remoting.jar file location on the jenkins controller

Question

I am using jenkins 2.319 version on my local CentOS 7.0 machine. When I am adding a new agent/node to my Jenkins server I can see that its copying the remoting.jar file from the controller to the slave node but i could not see the remoting.jar file on my controller server. Can anyone help me in locating this file on my controller node.

[03/08/22 01:20:42] [SSH] Starting agent process: cd "/var/jenkins" && java  -jar remoting.jar -workDir /var/jenkins -jar-cache /var/jenkins/remoting/jarCache

Answer 1

It appears to be bundled in the jenkins.war file.

On my jenkins installation there was a copy of the jenkins.war file already extracted at:
/var/lib/jenkins/%C/jenkins/war/
and the remoting jar can be found in:
/var/lib/jenkins/%C/jenkins/war/WEB-INF/lib/remoting-[version].jar

There was also the unextracted war file available at:
/usr/share/java/jenkins.war
which you can unzip into a directory and then find the remoting jar at:
WEB-INF/lib/remoting-[version].jar
