This should run on any packaging that has classes. There are soooo many different types of packaging, such as war, ear, jbi, and many many more that I want to run testability-explorer on because they have code. This check should only not run if the packaging is a "pom" project and if there are not classes.

Fixed in http://code.google.com/p/testability-explorer/source/detail?r=349 Exclude only pom type projects. Now we get testability report for the maven testability plugin, for example.
