[jira] [Commented] (KARAF-1169) Support for hidden or dependent features....

["Guillaume Nodet (JIRA)" <ji...@apache.org>]

Guillaume Nodet commented on KARAF-1169:
----------------------------------------

I'll add a hidden="true" flag so that features won't appear in completers and feature:list output (and maybe add a flag on this command to actually display them).

> Some applications we have have blocks of common dependencies that are shared by multiple features.  We currently define them in a new feature, but that's not really what they are as it's not expected to be installed individually.  Right now, they appear in things like the features:list which can confuse users.   We can just put all the bundles in that feature into all the other features that need it, but that duplicates a lot of stuff and can create additional maintenance work. 
> There are a couple options that could be pursued:
> 1) Could just add a flag like dependency="true" or abstract="true" or hidden="true" to <feature> to mark the feature as something that shouldn't really be exposed to the user.
> 2) Create a new tag to express common blocks of bundles that can be depended on from a feature.  
> For example, CXF has a "cxf-saaj-impl" feature that installs the bundles needed for SAAJ to work.   That is then required by ws-security and jaxws and a few others.   It's not really something we would expect users to "features:install", but we also don't want to duplicate that setup in a bunch of other places.
