Either change the following line in client-spec.mustache.
'''
{{paramName}} : in {{^isFile}}{{^isString}}{{^isPrimitiveType}}{{^isContainer}}{{package}}.Models.{{/isContainer}}{{/isPrimitiveType}}{{/isString}}{{/isFile}}{{dataType}}{{#hasMore}};{{/hasMore}}{{/allParams}}{{#returnType}};
'''
into
'''
{{paramName}} : in {{^isFile}}{{^isString}}{{^isPrimitiveType}}{{^isContainer}}{{/isContainer}}{{/isPrimitiveType}}{{/isString}}{{/isFile}}{{dataType}}{{#hasMore}};{{/hasMore}}{{/allParams}}{{#returnType}};
'''

or change what's inside '''{{dataType]]'''.

Do something similar with file client-body.mustache,
