Trouble getting user id variable on builds

[samuel....@madeiramadeira.com.br]

Hi, I need access to a Jenkins variable that defines the user who started the build.

It is essential for my usecase because i need to pass it to capistrano and newrelic, in order to log who did it.

I stumbled upon the Build User Vars Plugin[1], but it appears that it doesn't work, i can't seem to find the 'Set Jenkins user build variables' option.
I also found this[2] post explaining a different approach to use it on a pipeline script, which didn't work:

Started by user Samuel Henrique
[Pipeline] node
Running on master in /var/lib/jenkins/workspace/deploy-teste2
[Pipeline] {
[Pipeline] wrap
[Pipeline] // wrap
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline

It is really surprising how difficult it is to get a simple variable such as the user identification of who started the build on Jenkins.

Can anybody help me? I bet there's more people with this problem.

I'm using the last Jenkins release, 2.63

[samuel....@madeiramadeira.com.br]

Does anybody know where can i get help on this?

Getting the build user id is something someone already needed some time in the past for sure.

Hello, 

I am also getting same error. Anyone can help on this issue. Thanks

[Victor Martinez]

Can you confirm whether https://wiki.jenkins.io/display/JENKINS/Build+User+Vars+Plugin has been installed?

___ONLY_FOR_TRACKING_PURPOSES____

I just tried: as suggested in one of the URLs you posted, and it works like a charm:

pipeline {
  agent any

  stages {
    stage('build user') {
      steps {
        wrap([$class: 'BuildUser']) {
          sh 'echo "${BUILD_USER}"'
        }
      }
    }
  }
}
