Command line used for generation

java -jar lib\swagger-codegen-cli-2.3.0-20171030.060918-211.jar generate -i https://api.my-clay.com/swagger/docs/v1 -l java -o .\

Steps to reproduce

In the genrated code the type declaration is missing in a lot of points, you have to define via hand final (String/Integer/Boolean) and in every api java file replace the line:

String[] localVarAuthNames = new String[] { };

with

String[] localVarAuthNames = new String[] { "BearerToken" };

Research direction

Run the listed swagger-codegen CLI command against the supplied Swagger URL and inspect the generated TagsApi.java, ApiClient.java, and JSON.java alongside the Gson stack trace. A useful result would first narrow the report to a reproducible failure involving generated types, response deserialization, paging, or authentication, with the expected behavior stated.
