1. About java8-consoleapp-archetype

java8-consoleapp-archetype is a maven archetype for creating Java 8 console applications.

2. Features

• Generates complete directory structure (source code, tests, resources)
• Generates distribution script, so you can quickly package your application as .zip archive with all dependencies included
• Generates production-ready maven project with configured important plugins (compile, jar, source, javadoc, assembly)
• Generated project comes with most popular libraries:
  • JCommander for parsing command-line args
  • Guava for general purpose programming
  • slf4j and log4j2 for logging, preconfigured for both file and console logging
  • JUnit for unit testing
  • AssertJ or Hamcrest for assertions (you can choose during project generation)
  • Mockito or jmock for mocks (you can choose during project generation)

3. Installation

Before you can generate projects, you must install java8-consoleapp-archetype locally. If you use Windows, run install.bat. If you use GNU/Linux or Mac, run install.sh.

4. Usage

$ mvn archetype:generate -DarchetypeCatalog=local

You should see a list of locally installed archetypes similar to this one:

Choose archetype:
1: local -> org.thejavaguy.archetype:java8-consoleapp-archetype (Java8 console app archetype)
Choose a number or apply filter (format: [groupId:]artifactId, case sensitive contains): :

Simply choose a number in front of org.thejavaguy.archetype:java8-consoleapp-archetype (in this case, 1), answer questions about your groupId, artifactId etc. and your project will be generated in a directory one level below current one.

When your project is generated, go to project dir and type mvn package. As a result you’ll get .zip archive with a runnable JAR + resources + dependencies. Simply unpack it wherever you want and start it in a usual way (java -jar yourapp.jar).

5. Example

$ mvn archetype:generate -DarchetypeCatalog=local
