How to retrieve Jenkins environment from Groovy script?-CodePudding

I am setting a Jenkins. I am programming with my pipeline using Global Pipeline Libraries to be able to increase reusability. Scripts are object oriented and in Groovy.

I don't manage to retrieve the Jenkins specific environment using my library script. I would like for instance to access:

Build_ID
Build_Number
JOB_Name
Workspace_path

I tryied to use env.WORKSPACE but it is returning a NULL. I manage to retrieve it directly in the pipeline but this is not my goal.

So the env which you are looking for can be accessible using like this in groovy script

${env.BUILD_NUMBER} ${env.JOB_NAME} ${env.WORKSPACE} ${env.BUILD_ID}

Depending on how you write your scripts, you might need to inject the Jenkins environment. For example, if you go for a more object oriented way

// vars/whatever.groovy
import ...

@Field
def myTool = new MyTool(this)

// src/.../MyTool.groovy
import ...

class MyTool {
    private final jenkins

    MyTool(steps) {
        this.jenkins = jenkins
    }

    def echoBuildNumber() {
        this.jenkins.echo(this.jenkins.env.BUILD_NUMBER)
    }
}

// Jenkinsfile
@Library(...)
node {
    echo env.BUILD_NUMBER             // echoes build number
    whatever.myTool.echoBuildNumber() // echoes build number
}
