The Polarsys' hudson server can be accessed here.
Accessing a project
On hudson's home page, click on the line corresponding to your project. This should open your project's page, and the menu on the left hand side of the screen should be limited to "build status" and "modifications".
Configuring a project
At this point, it is necessary to login in order to configure your project. Warning : the hudson login is not your e-mail address, but your git login. Once you have logged in, you should have access to a few more options, such as "Workspace", "Launch" and "Configure". Click on "Configure". On the project configuration page, fill in the fields according to your project's attributes (names, permissions, JDK…)
Configuring the project SCM
The most important part on this page is "Source Code Management", in which you have to select "Git", and type in a repository URL matching the pattern file:///gitroot/geneauto/geneauto.git
I guess that for polychrony, it will be file:///gitroot/polychrony/polychrony.git etc...
Running the build
As long as you're logged in, you can launch a build manually, clicking on "Build now". Hudson can also be programmed so that builds are run whenever SCM repository reports a commit, or at fixed date, for instance at 2:00 a.m. every night.
