Overview

Bushel provides utility classes for Ant Ivy that allow a developer to use a directory of OSGi bundles as a dependency repository. It does this through a custom metadata parser that converts a MANIFEST.MF file into a valid ivy.xml. The aim is to assist IDE-free OSGi development and continuous integration best practice.

Current limitations are that Import-Package and Export-Package parameters in the manifest file are ignored, however Require-Bundle is honoured.

Example

The Bushel example bundle is based on the Eclipse PDE/New Plug-in Project/OSGi Simple LogService Example.

It includes all the Ant and Ivy scripts required to compile and run the bundle, and can be used as a template for your own project.

To use the Ant script, you must provide the path to the Eclipse home dir (the parent dir of the plugins/ dir) using -Declipse.home=/path/to/eclipse. It provides the following targets:

• ant compile - Compile your bundle using Ivy to generate the classpath.
• ant bundle - Package your bundle jar ready for deployment.
• ant run - Run your bundle in equinox in console mode. Try ss, or diag 2, or help, and then finally close, to exit.

TODO

• Import-Package/Export-Package support.
• Examples with other OSGi containers (Felix, Knoplerfish etc).
• Eclipse Update site support.
