Hey Vishal,
Did you follow the instruction in the readme I linked to?
https://github.com/droolsjbpm/droolsjbpm-build-bootstrap/blob/master/README.md
How far did you get?
I followed it all through but built jbpm instead of guvnor, thus
<pre>
git clone https://github.com/droolsjbpm/jbpm.git
</pre>
Cloning a repo /is usually/ no prob behind a proxy - if U cannot access this url, you're of course at a dead end. I can mail it to you....
br,
Jens
