSPACE/.repository` for local repository folder to avoid shared repositories

                    mavenLocalRepo: '.repository',

                ) {

    if (isUnix()) {

            sh 'mvn -fafw/afw-core/pom.xml -Pjacoco -Dmaven.test.failure.ignore=true clean install'

} else {

            bat 'mvn.cmd -fafw/afw-core/pom.xml -Pjacoco -Dmaven.test.failure.ignore=true clean install'

}

                }

            }

        }

        stage ('afw-bootstrap') {

            steps {

                withMaven(

                     // Maven installation declared in the Jenkins "Global Tool Configuration"

                     maven: 'Maven3',

                    // Use `$WORKSPACE/.repository` for local repository folder to avoid shared repositories

                    mavenLocalRepo: '.repository',

                ) {

    if (isUnix()) {

            sh 'mvn -fafw/afw-bootstrap/pom.xml -Pjacoco -Dmaven.test.failure.ignore=true clean install'

} else {

            bat 'mvn.cmd -fafw/afw-bootstrap/pom.xml -Pjacoco -Dmaven.test.failure.ignore=true clean install'

}

                }

            }

        }

    }

}

The error message I am getting:

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:

WorkflowScript: 17: Expected a step @ line 17, column 9.

                                    if (isUnix()) {

           ^

WorkflowScript: 34: Expected a step @ line 34, column 9.

                                    if (isUnix()) {

           ^

The if statement is not a pipeline step. It has to be wrapped in a script block:
