SBT project for java executable jar

Question

What is the best way to set the target package for an SBT project to be an executable jar file?

It would need to bundle scala-library.jar and set the manifest for main-m

Answer 1

Use the assembly-sbt plugin (originally created by Coda Hale, now maintained by Eugene Yokota): https://github.com/sbt/sbt-assembly

Once you add this to your project it will build a so-called "fatjar" which is executable via java -jar projectName-assembly.jar. It will autodetect your main method -- if there is more than one in your source, you can explicitly set which one to use by setting mainclass, e.g.:

mainClass in assembly := Some("com.package.ClassNameWithMain")
