SwaCLIBasic Not doing anything but showing how picoCLI comes with batteries included
SwaCLIOptions A small demonstration on how to use (mutually exclusive) options and arguments
SwaCLISubCommands A small demonstration on how to use subcommands
SwaCLIProgrammatic An example that uses the programmatic API instead of the annotation system.
SwaCLISubCommandsTest An example on how to test commandline configurations

All examples are in Kotlin and provide the same rough capabilities (get some facts about characters or planets in Star Wars)

Running

$  ./gradlew customFatJar
$ java -cp build/libs/all-in-one-jar-1.0-SNAPSHOT.jar nl.lengrand.swacli.SwaCLI
# to keep color and paginate the results
$ java -Dpicocli.ansi=true -cp build/libs/all-in-one-jar-1.0-SNAPSHOT.jar nl.lengrand.swacli.SwaCLIOptions -p | less -R 
# to create the native image
$ cd build/libs;native-image --static -jar all-in-one-jar-1.0-SNAPSHOT.jar sw
# remove static if you're on Mac :)
$ cd build/libs;native-image -jar all-in-one-jar-1.0-SNAPSHOT.jar sw

Why

This is an example CLI that I created as illustration for my JFall 2020 talk
