Conditional Features and capabilities
Hi,
I have two features implementing the same capability (and I can only install one of both - For example a capability "database" and two features, "derby" and "H2").
I have also a third feature, "web-user-interface", and I want that, when this feature and the capability defined earler are installed, then another set of bundles are automatically installed.
The "conditional" in the features.xml seems to allow this kind of behavior, but it looks like I can only specified a feature as a dependency, and not a capability.
How can I implement this scenario with Karaf 4.1?
Regards,Jérémie

Actually, requirements are supported in conditionals.
You need to prepend "req:" in front of the requirement, see the following
example:
