Usually NoSuchMethodError happens when the application uses a different version of a library which is also used by the Metamap SDK. In the final application only 1 version of a library can exists.

You should use the same versions of the libraries that are used by Metamap SDK(of course if they exist in your project). The list of the libraries used by each version of MetaMap SDK can be found in the Maven POM File here
