jdependency is small library that helps you analyze class level dependencies, clashes and missing classes.
Check the documentation on how to use it with javadocs and a source xref is also available.
The jars are available on maven central. The source releases you can get in the download section.
If feel adventures or want to help out feel free to get the latest code via git.
git clone git://github.com/tcurdt/jdependency.git
