Jenkins : Pry Plugin

Plugin Information

View pry on the plugin site for more information.

This plugin lets you remotely inspect/alter running Jenkins instance through pry. Think of it as the Ruby version of the Groovy shell console


This plugin adds the "pry" command to Jenkins CLI, which allows you to connect to Jenkins from a remote machine and execute a pry session remotely. Type "help" in the prompt to get the list of available pry commands. A sample session below:

$ java -jar cli.jar -s http://localhost:8080/ pry
[1] pry(Launcher)> { |j| j.display_name }
=> ["foo"]

Note that the Ruby code is executed on the server, and the CLI client is used merely to display output and read input. So code like puts "Hello" will end up printing to the server's stdout, not to your CLI. To show something to CLI stdout, use "output" object, like output.puts "Hello".

The pry session exposes 3 variables:




the Jenkins instance, the root of the object tree


IO object connected to the CLI client's stdin


IO object connected to the CLI client's stdout

The plugin preserves the readline support in pry, so auto-completion, command history, and all the other goodies in pry will work as expected.
