karaf-2.2.x/manual/src/main/webapp/developers-guide/features-maven-plugin-generate.conf

h2. Goal {{features:generate}}

The {{features:generate}} goal generates a features XML file for every bundle listed in the project's dependencies.  In order to satisfy the required imports in these bundles, the plugin will add bundles:
- bundles provided by Apache Karaf
- a explicit list of bundles
- bundles discovered in the POM's transitive dependencies

Afterwards, the generated file will be attached to the build as an additional build artifact (by default as {{group:artifact:version:xml:features}}).

h3. Example
The example below generates one feature that installs bundle {{mvn:org.apache:bundle1:1.0}} in a features XML file called {{target/features.xml}}.  It will find bundle in Apache Karaf ${project.version}, the transitive dependencies for this POM and the bundles listed in {{src/main/resources/bundles.properties}}.
