Is it possible to have pants force coursier to use a proxy? I can't seem to find a way to get past this error:

Exception in thread "main" java.lang.Exception: Error while getting <https://github.com/coursier/jvm-index/raw/master/index.json>: download error: Caught java.net.ConnectException (Connection timed out) while downloading <https://github.com/coursier/jvm-index/raw/master/index.json>

I've tried setting

coursier-url-template

but it only seems to work for the initial coursier binary download, and the advice here doesn't seem to work when coursier is being run by pants https://get-coursier.io/docs/other-proxy.

You can use this option to point coursier to custom repos: https://www.pantsbuild.org/docs/reference-coursier#repos

This value is already set to use our internal artifactory, so if it were looking for something there and not finding it, I assume the url in the error message would be our artifactory instead of github.

Ah, right, that index is where coursier looks for JVMs, not for maven packages.

Would it be reasonable to add the ability to pass this

jvm-index

argument to coursier from pants? https://get-coursier.io/docs/cli-java#jvm-index I think if I could have coursier use our own index file then I could do what I want to do without worrying about being blocked by our proxy.

Yes, I think that is necessary!

Great, yeah I would like to try. Should I make an issue first?

That would be great!
