Unexpected `MissingRequirementError` with bloop console
See original GitHub issueHey, any idea what is going wrong here?
I can reproduce it with running:
sbt new scala/scala-seed.g8 and then bloop console root --verbose --version in this fresh project. Starting ammonite standalone works fine. Is that some misconfiguration of my machine or can you reproduce it?

From what I checked this might be an issue with missing jars on classpath, updating coursier should help as I did have the same problem with an older version, but it worked after updating.
Hmm… This might be it, I tested it all again and it doesn’t work again. I might have had JDK 8 by mistake since I was switching back and forth a lot. I checked what classpath is loaded and i all seems correct:
