Trouble with sbt-native-packager
2 projects | /r/scala | 7 Dec 2023

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).

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.

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:
