Packaging as GraalVM native images ⚡
Scala CLI lets you package your applications as native executables using GraalVM native images.
As an example, let's package the following application as a native executable using GraalVM native image:
object Echo {
def main(args: Array[String]): Unit =
println(args.mkString(" "))
}
The following command packages this application as a native executable:
scala-cli --power package --native-image Echo.scala -o echo
# Run echo on macOS
./echo a b
# a b
You can pass custom options to GraalVM native image by passing them after --
, like
scala-cli --power package --native-image Echo.scala -o echo -- --no-fallback
