In Metals, this error manifests as a timeout exception during the BSP initialize handshake.
I expected Bloop to report an error in the cli like this instead
$ bloop compile frontend
[E] .bloop/frontend.json references missing file /Users/olafurpg/Library/Caches/Coursier/v1/https/repo1.maven.org/maven2/org/scala-lang/scala-library/2.10.7/scala-library-2.10.7.jar
In BSP, I expect Bloop to initialize but ignore build targets that reference missing jars. It could report errors via logMessage instead.
