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.

Welcome to JAR Hell, Part 2: Deployment Strategies
Sbt-assembly defaults to silently concatenating configs. But even if it didn't, the configs wouldn't be in any particular order when resolving.

Building native images and compiling with GraalVM and sbt
With the sbt-assembly plugin you can create JAR-files with all of its dependencies (fat JARs). sbt assembly creates this target/scala-2.12/apply-at-vdb-assembly-0.1.0-SNAPSHOT.jar which has a size of around 42MB:

Scala.js AWS Lambda, using Scala 3
Take a look at sbt-native-image or sbt-native-packager for building the native image.

GraalVM native-image with Scala 3 reflection hell
The reason seems to be Scala 3's new encoding for lazy vals, where a reflective access to a variable called bitmap takes place. To demonstrate this, I took the http4s g8 template, set it up with Scala 3.1.0, added sbt native-image, started the nativeImageRunAgent and ran a single request against GET /joke. After stopping the server, the native-image run agent generated the reflective configs that are required for this path of execution. Comparing the generated Scala 2.13 with the Scala 3 configs, yields a bloated version for Scala 3 that contains these additional rules:

SBT error when running package application: java.lang.RuntimeException: No main class detected.
Assembly, however, has some disadvantages so you may also want to look into other alternatives like sbt-native-packager. You may even want to produce a binary using sbt-native-image (which uses GraalVM under the hood) so your users do not need to install anything at all, not even a JRE.
