Is there a way to "install" a snapshot?

[ckipp01]

I sort of assumed I could do something like this:

cs install -r sonatype:snapshots metals:0.11.9+128-92db24b7-SNAPSHOT

But when I try this I get:

❯ cs install -r sonatype:snapshots metals:0.11.9+128-92db24b7-SNAPSHOT

Is this meant to work, or is there any way to achieve this?

It seems repositories passed to cs install aren't used to install the app for now. These are only used to fetch the channel data (that contains the app descriptors).

It seems this could be changed… The app descriptor can be changed in the AppInfo around here. Then the passed repositories should be taken into account.

So I failed to make it work and I need to focus on other things currently. My initial approach was in https://github.com/tgodzik/coursier/tree/add-repositories-to-install if anyone wants to continue.
