Comment by Anas Rabei on "What if I know the name of the dependency I want in my Gradle config, but I don't know it's group or version? How can I cheat by guess-matching?" | Hashnode
I think you don't need anything else. As far as I know, Gradle is only a build system, but in its heart it uses Maven Repositories (and probably others as well, but again, I'm not so experienced).
Thank you @lorthirk Turns out that group and version in the vector declaration are optional. I got this from the book "Gradle - Beyond the Basics" by Tim Berglund (on page 51).
