To summarize: it seems like coursier knows that scribe is a dependency for the metals artifact, and the scribe jar includes this class, but when running the metals artifact the scribe class doesn't seem to be on the classpath.

I could not reproduce this bug:

$ coursier version
2.1.3
$ coursier launch org.scalameta:metals_2.13:0.11.12 -M scala.meta.metals.DownloadDependencies
2023.05.21 10:21:36 INFO  Downloading mdoc

It is hard to guess what's going wrong here. Could you share the output of coursier fetch org.scalameta:metals_2.13:0.11.12 | grep scribe ? Also what is your java -version ?
