    This exception normally means you either have to add the said class to your dependencies or you miswrote it. Look in the documentation of your library how to add it as a dependency.

    NoClassDefFoundError means java has failed to find a class you're trying to instantiate, look if you've added the class you're trying to instantiate to the dependencies.
