Answer 1

Found solution:

def build = currentBuild.rawBuild
def cause = build.getCause(hudson.model.Cause.UserIdCause.class)
def name = cause.getUserName()
echo "User: " + name

print name of user which run build.

If you encounter "Scripts not allowed" this also works;

Install the Build User Vars plugin found here

... then wrap your step, something like this:

steps {
    script {
        wrap([$class: 'BuildUser']) {

            var name = "${BUILD_USER}"
        }
    }
}
