How to set "Environment variables" in "Global properties" of global Jenkins configuration programmatically?

[mr]

Hi!

I have some environment variables as List of key-value pairs within the "Global properties" section of the global Jenkins configuration.

I wonder if it is possible to change such a environment variables programmatically, for example by means of a Groovy script?

Regards,

mr

Hi Folks!

Do anybody have an idea how to set/change the variables within a Groovy script?

Regards!

I use the following script to inject a username and password:

usernamePassword = build.getEnvironment(null)[secret]
def (username, password) = usernamePassword.split(':')

e = new hudson.EnvVars()
e.put(secret + '_USERNAME', username)
e.put(secret + '_PASSWORD', password)
build.environments.add(hudson.model.Environment.create(e))

[mr]

Thanks for the answer!

Where do you inject the username and password? I think you do it into the current build.

But I want to inject a new variable or change an existing variable (like e.g. username or password) into the global configuration, thus next time when I go into the Global Jenkins Configuration UI, I could see the username or password in the section "Global properties".

Is this possible? Is there a package like "hudson.configuration.global" within the API which would allow me to change the environment variable within the global properties jenkins configuration section?

[mr]

Does anybody have an idea???

[Jonathann Zenou]

I seem to have the same issue.

Does someone know what to do to alter a global variable from a job ? Is it even possible ?

Thanks

I have a partial solution, when I have already enabled Global Properties:

the following script works for me:

import jenkins.*

import jenkins.model.*

import hudson.*

import hudson.model.*

nodes = Jenkins.getInstance().getGlobalNodeProperties()

nodes.getAll(hudson.slaves.EnvironmentVariablesNodeProperty.class)

if ( nodes.size() != 1 ) {

  println("error: unexpected number of environment variable containers: "

          + nodes.size()

          + " expected: 1")

} else {

  envVars= nodes.get(0).getEnvVars()

  envVars.put("FOO", "foo")

  ...

  Jenkins.getInstance().save()

  println("okay")

}

I send this script to Jenkins with:

java -jar /tmp/jenkins-cli.jar -s http://localhost:8080/jenkins/ groovy /tmp/jenkins_global_vars.groovy

and the variables are set and persisted. What I haven't yet figured out, is how to enable the Global Properties in the first place

[Victor Volle]

Final solution:

instance = Jenkins.getInstance()
globalNodeProperties = instance.getGlobalNodeProperties()
envVarsNodePropertyList = globalNodeProperties.getAll(hudson.slaves.EnvironmentVariablesNodeProperty.class)

newEnvVarsNodeProperty = null
envVars = null

if ( envVarsNodePropertyList == null || envVarsNodePropertyList.size() == 0 ) {
  newEnvVarsNodeProperty = new hudson.slaves.EnvironmentVariablesNodeProperty();
  globalNodeProperties.add(newEnvVarsNodeProperty)
  envVars = newEnvVarsNodeProperty.getEnvVars()
} else {
  envVars = envVarsNodePropertyList.get(0).getEnvVars()

}

envVars.put("FOO", "foo")

instance.save()

Any idea how to make this delete all existing key pairs to ensure only the ones defined in this script  are the ones in Jenkins?

[Josh Branham]

Solved the problem, just add an envVars.clear() to the else statement 

[Rakesh Bachu]

Hi,

This script works fine when tested from 

So i want to do this with a job or a pipeline
how can i make a job or pipeline run this groovy script.

i'm getting random errors when I try to run this groovy script as part of a pipleline.

Thanks,

Rakesh

That code is a global configuration script which needs to be executed from the "Groovy console" of the Jenkins server.

It can't be used from a Jenkinsfile.

I just had to do this to fix it.

Jenkins instance = Jenkins.getInstance()
def globalNodeProperties = instance.getGlobalNodeProperties()
def envVarsNodePropertyList = globalNodeProperties.getAll(hudson.slaves.EnvironmentVariablesNodeProperty.class)
def newEnvVarsNodeProperty = null
def envVars = null

Hi Zilla, this doesn't work for me. I get:

java.io.NotSerializableException: hudson.slaves.EnvironmentVariablesNodeProperty

Any ideas?

Thanks,

Nick

[Nick Mellor]

Just to be clear: I had working code in Jenkins 2.19 that looked like this:

def appVersion(String app, incrementPatch = true) {

  assert app.toLowerCase() in ['appName'], "No such project implemented: '$app'"

  def version = [

          elms: env.VERSION_OVERRIDE,

          lacm: env.LACM_VERSION_OVERRIDE,

  ].get(app.toLowerCase())

  if (!version) {

    // auto-generate version number if no manual version given

    def nodes = Jenkins.instance.globalNodeProperties

    nodes.getAll(hudson.slaves.EnvironmentVariablesNodeProperty.class)

    if (nodes.size() != 1) {

      echo "Error: unexpected number of environment variable containers: ${nodes.size()} (expected 1)"

    } else {

      def envVars = nodes[0].envVars

      // last patch number used is maintained per major/minor version

      // stored in e.g. 'PATCH_VERSION_17.10' in Jenkins

      def majorMinorVersion = env.MONTHLY_RELEASE_VERSION

      def majorMinorPatchVar = "${app.toUpperCase()}_PATCH_VERSION_${majorMinorVersion}"

      String currentPatchVersion = envVars[majorMinorPatchVar]

      if (currentPatchVersion) {

        if (incrementPatch) {

          currentPatchVersion = (Integer.parseInt(currentPatchVersion) + 1) as String

        }

      } else {

        currentPatchVersion = '1'

      }

      // NB timestamp needs to be set statically by the pipeline

      // to maintain version parity between pipeline stages

      def timestamp = env.BUILD_TIMESTAMP

      version = "$majorMinorVersion.$currentPatchVersion-$timestamp"

      // create or update auto patch version for this major/minor build

      // this will create new variable in Jenkins if necessary

      envVars[majorMinorPatchVar] = currentPatchVersion

      Jenkins.instance.save()

    }

  }

  echo "Autogenerated ${app.toUpperCase()} version is '$version'"

  return version

}

Have had trouble since moving to Jenkins 2.31.

Hey guys, please hold the (no doubt excellent) advice to upgrade to the latest Jenkins: I'm at a large corporate that doesn't (can't, won't) move quickly on Jenkins version.

Thanks for any input,

Nick

[Nick Mellor]

the problem appears to be

hudson.slaves.EnvironmentVariablesNodeProperty.class

 passed as a parameter, but which can't be serialised.

[Cristian Banarescu]

Hey man! Your solution also worked for me! Thank you very much!
