Evolving Scala
> If anyone care to share their experience with GraalVM's native-image, I'd be interested in hearing that.
The main issue is if you are using reflection, which needs metadata adding to describe it so the necessary metadata is included in the image. Some libraries already have it built in, and there are tools to help.
For building, https://github.com/sbt/sbt-assembly supports native Image.

Trouble with sbt-native-packager
sbt-assembly is still my go-to. So what I'd prefer is the combination of sbt-assembly (to build my .jar that I can just java -jar anytime I want) and sbt-jib (to construct my OCI image including my assembly .jar for deployment in some container orchestration environment).

SBT error when running package application: java.lang.RuntimeException: No main class detected.
You may also use sbt-assembly to produce an uber JAR that embeds the Scala stdlib together with your code, which means that now for running your program you only need a JRE like java -jar app-assembly.jar. This option is great because now if you start adding dependencies to your project those are also included in this massive JAR.
