Scala 2.13.3 does not work with lsp-metals #33

Closed lightwave closed 4 years ago

lightwave commented 4 years ago

Describe the bug Scala 2.13.3 does not work with lsp-metals. Project with scalaVersion := "2.13.3" in build.sbt file fails the import step.

To Reproduce

  1. Install Courier & run cs setup. You should have scala 2.13.3 installed
  2. run sbt new scala/hello-world.g8 to create the hello world sample project
  3. In Emacs, open the hello-world-template directory you created above
  4. When asked to import the project, select import build
  5. After a few seconds, Metals Doctor would spit out errors recommending you to upgrade (downgrade) to 2.12.9 to make code navigation work. The exact error is Upgrade to Scala 2.12.9 and run 'Build import' to enable code navigation.

Expected behavior Expect code navigation to work for project with scala version 2.13.3

Looks like you use too old metals: https://scalameta.org/metals/blog/2020/07/01/lithium.html
