This is a tool that helps you create a new project based on the LireJarp architecture pattern (https://github.com/witchpou/lirejarp). Setup of a new project consists of two things: renaming all elements according to your project needs (files, packages, war-file) and creating base functionality for new domain objects. So project builder is a tool that collects in a GUI some data for your new project.

Build project with mvn package and if successful run java -jar target/projectbuilder.jar
