External jar fetch from private S3 bucket

[gmendonca]

I'm trying to use bazel-deps to resolve maven dependencies on AWS S3 with coursier(see bazeltools/bazel-deps#275 and coursier/coursier#1488). If this works out, there's still something that I think it needs to be done here, I might be wrong, so bear with me.

Since bazel-deps puts the jars under //external:jar/, I'm assuming scala_maven_import_external needs to be able to recognise and download s3:// jar paths when building the project with such dependencies.

scala_maven_import_external underneath uses repository_ctx.download. This recently got authentication support (1.2.1?).
I think these are the bits you need to get in place.
Don't know a lot more though.
Good luck.

@gmendonca can we close this?

[gmendonca]

Yeah, sure. There's a FR on bazel already. Thanks!
