Hi, I tried installing bloop following MacOs instructions on installation guide but I keep getting the following error.

Thanks for reporting! This seems to be related to coursier/coursier#1989, however I am not sure why it even tries to download that index.json file since JDK should already be installed using brew.

As an alternative you could try using a bootstraped coursier jar to install Bloop with coursier as suggested in the comments.

Not sure what the root of this issue is, but ideally, the Bloop brew formula shouldn't use coursier. It should just download the Bloop binary itself. This is basically what it does currently, but indirectly via coursier. Using coursier here doesn't add or help for anything.

It's probably a leftover of when we installed bloop-jvm by default.
