We're happy to announce the release of Metals v1.6.8, which includes a few long-awaited features. It's also worth mentioning that we are working on a new iteration of Metals (v2), which will change some important things about how Metals works. You can already try out the latest milestone v2.0.0-M16.

For full details: https://github.com/scalameta/metals/milestone/87?closed=1

Metals is a language server for Scala that works with VS Code, Vim, Emacs, Zed, Helix and Sublime Text. Metals is developed at the Scala Center and VirtusLab with the help from contributors from the community.

TL;DR​

Check out https://scalameta.org/metals/, and give Metals a try!

Add scalafix diagnostics​

Thanks to warcholjakub it's now possible to see scalafix diagnostics in the editor from any linting rule. They are disabled by default, but you can enable them by setting metals.scalafixLintEnabled to true in your editor settings.

Use javac-based parser for Java source indexing​

For a long time, Metals used the QDox project to parse Java source code and provide some of the features when dealing with Java files and dependencies. These features could include providing javadocs or finding exact definition within a Java source file.

However, QDox is no longer well maintained and thanks to rkophs we now use the default javac parser to parse Java source code. This should make sure that we always support the latest Java syntax and will avoid any issues with incompatibilities between the different Java parsers.

Support for JUnit 5 tests​

JUnit 5 support has been a long-awaited feature for many users. It should finally be supported in all the build servers including Bloop using the Jupiter interface.

Also, thanks to Leon0402 it's now possible to discover individual JUnit 5 tests and run them.
