Hi, You may want to check out the discussion on the related closed issue <https://github.com/googleads/googleads-java-lib/issues/19> for the Java client library. That NullPointerException means that your request is failing, probably due to missing parameters in your ~/ads.properties file.
Are you using the latest version of the client library? I ask because the issue was fixed recently by the release of google-oauth-client <http://mvnrepository.com/artifact/com.google.oauth-client/google-oauth-client> 19.0.
