deadcode4j v1.4 released

deadcode4j v1.4 is out! It is available via Maven central, so it is conveniently available for your Maven project.

What's new?

Version 1.4 was all about customization, so that you can unleash the power of deadcode4j without waiting for the n^th feature to be added:

• Additionally to the annotations that can be configured, you can now define interfaces which, if implemented by a class, mark that code as being in use
• With annotations and interfaces, there's only one thing missing: superclasses - and they can be configured as well, thus marking subclasses as being in use
• As deadcode4j processes the whole reactor, there may be some example/testing modules which should not be considered - so now you can specify if a module shouldn't be part of the analysis

This should help you eliminate a good portion of the false positives being found by deadcode4j right now, helping you set up a configuration which recognizes dead code.
Nevertheless, v1.4 brings some more analysis features:

• Classes being listed in web.xml files as contextClass or contextInitializerClasses parameter for Spring's ContextLoader or FrameworkServlet are recognized as live code
• Hibernate Annotations processing:
• Classes referenced by the strategy parameter of a @GenericGenerator annotation are recognized as live code
• Classes referenced by the type parameter of a @Type annotation are recognized as live code
• Classes annotated with @TypeDef being referenced by a @Type annotation are recognized as live code
• package-info classes annotated with JAXB's @XmlSchema annotation are recognized as live code
• Classes being annotated with any of a bunch of JSF annotations are recognized as live code
• *Descriptor classes being generated by Castor are recognized as live code

How to use

It's so simple: go to the console, navigate to your Maven project, type
  mvn de.is24.mavenplugins:deadcode4j-maven-plugin:find ‑Dmaven.test.skip=true
and see what it finds.

Looking for reference projects & users

Currently I'm using the big legacy application of my employer as a reference project. But I'm slowly running out of false positives, so my feature list is shrinking. That's why I'd love to analyze some more projects to get more feedback. So, if you know of an (open source) candidate I can analyze or if you are using deadcode4j for yourself and want something added or you have some nice ideas, please comment!
