Provides classes and interfaces to generate a JAR file. This package provides the interfaces and classes for exporting a set of resources to a JAR file via runnable. It offers hooks to extend the `JarPackageData` to load and store the `JarPackageData` and to write the JAR itself.

## Package Specification

The `JarPackageData` contains all necessary information to generate a JAR file. This class can be extended to provide additional data or to plug-in a custom `JarWriter`. The default runnable which creates the JAR can be replaced by implementing `IJarExportRunnable`. The same applies for the manifest provider (`IManifestProvider`) and the classes which save (`IJarDescriptionWriter`) and read (`IJarDescriptionReader`) the `JarPackageData`.
