I have a jenkins instance running. To create this instance on a Fedora 23 machine, I installed jenkins (via dnf) and started it (via systemd). It is running and I can see it in my browser at http://localhost:8080.
I have been trying to follow the directions in https://wiki.jenkins-ci.org/display/JENKINS/Jenkins+CLI.
I download http://localhost:8080/jnlpJars/jenkins-cli.jar to my computer.
Then I try to run the program java -jar jenkins-cli.jar http://127.0.0.1 -s help
and I get no main manifest attribute, in jenkins-cli.jar
When I check jenkins-cli.jar, sure enough there is no Main-Class
entry in the manifest file.
What is the proper way to invoke the jenkins cli?
Addendum https://wiki.jenkins-ci.org/display/JENKINS/Starting+and+Accessing+Jenkins has a separate procedure for using the jenkins cli, but it does not explain where to obtain jenkins.jar.
