[SalesForce] Salesforce ANT migration tool login failure

We want to use ANT migration tool for our deployment. I have set it up but whenever I am trying to deploy the package, I get the following error:

BUILD FAILED
Failed to login: Failed to send request to https://login.salesforce.com/services/Soap/u/30.0

I checked my username, password and security token but that does not seem to be the issue. We have an office firewall.
How do i bypass this issue?
Any help will be hugely appreciated. Thanks.

You need to configure Ant proxy settings. Standard way is to set the environment variable ANT_OPTS="-Dhttp.proxyHost=proxy -Dhttp.proxyPort=8080"
