>                 Key: KARAF-1600
>                 URL: https://issues.apache.org/jira/browse/KARAF-1600
>             Project: Karaf
>          Issue Type: Improvement
>    Affects Versions: 2.2.8
>            Reporter: Raul Kripalani
>            Assignee: Gert Vanthienen
>              Labels: features
>             Fix For: 2.2.9, 2.3.0, 3.0.0
>
>
> Currently, if one has multiple features depending on each other, where the same features or bundles are referenced twice or more, Karaf will attempt to resolve/install them as many times as they are traversed.
> E.g., pseudo-code:
> {code}
> feature a, contains:
>   feature camel-core
>   feature camel-spring
>   bundle 1
>   bundle 2
> feature b, contains:
>   feature camel-jetty
>   feature camel-http
>   bundle 3
>   bundle 4
> feature all, contains:
>   feature a
>   feature b
> {code}
> When one installs feature "all", Karaf will end up resolving/attempting to install camel-core multiple times as it hits it via transitive dependencies (via a, via camel-jetty, via camel-http, etc.).
> As a result, an unnecessary delay is experienced and this could be optimised to perform a two-phase feature installation procedure instead:
> - calculate the install plan (kind of like building an effective POM in Maven) and prune duplicates
> - perform the install plan
