Answer 1

You can use:

import jenkins.model.*
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()

Does anyone know how to access the Jenkins environment variables in groovy?

I can provide an example from a Jenkins job we use. The job is parameterized and provides the user with the ability to set many values, one of which is "InstallVersion" (default value is -1). Additionally, we set up an environment variable called "JENKINS_TRUNK_LABEL". I won't go into specifics about this job, but, here's how we refer to "JENKINS_TRUNK_LABEL" within a Groovy script.

if (InstallVersion == "-1")
{
  InstallVersion = "$JENKINS_TRUNK_LABEL"
}

Here is an example of some working code:

import jenkins.model.*
nodes = Jenkins.instance.globalNodeProperties
nodes.getAll(hudson.slaves.EnvironmentVariablesNodeProperty.class)
envVars = nodes[0].envVars
envVars['MY_GLOBAL_PROPERTY']

Note to the "hard core" moderator that deleted my previous answer: I have spent quite a few hours searching on the Internet before finding the right solution, you shouldn't delete posts without knowing what is it really talking about. I find such behavior rather discouraging :(

Answer 4

in "Execute Groovy script" you can access global (and build) variables by:

def env = System.getenv()
println(env['GLOBAL_VAR'])
