Java library for Minecraft launchers

Keep launcher code simple

Minified handles authentication, versions, assets, libraries, Java runtimes and mod loaders behind a clean, modular API.

ExampleJava

LaunchConfiguration config = new LaunchConfiguration.Builder()
    .assetsDirectory(Path.of("<your assets directory>"))
    .librariesDirectory(Path.of("<your libraries directory>"))
    .jarFile(Path.of("<path to your client.jar>"))
    .loader(new VanillaLoader("26.2"))
    .build();

Launcher.launchMinecraft(
    null, // Use the authentication guide to pass a user.
    config
);
