JBuild front-end. A modern Java build system that leverages Dartle to make building Java projects easy.

/// jb is meant to be used directly as a CLI tool to build Java projects.
/// However, it is possible to use it also as a Dart library.
///
/// This example shows how a [JBuildDartle] object can be created, which can
/// then be used to integrate it with a standard Dartle project.
///
/// As a configuration object is created from a const Map, this program can be
/// executed in any directory without the `jbuild.yaml` file, unlike the
/// "official" CLI utility. It looks for Java source code to compile in the
/// `src` directory. As the config object does not specify anything else,
/// the default options are used, which means a jar file is created with the
/// name of the working directory.
