Jenkinsfile Accessing variables from shared libraries

[Kernel Panic]

Hello there

Maybe this is a very basic question, but am not being able to access a global variable

from a shared library from a Jenkinsfile

under vars I defined something like this

globalVars.groovy

class Vars () {

    def CustomMessage = "This is a new deployment"

}

from my Jenkinsfile

library identifier: 'globalVars@master', \
                     retriever: modernSCM([$class: 'GitSCMSource', \
                                credentialsId: 'tfsservice', \
                                remote: 'http://myrepo.com', \
                                traits: [gitBranchDiscovery()]])

pipeline {

stages {
    stage('Do Some Stuff') {
      steps {
        script {

           sh 'echo ${CustomMessage}'

          }
        }
      }
    }

}

But the above returns nothing, what am I doing wrong?

Thanks

Regards

I see several problem

1. using ' will not expand the parameters is your call should be sh "echo ${CustomMessage}"
2. CustomMessage is declared within the class Vars(), so you cannot access it

You could implement a getter an then do something like this "echo ${globalVars.getCustomMessage()}"

Maybe others have better ideas...?

In my case, I do the following. I have a GlobalVars.groovy file with below content.

#!/usr/bin/env groovy
package com.<companyName>.<ProductName>;

public class GlobalVars {
   static String myVar = ""
}

Then in my Shared Library class, I use it like below.

GlobalVars.myVar = ""

Try it like this and check. Here, I have declared the class as Public and the variable as static. That's the only difference.

Hello

Defining a global class worked for me, at least did what I wanted to do,

Thanks you very much for your time and support

Hello

Is there a way to access those variables from as sh command from the script section?

for example this works:

script {
                      echo GlobalVariables.MyVariable

                    }

but the same with sh does not, that just echos GlobalVariables.MyVariable and not the variable content.

script {

              sh  ' echo GlobalVariables.MyVariable'

                    }

Thanks

Regards
