First things first, you will need to have subversion installed on your local machine. You can get it from the Subversion site. Then create a directory in which to work. I've created the directory 'C:\iBatis' as an example.
Next step is to check out the latest code from the respository:
C:\iBatis> svn co http://svn.apache.org/repos/asf/ibatis/trunk
At this point you should have the entire directory structure starting with trunk in your working directory.
C:\iBatis> cd trunk\java\mapper\mapper2\build
You are now in the build directory. There are multiple scripts in this directory for building ibatis.
Now just run ant to do the build:
We choose here to build 'all', but you can run different targets by passing the name to the ant command. 'ant -p' will tell you targets that are available. For example, to run the 'clean' target, you would do this:
You get the picture
