Solution: I tried almost everything found on net for almost 2 days, that did not work. Initially i was trying to build with maven 3.x version, seeing
this error, i switched to maven2.x, but still same error. Initially i was using jdk1.7, then i downgraded to jdk 1.6 but that also did not solve the problem.
My OS was win7 64 bit and i heard somewhere about java 32 bit and 64 bit. I downloaded both 32 and 64 bit java, modified all environment variables but still
same issue persisted. Somewhere i read about Windows Firewall enabling/disabling. I enabled/disabled Firewall, allowed java/http through allowed programs,
but that also did not fix the issue. I use a wireless router to route the network connection got from my ISP. I even removed that connection and tried to
use the IP directly by my system (since the router was giving me local IP such as 192.168.1.2 and i though that might be problem), but still same issue :(.
At last what fixed it, is interesting: I had purchased a new system which had Intel motherboard. There was in-built antivirus and Firewall installed with it.
When i disabled 'Personal Firewall' from that ESET security options. Then maven started downloading everything and built successfully.
Interestingly, this fixed other couple of issues: such as running IE 64 bit version and downloading files using torrent.

I had to stop my vpn connection to work to stop this problem. Strange, I thought only my connection to my work url went through the vpn.
Thanks . This was a life saver . I would have never thought of this .
exactly the same as the first Anon. I had to cull my VPN connection also, then everything was perfect.
Try adding this to your environment variables.
MAVEN_OPTS=-Djava.net.preferIPv4Stack=true
Apparently it is a known bug in JDK 1.7. This fixed it for me.
Thanks for the MAVEN_OPTS=-Djava.net.preferIPv4Stack=true suggestion. Worked for me on Win7 over a VPN.
Fantastic! MAVEN_OPTS=-Djava.net.preferIPv4Stack=true fixed my Win7/VPN issue as well. Now I don't need to close down the VPN connection when maven needs to pull down new dependencies.
Thanks for the MAVEN_OPTS=-Djava.net.preferIPv4Stack=true suggestion. Worked for me on Win7 over a VPN, as well.
Thank you very much!I have more than 4 hours searching for this solution
MAVEN_OPTS fix did NOT work for me. Has anyone stumbled upon any other solutions. I cannot disconnect from VPN because the maven repository is on the network...
-Djava.net.preferIPv4Stack=true
Worked beautifully thanks.
Was pulling my hair out and cursing my company's VPN policy.
