    A few things cause this exception: 1) Check if you have all jars and if they're in the correct path when running. 2) Your classpath might be broken, you can define it in the command line with "java -cp yourClassPath" or at your IDE if you're using one.

    If you're using Hibernate, this indicates you're missing FasterXML Classmate dependency, which you can add with the following: <groupId>com.fasterxml</groupId> <artifactId>classmate</artifactId> <version>1.0</version>
  4. Speed up your debug routine!

    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.
