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

I had to build one fat jar that will include all dependencies from the other jars that i wanted to use.
