I have been working on a ldd like program for Java. I put this program together using bcel for class file parsing, java-config to provide a list of installed packages and jars and a SQL db abstracted by sqlalchemy.

betelgeuse@pena ~/jarindex $ java -jar "/home/betelgeuse/java/JavaLDD/dist/JavaLDD.jar" -q /usr/share/ant-junit/lib/ant-junit.jar
ant-core
junit

Obviously this doesn't catch everything as you can load classes that provide an API dynamically but neither does ldd show dlopened shared libraries.

So soon ant-1.7.0 should be hitting the stable Gentoo machines. The biggest benefit here is that full ant with it's big dependency tree shouldn't be pulled in so often any more. Not all of the packages are migrated to splitted ant yet but the most important ones like Tomcat are. If you are interested in how this works I recommend you to take a look at the Ant guide we wrote:
