I have this expression in Jenkins:

println User.current().toString()

In Jenkins script console it returns me the real user value which currently logged in. When I use this function in pipeline script, it returns me the value SYSTEM. any idea why? How I can't I get also here the real user who's logged in?

To answer your last question: 2 simple ways to get a user(name), who's really logged (and also who triggers a build) within the pipeline comes to my mind:

  • A) Use a plugin - Build user vars (I can recommend it as it is widely used and never failed me):

    Here's a code snippet from their official docs. It can be of course used also within declarative pipeline within some stage... This plugins sets several variables that you can use BUILD_USER (contains full name), BUILD_USER_ID (contain user ID) and more (see docs on the plugin page).

node {
  wrap([$class: 'BuildUser']) {
    def user = env.BUILD_USER_ID
  }
}

and/or example of a stage in a declarative pipeline:

stage('User ID') {
   steps {
      echo "User ID: ${env.BUILD_USER_ID}"
   }
}
  • B) Use jenkins core methods
def build = currentBuild.rawBuild
def cause = build.getCause(hudson.model.Cause.UserIdCause.class)
def name = cause.getUserName()
echo "User: " + name

Note: both approaches (A and B) should work directly within pipelines and within JSL (Jenkins shared library).

To answer also your question from the title: Using your exact method is a problematic and doesn't work for a pipeline script (see old discussions here with more details How to get Jenkins logged user or even official community ticket https://issues.jenkins.io/browse/JENKINS-14605.

  • Tnx for the info. So to summarize my case, there is no way to get current logged on user in pipeline script? – arielma Jan 16 '23 at 21:50
  • Maybe let's clarify what exactly do you mean and understand under a "logged user"? If a user X logs in and triggers a build, then both A) and B) approaches that I shown would display the ID of user X (or name, or first name etc) of the logged user who triggered it in a log. – David-kn Jan 16 '23 at 22:17
