Chuck Norris Jenkins Plugin
This plugin adds an absolutely delightful feature to Jenkins: depending if your build succeeds, fails, or is unstable, it will show a picture of Chuck Norris auto-adapting (that’s right, computer science it is!) to the build result!
Seeing that, already many thousands (yes, thousands!) of people have decided to take the plunge and install this plugin to finally see the light. Why not you?
