How can I access global variables (currentBuild, env, ...) from within a Shared Library?

jenkins, jenkins-pipeline

Solution

If you use the `env` variable from inside a class definition, Groovy will try to access a class variable `env`, rather than a global variable. I think you need to create a constructor and pass the `env` variable into it. For example:

package com.acme
class Lib {
    def env
}

and in your pipeline use:

 def library = Lib(env: env)

I take groovy constructor syntax from here

Problem

I'd like to access a global variable like `currentBuild`, `env`, etc. from within a shared Groovy library. Example 1 (works): ``` // vars/customStep.groovy def call() { echo env.myParameter } ``` Example 2 (doesn't work): ``` // vars/customStep.groovy class customStep implements Serializable { def call() { echo env.myParameter } } ``` Example 3 (doesn't work): ``` // src/com/acme/Lib.groovy package com.acme class Lib { def someMethod() { echo env.myParameter } } ``` I'd like to be able to access the variables in either case. How can I do this?
