How to get the current session user in Jenkins on a Groovy parameter

Question

I need get the current log in user in Jenkins, I am using a Groovy parameter but I don't know how to get that,

Thanks,

Answer 1

You should be able to call:

import hudson.model.User
...
User.current()

From a groovy script to get the current user :-)

Answer 2

def user = build.causes[0].userId

Answer 3

import hudson.model.*

def job = Jenkins.getInstance().getItemByFullName(env.JOB_BASE_NAME, Job.class)
def build = job.getBuildByNumber(env.BUILD_ID as int)
def userId = build.getCause(Cause.UserIdCause).getUserId()
def user = User.current()
println(user);
println(userId);
