changing work space directory doesn't do anything

[Zunayed Ali Morsalin]

Steps to reproduce

- Using a fresh instance of jenkins running inside a container from docker registry. 

- Created a multi branch project via blue ocean

- updated settings. Manage jenkins > configure system > home directory > advance button > change directory to ${JENKINS_HOME}/workspace/src/${ITEM_FULLNAME} > save

- restarted jenkins via jenkins_url/restart

- triggered a build but still creates the project in ${JENKINS_HOME}/workspace/${ITEM_FULLNAME}

Any ideas what I'm missing to get my builds into the custom path? Might be a bug?

my Jenkinsfile

node {

    checkout scm

    withEnv(["PATH=${env.path}:/var/jenkins_home/go_install/go/bin/",

             'GOPATH=/var/jenkins_home/workspace/',

             'GOROOT=/var/jenkins_home/go_install/go/']) {

        stage('Info') {

            sh 'printenv'

        }

        stage('Build') {

            sh 'ls'

            sh 'go get .'

            sh 'go build .'

            sh 'make setupenv'

            sh 'make'

        }

        stage('Test') {

            sh 'which docker'

            sh 'make test'

        }

    }

}

Thanks in advance!
