-------------------------------------
Summary: Allow to mark features as 'aggregate' features
Key: KARAF-1957
URL: https://issues.apache.org/jira/browse/KARAF-1957
Project: Karaf
Issue Type: New Feature
Components: karaf-feature
Affects Versions: 2.3.0, 2.2.9
Reporter: Raul Kripalani
When creating features descriptors, one would typically cross-reference
features in two cases:
* to express dependency => when feature A depends on feature B and feature C
* to express aggregation => when you want to provide a single 'entry point' to
install the entire application, i.e. feature A is a conglomerate of feature B
and feature C
If you're after the second use case, Karaf has a shortcoming: uninstalling
feature A won't automatically uninstall feature B and C.
This makes a lot of sense, so I wouldn't change this behaviour. However, it
would be nice to be able to mark a feature as an aggregate, so Karaf will know
in what cases it makes sense to uninstall referenced features.
A simplified example:
{code}
<feature name="A" aggregate="true">
<feature>B</feature>
<feature>C</feature>
</feature>
{code}
