#252

Describe the solution you've provided

Adds Automatic-Module-Name to Gradle's Jar Task configuration so it's properly picked up by Jigsaw.

This will still need a proper module-info.java in the future, exposing only the public code. Internal should not be exposed

Describe alternatives you've considered

N/A

UPDATE: This PR still does not solve it. Default Uber Jar generates a module-info.class with the following contents:

module com.google.gson {
  requires java.sql;
  requires jdk.unsupported;

  exports com.google.gson;
  exports com.google.gson.annotations;
  exports com.google.gson.reflect;
  exports com.google.gson.stream;
}

Closing this since it doesn't seem to be producing the desired result. Let's continue the discussion on the original issue #252.
