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.
