The following image shows the Swing GUI that can be used to inspect the incoming and outgoing dependencies of modules, packages and classes. You can move classes into other packages and see how the dependencies change. Dependency violations are marked in red.
To run the Swing GUI, call the class PackageFrame with the name of your jlayercheck.xml file:
java -cp jlayercheck.jar net.sf.jlayercheck.gui.PackageFrame my_jlayercheck.xml
