Solution 2)

I had the same problem and neither helped. But your Eclipse simply can't reach a site because java 7 by default makes Eclpse to reach it throught the protocol IP6, that is not really supported by Eclipse, at least in versions till 4.3.

Go to cmd, use

setx _JAVA_OPTIONS -Djava.net.preferIPv4Stack=true

restart eclipse and it will work.
