Yuuka

Yuuka is a lightweight build tool for compiling your Java projects from the CLI in a fast and simple way. Yuuka implements the Java compiler and JAR management tool to build, manage and clean up your projects in a platform-agnostic way. Optionally, you can configure your projects declaratively from a build file too.

Requirements

• Java 11 or newer

Yuuka currently requires that you have Java installed in your system (in your $PATH) to execute the Java compiler, JAR packager and Java runtime.

Download and run

Download the latest release and run it with java -jar yuuka.jar.

How to use

With Yuuka, your projects should have a simple file structure such as:

/build        # Mandatory, to store the compiled project
/lib          # Optional, to store library JARs
/src          # Mandatory, to store source code
/test         # Optional, for writing and running tests
/build.yuuka  # Optional, for configuring your project
/libs.yuuka   # Optional, for fetching remote libraries

To start a new project, you can run yuuka init to create a new project structure.

To build your project and run it locally, you can run yuuka build and yuuka run. If you want to make an executable JAR, you can run yuuka package.

There are multiple CLI arguments that let you customize the build process, such as specifying the JAR name and main class (instead of guessing), setting verbose or silent terminal output, setting the target Java release for your program, etc.

For the automatic main class detection to work, it's recommended that your main file is called "main.java", otherwise you can define the main class manually either from the CLI or in build.yuuka.

Compile from source

Using Yuuka

yuuka package

If you don't have Yuuka installed in your system, run instead:

java -jar yuuka.jar package

Using Bash

mkdir build
bash build.sh

In a Unix-like shell

mkdir build
javac src/yuuka/*.java src/yuuka/*/*.java -d build
cd build
jar cfe yuuka.jar yuuka/main yuuka/*.class yuuka/*/*.class
cd ..
