This program is Java Swing Window and an embedded Groovy console where the user can run scripts and manipulate the window interactively.
The purpose of the project is to demonstrate how to create a sample scala project with simplified structure not following Maven boilerplate layout and making the assumptions that it is Scala-only, that there is no java source code and there is only one base package, aka namespace, which is omited.
In a standard Scala project the directory layout of the project would be like as shown in the schema below with lost of nested directories and the sub directories /com/org/apptest for the package com.org.apptest:
src/
main/
scala/
com/org/apptest/
Main.scala
UserInterface.scala
java/
This project simplifies the directory structure to:
src/
Main.scala
UserInterface.scala
This was tested sucessfully with jetBrains’s InteliJ Idea and Scala’s sbt tool.
To build the project go to its root directory and run:
$ sbt run

The created uber jar, namely myApplication-uber.jar can be run by just double clicking on it or running the command:
$ java -jar myApplication-uber.jar
