Use “def” keyword within declarative pipeline

Question

I have declarative pipeline used and have a problem to map key-value there as I can't use "def" within pipeline. I want to achieve something like this:

def pathTag = [:]
pathTag['myKey'] = 'myValue'

I will use then "pathTag" later on as input for Jenkins plugin (Influxdb).

Has anyone idea how to do it? Thank you.

This should work, especially within `script{}`. Could you show your code? — Matthew Schuchard, May 21 '18 at 12:37

There's two places you can use def and programatic Groovy Syntax:

a script block, like script { def myvar = "I can only be seen in my script tag }

Create a function outside the pipeline tag, like so:

String hello(def who) {
  return "hi, ${who}"
}

pipeline {
  ...
}

The function outside the pipeline block may break the graphical pipeline editor in Jenkins, but if you don't use that you're probably fine.
