💰 Toss a coin... Cargo-like build system for Java

Geralt

Geralt is a simple Cargo-like build system for Java projects.

Hello World

You can initialize a new Geralt project by running:

$ geralt init

This will create a new Geralt project in the current directory. The structure of the project will look like this:

src/
  com/
    example/
      Main.java
geralt.toml

The Main.java file will contain the following code:

package com.example;

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

and the geralt.toml file will contain the following configuration:

[package]
name = "hello-world"
version = "0.1.0"

[dependencies]

You can build the project by running:

$ geralt run

This will compile the project and run the Main class.

You can also build the project without running it by running:

$ geralt build

This will compile the project and create a target directory with hello-world.jar fat jar file inside.

In order to add dependencies to your project, you can add them to the geralt.toml file under the [dependencies] section. For example, to add the org.apache.commons:commons-lang3:3.12.0 dependency, you can add the following line:

[dependencies]
"org.apache.commons:commons-lang3" = "3.12.0"

You can then run geralt build to download the dependency and build the project.

Installation

You can install Geralt by running:

MacOS with Homebrew:

brew install geralt

Linux via sdkman:

sdk install geralt
