The code repository is hoested on sourceforge with the Version Control System [Mercurial].
How to start with Mercurial
Install Mercurial (also called "hg") as a package for your Operation System. You can download it from the [Mercurial Website]. You also need ssh for remote access to Sourceforge's Mercurial Server.
You can use mercurial from inside Eclipse with the [Mercurial Eclipse Plugin]. Out of Eclipse you can use [TortoiseHG] as an GUI to use Mercurial. The most powerful way to use Mercurial is by using the console. For this way you do not have to install anything but Mercurial itself. I will explain all needed steps for FreiBier development here with console commands.
You can also read the [Mercurial documentation].
Use this command to check out a first clone:
hg clone ssh://email@example.com/p/freibier/reports freibier-reports cd freibier-reports
...do some work on your files. Then look what has changed with:
Add a new file to the list of the managed files:
hg add reports/Kundenkopfdaten.jrxml
Commit your changes with a describing comment:
hg commit -m "Erste Version der Kopfdaten von M. Plueckhahn"
Push your own changes to Sourceforge's Mercurial Server:
Before you do some other work you should first pull the newest version from the server:
cd freibier-reports hg pull
If there is a conflict while pushing or pulling you have to merge. Read the docs and write it down here. :-)
