I am using Rtc eclipse client 4.2x and Rtc server sdk 6. 0.5 to build the Plugin project. While building the site. Xml file, I am getting error inside eclipse error log.

Error - could not create feature file and problem in parsing  the feature file. The feature file which is creating issue, is present inside Rtc server sdk's feature folder(org. eclipse. equinox.sdk 3.10.2../feature. xml). I tried to build Plugins using eclipse Luna, but there also, I am getting same error. I tried with fresh download also, multiple times but it doesn't help. I have extracted the software by 7zip.some one please guide me to solve this issue, as it is urgent.
