When configuring Global Environment Variables in the "Manage Jenkins" view, the environment variables only seem to be accessible via the env global variable if it is inside the context of a node step.
I find this to be rather confusing, and would expect global variables defined in Jenkins to be visible in any scope within a Jenkinsfile.
See attached screenshot and the console output below for a reproduction case
node {
sh 'printenv | grep -i foo'
echo "env.FOO_PIPELINE is: ${env.FOO_PIPELINE}"
}
echo "Outside of a node: env.FOO_PIPELINE is: ${env.FOO_PIPELINE}"
Results in:
Started by user admin
[Pipeline] node
Running on master in /tmp/jenkins/workspace/printenv
[Pipeline] {
[Pipeline] sh
[printenv] Running shell script
+ printenv
+ grep -i foo
FOO_PIPELINE=beepboop
[Pipeline] echo
env.FOO_PIPELINE is: beepboop
[Pipeline] }
[Pipeline] // node
[Pipeline] echo
Outside of a node: env.FOO_PIPELINE is: null
[Pipeline] End of Pipeline
Finished: SUCCESS

[JENKINS-40455] Global environment variables are not accessible outside of node { }
Colin PUY
added a comment - Indeed this is so confusing !
We often use variables for private informations such as login/password/API key etc.... in our scripts that are committed in public github repositories.
These variables are set as global jenkins variable in our master node and we need to retrieve them in our pipeline scripts from master node.

If you run this without the env prefix you get a stack trace because the Groovy variable is not defined.
