[error]  Error fetching artifacts:
https://github.com/virtuslab/scalafmt-native-image/releases/download/v3.8.3/scalafmt-aarch64-apple-darwin.gz: download error: Caught java.net.ConnectException (Operation timed out) while downloading https://github.com/virtuslab/scalafmt-native-image/releases/download/v3.8.3/scalafmt-aarch64-apple-darwin.gz

I lives in China, and there is a GFW, so the networking is not stable. I have a local 3.8.3 fmt which has been downloaded by scala-cli.
But everytime I run a scala-cli fmt , scala-cli will try to download the same 3.8.3, and then if the networking is bad, it will break the whole progress.

Describe the solution you'd like
Check if there is a local cache, if there is, skip the network checking, just run it.
if the local cache is broken, a user can run scala-cli fmt -f to run the whole progress, eg redownloading.

Describe alternatives you've considered
Run it from sbt shell

Additional context

We haven't investigated it, and v1.6.0 is long overdue anyway.
I'll try to get it on the roadmap once 1.6.0 is out.

I think it would be nice to add a try catch and set the connection connectTimeout?
