Plugin to get the plugins diff between two Jenkins servers

[alok joshi]

Hi folks,

I am wondering if there exists a plugin which takes a Jenkins URL as input, credentials as input and returns a list of extra set/list of plugins installed on this remote Jenkins, as compared to the Jenkins instance I am logged into.

It will have a similar UI experience with Job-import-plugin, but only returns the extra set of plugins installed on the source Jenkins instance. I don't want to add this feature into job-import-plugin because its a separate functionality altogether.

My org is making a platform change to host user's Jenkins instances on, and we would like such kind of functionality, so users are aware of the extra set of plugins they need to install on their new Jenkins instance.

Thanks,

Alok

Don't know about a plugin, but I would use jenkins-cli and a little shell-script
like this instead (untested, because written as I wrote this mail):

#!/bin/sh
JURL1=http://jenkins1.url
JURL2=http://jenkins2.url
curl -L $JURL1/jnlpJars/jenkins-cli.jar > jenkins1-cli.jar
java -jar jenkins1-cli.jar -s $JURL1 list-plugins | sort > plugins-jenkins1.lst
curl -L $JURL2/jnlpJars/jenkins-cli.jar > jenkins2-cli.jar
java -jar jenkins2-cli.jar -s $JURL2 list-plugins | sort > plugins-jenkins2.lst
diff -uw plugins-jenkins1.lst plugin-jenkins2.lst


Cheers
-Fritz
