#19480 Unable to run `fmt` on fresh repo `main` due to coursier incorrect architecture bug Issue created by sureshjoshi So, I thought this bug was just on one of my feature branches because I had done something whacky as of a month or two ago. Turns out it's happening to me on

main

on a completely freshly checked out repo as well! I mean, a few dozen questions here about why it seems to be just my machine and some other stuff, but there are no modifications to the repo - so I don't even think the JVM backend should be running... This comment links back to a long-running discussion on this topic.
