Library lookup allows choosing a non-existent version of the dependency

[danicheg]

For example, type 'cats' in the dependency search bar, and then choose version 2.1.1. The result is:

sbt.librarymanagement.ResolveException: Error downloading io.github.cquiroz:scalajavatime_sjs1_2.13:2.0.0

I think correct artefact is

https://search.maven.org/artifact/io.github.cquiroz/scala-java-time_sjs1_2.13/2.0.0/

[OlegYch]

@Sciss the scala-java-time item works i'm not sure what scala-java-time / scalajavatime is, please log the issue on scaladex side

[danwerner]

I ran into the same issue as the OP. Choosing simply "cats" as a library lead to the exact error in the original post, every time, no matter which versions of cats or Scala I selected.

I had to choose "cats / core" in order to make it work. According to the version matrix, the "cats / cats" artifact (which is resolved when you only specify "cats") has been deprecated since after version 0.9.0 and doesn't exist anymore for versions after this, in favor of "cats / core".

Is this a problem at Scaladex or Scastie that these non-existent artifacts are selectable?

[OlegYch]

@danwerner pretty sure it can only be fixed on scaladex side https://index.scala-lang.org/api/search?q=cats&target=JVM&scalaVersion=2.13 shouldn't list artifacts not available for 2.13

[danwerner]

@OlegYch It's not that the artifact is not available for Scala 2.13. It is not available in the newer Cats versions, e.g. 2.3.0 or 2.2.0. It is only available in Cats versions 0.9.0 and below.

[OlegYch]

@danwerner that's a separate problem

Related to #392 ?

[danicheg]

@vincenzobaz yep seems the same.
