Notice that the <Export-Package> instruction specifies that the bundle exports the Log Service package, even though that package is not contained in the bundle project. By declaring this, the plugin will copy the Log Service package into the resulting bundle JAR file. This is useful in the case, because now the bundle can resolve without having to download the entire compendium bundle. The resulting manifest for the Log Service bundle looks like this:
