This repository contains a Maven Archetype that can be used to generate a Java 21 project.
Included example code will create a simple Java 21 Application:
Hello World!
Invoke command:
mvn archetype:generate -DarchetypeGroupId=com.dominikcebula.archetypes -DarchetypeArtifactId=java21-basic-archetype
Maven Archetype will ask about groupId, artifactId, version, package name and will generate a project skeleton.
Having the project generated, invoke:
mvn clean install
Build output will be stored under target folder.
You can execute generated jar using command:
java -cp target/generated-output-1.0-SNAPSHOT.jar com.dominikcebula.Application
