You might've forgot to add a dependency or it's written wrong. Also, you might be using incompatible versions of Java and Hibernate. More on this here: https://goo.gl/SjSlRA

This error means there's a class missing in your classpath during runtime. You need to create a jar with all your dependencies and have it in your classpath. Check Maven Assembly Plugin and how to add your dependencies to a jar: https://goo.gl/U2zr8k
