In my eclipse Luna faced the same issue because of this URL https://sourceforge.net/projects/restfulplugin/files/site/

Preferences → General → Network Connections.

We had tons of issues here, namely with the proxy support. We ended-up using Pulse: http://www.poweredbypulse.com/

Pulse has built-in support for a few plugin, however, you can add third-party plugin and even local jar file quite easily.

Strangely it does not always use the built-in Eclipse feature, so sometimes when Eclipse become difficult ( like in our case for the proxy business ), you can work-around it with Pulse.

Answer 4

Use the following setting and you will be all set. Go to Window --> Preference --> General --> Network Connection --> select Direct from drop down

Answer 5

Couple of weeks ago I stumbled upon a Problem with Java and a MySQL-Connection. The Problem being that no Connection could be established. Anyway, the fix was to add -Djava.net.preferIPv4Stack=true to the command line.

I just added the same line to eclipse.ini and as it turns out, it also fixes this issue for me. The option name is pretty self-explainitory: It prefers the IPv4 stack over the IPv6 stack. So this solution may not be viable for everyone.
