I think this is what you want: http://mvnrepository.com/artifact/com.google.apis/google-api-services-analytics
In this case I just googled the artifact name ("google-api-services-analytics") but the structure of maven repositories tends to be very predictable. If you go one level up in the google code page you linked and check out maven-metadata.xml, that will tell you the group and artifact to look for in a repository.
