No Test Explorer or Run/Debug Code Lens on Cross Project

[valencik]

Describe the bug

1. Run sbt new typelevel/typelevel.g8 and accept all the defaults.
2. Open the newly created project in VSCode with Metals, note no tests found:
   

If we change the build in build.sbt from

lazy val core = crossProject(JVMPlatform, JSPlatform)
  .crossType(CrossType.Pure)
  .in(file("core"))
  //...

to

lazy val core = project
  .in(file("core"))

and let Metals reimport/reindex the build, we get tests and code lens:

Expected behavior

Test explorer and Code lens should show up and work as normal with crosscompiled projects

Operating system

Linux

Editor/Extension

VS Code

Version of Metals

v0.11.9

This seems to be on bloop. Metals sends buildTarget/scalaTestClasses to collect information about tests but bloop just doesn't reply. That also means that if you had some tests discovered before e.g. by sbt it won't get updated.

Looks like part of the problem was scalacenter/bloop#2104 and at least the compilation would work. Can be tested with Bloop 1.5.8-4-b8701857-SNAPSHOT <- main problem was that typelevel projects seem to have more options, which caused the bug in Bloop to show.

And it seems the other issue is scalacenter/bloop#2107

The node_modules directory was missing and I am not sure why and how it's setup in the project, since we need node_modules for sure.

Fixed on bloop side.
