Usage

Invoke command:

mvn archetype:generate -DarchetypeGroupId=com.dominikcebula.archetypes -DarchetypeArtifactId=java21-cli-pico-archetype

Maven Archetype will ask about groupId, artifactId, version, package name and will generate a project skeleton.

You can execute generated jar using command:

java -jar target/generated-output.jar
