Are you behind a proxy server? – Totality

You can change proxy settings under Window >> preferences >> General >> Network Connections – Cathode

I don't know if there is a proxy, how can i get this information? – Festus

If you are in a company, most probably you are behind a proxy. – Regurgitation

Answer 1

I am afraid, it is not proxy. Nor the antivirus. 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.

This didn't work for me, I'm behind a proxy and the certificate I see is coming from the proxy. So I need to import this certificate somewhere in eclipse i suppose. – Regurgitation

Surely, you have Eclipse newer than 4.3. I am afraid, now the reason could be different. Find your, recent way and publish it here as another answer. – Rhine

BTW, does your jvm has the certificate for the URL you are trying to reach? – Rhine

I have Eclipse Oxygen.1a (4.7.1a), I imported the certificate into cacerts of my JVM, and I set the -vm parameter in the eclipse.ini but no luck. Sorry if I commented at the wrong answer! – Regurgitation

The following reference is about different vm key, but the main thought remains the same - to change ini IS NOT ENOUGH! https://mcmap.net/q/424247/-java-lang-outofmemoryerror-permgen-space-closed – Rhine
