Wiki Markup

This plugin introduces a game where users gets point on improving the builds.

The plugin is a simple proof of concept of the Build game that was created by Clint Shank. The idea behind the game is to decrease the number of times a build becomes broken. To win the game the developers have to commit code that is compiling and keep adding unit tests.


titleVersion requirements

Note that the plugin version 1.13+ requires Hudson 1.320 to work and the following plugin versions:

  • Checkstyle 23.01
  • Findbugs 34.0
  • PMD 23.01
  • Tasks 34.0
  • Warnings 23.0
  • Violations 0.5.4
  • analysis-core 1.0

The plugin is not activated for all jobs at start, each separate job has to activate the game. The game can also be de-activated in one job if some large merge activity is going to take place. To activate the game for a job, go to the job configuration page and check the , click "Add post-build action" and select "Continuous integration game box" from the list of available post-build actions.

Build score card

For each build the game calculates, according to the rules, the number of points that it is worth. Each user that is responsible for the build (ie comitters) receives the points.


  • PMD Plugin. Adding/removing a HIGH priority warning = -5/+5. Adding/removing a MEDIUM priority warning = -3/+3. Adding/removing a LOW priority warning = -1/+1.
  • Task Scanner Plugin. Adding/removing a HIGH priority task = -5/+5. Adding/removing a MEDIUM priority task = -3/+3. Adding/removing a LOW priority task = -1/+1
  • Violations Plugin. Adding/removing a violation = -1/+1. Adding/removing a duplication violation = +-5/-+5.
  • Findbugs Plugin. Adding/removing a HIGH priority findbugs warning = -5/+5. Adding/removing a MEDIUM priority findbugs warning = -3/+3. Adding/removing a LOW priority findbugs warning = -1/+1
  • Warnings Plugin. Adding/removing a compiler warning = -1/+1.

You are a maintainer of a plugin and would like to add rules to the game with data from your plugin. To do this you should declare the game plugin as an optional dependency to your plugin. To create rules implement the interface Rule, and group them together in a RuleSet. To add a RuleSet to the game, add it to the game's RuleBook.

Code Block



You would like to add rules to the game that are only valid for your organization and do not want to share them. To do this you should declare the game plugin as a mandatory dependency to your plugin. Then implement the Rule and add them to the RuleBook as in above point.
