If you will read the error message, you'll see it's not related to your installed Java version nor to the Eclipse version you're using.
I've tried myself on Mac OS X 10.10.1 and Eclipse Kepler SR2. The installation from the Marketplace was successful. Note that the installed artifacts are the same whether you use Windows, Linux or Mac.
It was very slow, though, so it could be it something 'bad' happened during it.
This may also be due to either a network problem or temporary cache problem on the servers.
What you can do:
Wait and try again later,
Or download this Studio .zip file. Then, in Eclipse > Help > Install new software... > Add > Archive, and select the downloaded .zip file.
