Fury Tutorial

The easiest way to start a new Java project with Fury is to clone an existing template. You can call your project anything you like, but for this tutorial we will call it sample. Start by running,

fury layer clone -l propensive/java-new -f sample
cd sample

This will set up a new Fury layer, already set up for a Java project, in the directory sample. We should start by renaming the default project:

fury project update -n `sample`

This quickstart project is set up to look for Java source files in the src/core directory, so let's create it with,

mkdir -p src/core

and create the file, src/core/Main.java with the following content:

class Main {
  public static void main(String[] args) {
    System.out.println("Hello World!");
  }
}

We can now compile this by running,

fury

This will not, however, run the application. To do that, we must first change it from a lib module to an app module, specifying its main method, like so,

fury module update -t app -M Main

Running fury again will now additionally run the code, printing,

Hello World!
