Simply check out this project as a submodule called "build" in your project
git submodule add ssh://git@github.com/pfumagalli/build.git build
git submodule update --init
Then bootstrap the project by running Ant:
ant -f build/bootstrap.xml
After a few question, the ivy.xml and build.xml files (plus all the support
files required to run Eclipse) will be generated in your current directory.
