sbt VS Metals

After spending one day or two reading documents and many frustrated attempts to fix the issue, I ended up arriving at this Github - Spurious recompilation in multi-project build This was not the fix itself, however, gave me light by the end of the tunnel to understand the problem was indeed with the multi project setup.

NOTE: I won’t mention SBT and Leiningen here because, with all due respect, they are niche build tools. I also won’t discuss Kobalt for the same reason (besides, it’s no longer actively maintained). Additionally, I won’t touch upon Bazel and Buck in this context, mainly because I’m not very familiar with them. If you have insights or comments about these tools, please feel free to share them in the comments 👇

Sbt has the primitives that would allow that, but this would change the semantics of the test task. See also testQuick and https://github.com/sbt/sbt/issues/6292

If I use IntelliJ then apparently sbtn is not supported and they don't bother with Scala-CLI or Coursier.

Version 1.3.13 has a size of 1.17 MB in zip

See scala-xml 2.x mega tracker on plugin ecosystem conflicts.

This is under discussion at https://github.com/sbt/sbt/issues/6997

See https://github.com/playframework/playframework/issues/10572 and https://github.com/sbt/sbt/issues/6235 for more details and context.

BTW, if you're curious, it appears OP is using this: https://github.com/sbt/sbt/releases/tag/v1.6.2 Pretty sure one of the executables is doing ANSI colours.

If you see the progression of documentation changes over the years pushing people towards multi-project style, and issues like https://github.com/sbt/sbt/issues/6217, hopefully you'd see that I've really tried to encourage people to use multi-project style from the get go.

You might want to look at Scala, they have proper LSP support with metals which means you can write your code in vscode, neovim, emacs, or even fleet (the new jetbrains text editor).

Please write in the comments if you know of any language servers I should test it with. Currently I tested only metals and rust-analyzer.

If you are using nvim-lspconfig you can pass the settings as a Lua table to the setup function. For example, here are may metals settings:

Bazel support in Metals. I didn't spend all that time figuring out and adjusting Emacs/Spacemacs and making my workflow (almost) mouse-free just to scrap my config and switch to IDEA's rodent infested ways.

There is one small issue involving code completion returning inappropriate completions in some cases; https://github.com/scalameta/metals/pull/4414 will fix it, once it's included in a release. Perhaps that's the PR you saw?

It is, by quite a bit.

While the "Scala IDE" project is dead for all practical purposes, IntelliJ IDEA's Scala plugin is actually pretty amazing. There's also a VisualStudio plugin that does pretty much the same and is advancing by leaps and bounds. There are also interconnecting projects that provide i.e. language server or build server that are reused by other projects. It's pretty modular. Metals (https://scalameta.org/metals/) is amazing.

In general the language has become a wee bit faster to build, there was good progress with build times during the 2.12/2.13 cycles.

With Scala3 the language got a bit simpler; concepts that were implemented explicitly using (hehe) implicits got their own keywords and a lot of the opinionated boilercode that cause a lot of debates is now generated during complication and hidden. A lot of "standardization" has occurred.

IntelliJ has its own BSP. The other one is Metals. You can use it with many IDEs (vim, emacs, vscode, atom,...). Use it with emacs if you're comfortable with it.
