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

h2. Goal {{features:add-features-to-repo}}

The {{features:add-features-to-repo}} goal adds all the required bundles for a given set of features into directory.  You can use this goal to create a {{/system}} directory for building your own Karaf-based distribution.

By default, the Karaf core features descriptors (standard and enterprise) are automatically included in the descriptors set.

h3. Example
The example below copies the bundles for the {{spring}} and {{war}} features defined in the Karaf features XML descriptor into the {{target/features-repo}} directory.
