jenkins acess environment variables in environment declaration

Question

So I have an environment in a Jenkins declarative pipeline script that looks something like this:

pipeline {
    environment {
        PATH1 = 'C:\Users\Administrator\Documents'
        PATH2 = '${env.PATH1}\more_stuff'
    }
    // etc...

But when I try to access PATH2 in anything, it transcribes the literal "${env.PATH1}" into it rather that the environment variable PATH1.

I have tried ${env.PATH1}, ${PATH1}, %PATH1%, but none of them work. How do I access environment variables while declaring other environment variables?

Answer 1

I will assume you are trying to use Groovy string interpolation.

Groovy string interpolation is only performed on double quoted strings, not single quoted strings.

I believe what you want is

PATH2 = "${env.PATH1}\more_stuff"
