Having trouble starting Jenkins: “java.io.FileNotFoundException: /usr/share/java/jenkins/war/META-INF/MANIFEST.MF (No such file or directory)”

Question

I just downloaded the Jenkins WAR, version 1.651.1. I’m trying to set it up on my Amazon Linux box. I’m running Java 1.7. I moved the WAR into its own directory, /usr/sha

Answer 1

In my case, I had this problem because a user named "jenkins" was already created on my Mac.

After:

1. uninstalling the broken Jenkins with '/Library/Application Support/Jenkins/Uninstall.command',
2. removing the "jenkins" user,
3. and re-installing from https://jenkins.io/download

--> everything worked smoothly.
