Jenkins failed to start in linux

Question

go to run jenkins after doing an upgrade, and get the following:

start jenkins
start: Job failed to start

That\'s it...nothing shows up in jenk

Answer 1

I went to see the jenkins logs tail -f /var/log/jenkins/jenkins.log

In my case it didn't start because I used incompatible java version. Update and make sure it sees correct java (In my case it should have been opened using JRE 1.7. To check, please use java -version command) and all should work
