Hi Asiri,
I see there's 10% of code duplication in the webdav module:
http://nemo.sonarsource.org/project/index/181898
This is the highest of all modules. Do you think you could have a look?
Second worst is REST with 5%
http://nemo.sonarsource.org/components/index/178319
In term of technical debt, WebDAV module is also high with 9.5% and
the highest is the XMLRPC module with 12.2%.
Thanks
