sbt-jib VS scala-cli

There's also https://github.com/sbt-jib/sbt-jib/ if you're having trouble with sbt-native-packager

I have been using https://github.com/sbt-jib/sbt-jib for some time now, it makes building images very easy.

You should use sbt-jib. (You shouldn't use sbt-native-packager either, it doesn't work well in this regard: [1], [2].)

That has not much to do with the JVM. See Scala CLI[1] for instance, the developer experience is pretty similar to Cargo.

The thing is, with any non-trivial project, zero to hello world isn't a very useful metric. Gradle (and Maven, sbt, ...) do a lot more than Cargo, and their usage is primarily optimized for complex multi-modules projects.

Scala CLI v1.0.5 was released. https://github.com/VirtusLab/scala-cli/releases/tag/v1.0.5 This includes:

The new official Scala build tool / compiler front end (scala-cli) is amazing,

The thing that really struck me after years of python is how it lets you out dependencies directly in a comment on top of a script and it will download and run with them automatically, without poisoning any system settings. It's so simple!

sbt can indeed be a bit harsh for beginners. If your aim is not to build a big project, you might want to use scala-cli instead : no complex build script, only command line goodness to run, test, compile and package your code. Yes it supports dockerization. No need for a dockerfile.

Imo the tooling has to become way more user friendly. The Scala community has picked up on this and made Scala-CLI the official running tool for Scala. It's a great tool for single module projects and makes everything from adding dependencies to building fat jars very easy, also the runner comes as a native image. The reason I'm mentioning is because sometimes we forget how hard it can be as a beginner, especially when younger people are used to simpler CLIs from newer languages.

We even have a ticket for something similar right here. Feel free to upvote and/or comment on it.

Check out Scala CLI as it will very soon be the one true and sanctioned way to get started.
