Jenkins running tomcat8 sudo: no tty present and no askpass program specified with NOPASSWD
There might be a workaround: As Barmar pointed out in a comment to the post "Use sudo without password INSIDE a script", it is possible to allow a dedicated script be executed by a sudoer. Assume you have a line
jenkins ALL=(ALL) NOPASSWD:/path/to/restart.shthis means that Jenkins can do sudo /path/to/restart.sh without a password.
If you now put your command service tomcat8 restart in restart.sh, a sudo /path/to/restart.sh should do the job.
Try turning off requiretty for the jenkins user. I would recommend using command aliases in your sudoers file as well.
