Jenkins refuses to restart

Question

Following this answer, I have tried restarting a Jenkins instance using:

(jenkins_url)/safeRestart

and

(jenkins_url)/restar         


        

Answer 1

To manually restart jenkins :

1. Go to task manager and end all the java instances .
2. Close command prompt .
3. Open command prompt again, point the current directory where jenkins.war file is available.
4. And fire the command java -jar jenkins.war .

I happen to face this problem where restart was required to update jenkins version , I tried by url but faced the error - jenkins cannot restart itself as currently configured. Tried above mentioned steps and it worked.
