Jenkins ci-game plugin

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.

Usage

Configuration

Version requirements

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

  • Checkstyle 3.1
  • Findbugs 4.0
  • PMD 3.1
  • Tasks 4.0
  • Warnings 3.0
  • 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, click "Add post-build action" and select "Continuous integration game" 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.

Clicking on the link shows what rules that were involved in the point calculation.

Leader board

To see who is winning the build game, there is a leader board that is shown on the front page.

  • +1 points for each new test that passes Rules that depend on other plugins:

Adding rules to the game

Currently there are three ways to add rules to the game.

Patch

Send me a patch for the rule implementation, and I can include it in the main game plugin.

Including rules in another plugin

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.

hudson.plugins.cigame.PluginImpl.GAME_PUBLISHER_DESCRIPTOR.getRuleBook().addRuleSet(pluginruleset);

If there are already rules for your plugin in the game plugin, let me know so they can be removed from the plugin.

Include rules in a third plugin

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.
