Generate a json of required dependencies

[bsnisar]

Hello!

It is nice to introduce another task that instead of downloading a dependencies generate a list of dependencies. This is nice-to-have feature that I would like to use by my https://github.com/wix-incubator/bazelizer

Generate a file under target directory (or just print to stdout or by provided path) a list like:

{ "groupId": "<...>", "artifactId": "< .. >", "version": "<...>" }
{ "groupId": "<...>", "artifactId": "< .. >", "version": "<...>" }
{ "groupId": "<...>", "artifactId": "< .. >", "version": "<...>" }
....

Seems doable, I will look into it :)
