Installing plugin in Eclipse Problem

when i try to install the software in eclipse C/C++ edition, i enter the location: https://dl-ssl.google.com/android/eclipse/ in the ‘add repository’ dialog box and it warns that the location is a duplicate. same when i use just http:\…

not sure whats the problem. i have installed the android sdk in the eclipse classic edition, could this have done anything?

idk, thoughts?
