This Go package was implemented by me to avoid having to use Mavan or
Gradle to resolve all the dependencies for Nix:
https://github.com/status-im/go-maven-resolver
The Go tool is essentially a slightly smarter and more efficient version
of the `get_urls.sh` script, which was mostly slow due to the `mvn
dependency:list` calls and slow HTTP requests.
This takes down the `make nix-update-gradle` target to under 2 minutes
on my machine.
