I am trying to run Apache POI project tests, but I get the following exception. I've seen this a few times already, but every time I get completely lost, what is JUnit trying to tell me?
Javadoc simply indicates “Threw when the filter removes all tests from the runner.”, But that does not mean the Ant filter, because it is thrown inside JUnit, so which filter might remove the tests here? How can I debug / fix the Ant file that gives me this message?
