Build Errors while setting up sagan

[fortm]

I am trying to understand the sagan source but have not been able to get it up and running since yesterday on 2 OS.

First one I tried was a proxy Windows 7 OS where it could not move past an error
gradlew.bat -Dhttp.proxyHost=xyz.com -Dhttp.proxyPort=8080

Running build gave following error and it fails in npmInstall stage :

bower curl#~0.8              ENOTFOUND Request to https://bower.herokuapp.com/packages/curl failed: getaddrinfo ENOTFOUND

If you're behind an HTTP proxy, you probably need to configure npm with your proxy details:

npm config set proxy http://xyz.com:8080
npm config set https-proxy http://xyz.com:8080

As for the second error, did you perform the build from a checked out repo or just a tarball?
It seems that our git plugin can't retrieve the current commit information.
