[feature request] fetch/resolve json report

Hi,

I am trying to integrate coursier with Pants build tool as a replacement for the existing ivy resolver. The goal is to have Pants to hand off the 3rdparty resolution/fetch job to coursier, then parse its result.

Currently the command line is great,

./coursier resolve -t (or -T) <artifacts ...>

but it is not machine friendly. To start with, essentially I would require, e.g. json representation of the tree, and potentially the reason for conflict resolution.

I am not very familiar with code base or Scala, so is it something an existing contributor can achieve relatively quickly? If not, can someone kindly point me to the relevant code?

Thanks, Yi

While https://github.com/coursier/coursier/commit/a4258f48ce7e9a3b432dc5227ab9cd2dfdc2471a did add a --json-output-file for the fetch command it did not add this for the resolve command - would it be trivial to also add it to resolve @wisechengyi ?

+1 to @Globegitter - this is really useful for Bazel as we can leverage Coursier’s resolution + Bazel’s highly cacheable download mechanism, as long as we have a way to parse the JSON output reliably from resolve.
