Jenkins pipeline : select nodejs version (+ python version)

Question

I\'m facing an issue with a Jenkins pipeline in a Jenkinsfile. I have 4 different nodeJs versions on my Jenkins instance. I would like to choose which one I\'m going to use in m

Answer 1

So. This is a problem from "EnvInject" plugin: https://issues.jenkins-ci.org/browse/JENKINS-26583

My workaround #4 above is the correct solution if you want to keep EnvInject.

env.NODE_HOME="${tool 'Node 6.x'}"
env.PATH="${env.NODE_HOME}/bin:${env.PATH}"
sh 'npm -version'

Otherwise, removing EnvInject plugin is also a good solution when possible.

Answer 2

how about using docker image with the specific version of node and/or python in your Jenkins pipeline? this would be a clean solution since you will only need to install docker on the build machine and not side-by-side versions of python.

pipeline {
     agent {
                label 'slave-machine'
    }
    environment {
        NODE_HOME = tool name: 'Node 10.13.0', type: 'jenkins.plugins.nodejs.tools.NodeJSInstallation'
    }
    stages { 
        stage('test') {]
            steps {
               script {
                   env.PATH="${env.NODE_HOME}/bin:${env.PATH}"
                   sh 'node -v'
                   sh 'echo $NODE_HOME'
               }
            }
        }
    }
}
