The error message is self-explanatory. Your DNS isn't working properly. services.gradle.org resolves correctly on my machine.

Does it have to get online in order to build a local project? – am6sigma Jan 17 '14 at 21:34
Yeah figured out how to set the proxy settings and that solved it. – am6sigma Jan 17 '14 at 22:34
@am6sigma It has to get online to download dependencies. I'm not sure what the Gradle syntax is, but Maven has a goal `dependency:go-offline` that makes sure to download everything it'll need. – chrylis -cautiouslyoptimistic- Jan 18 '14 at 03:06

Resolved the issue by setting my proxy settings.

Created a file called gradle.properties:

systemProp.http.proxyHost=my.prox.com
systemProp.http.proxyPort=12
