how to access Jenkins environment variables with DSL?

Question

As the question says. I can't access it.

Tries:

#1:

def env = System.getenv()
def BUILD_NUMBER= env["BUILD_NUMBER"]

Result:

Null when I access BUILD_NUMBER

#2:

def BUILD_NUMBER= params["BUILD_NUMBER"]

Result:

Null when I access BUILD_NUMBER This solution however works for environment variables I create

Answer 1

Found out the answer: build.environment.get("BUILD_NUMBER")

Felspar

No such property: build for class: groovy.lang.Binding – Albinaalbinism

sorry can't help with that, I'm not at the same place and to now work with Jenkins anymore – Felspar

@Albinaalbinism Add the following line before it build = Thread.currentThread().executable – Lenes

Answer 2

This will work with recent versions of Jenkins and DSL plugin:

def BUILD_NUMBER = getBinding().getVariables().BUILD_NUMBER

Mediocre

Yields "Scripts not permitted to use method groovy.lang.Binding getVariables" on the corporate Jenkins I use (version unknown) – Apograph

That's a permission issue. Please check with your Jenkins administrator. – Mediocre

Answer 3

Just to let you all know I tried with

def foo = build.buildVariableResolver.resolve("FOO")
println "FOO=$foo" 

It worked. Refer the example here https://wiki.jenkins-ci.org/display/JENKINS/Groovy+plugin

In recent versions you need to do def previousBuild = currentBuild.getPreviousBuild(); def foo = previousBuild.buildVariables["YOUR_VARIABLE_NAME"] – Fremantle

@Fremantle ERROR: (script, line 1) No such property: currentBuild for class: script – Wells

Probably an old version of Jenkins / DSL / Pipeline – Fremantle

Answer 4

echo 'Build No: ' + env.BUILD_NUMBER + '. Build URL: ' + env.BUILD_URL

List of environment variables accessible via: http://HOST/PATH_TO_JENKINS/env-vars.html/

e.g., http://localhost:8888/jenkins/env-vars.html/

Only way posted here working for me in pipeline stage – Apograph

Answer 5

Jenkins ver. 2.138.2

def gitUrl = binding.variables.get("GITLAB_URL")

Answer 6

Not sure what is referenced as DSL here, but if you refer to the Job DSL plugin, you can just use "${BUILD_NUMBER}"

See https://github.com/jenkinsci/job-dsl-plugin/wiki/User-Power-Moves#access-the-jenkins-environment-variables
