> -----------------------------------------------------------------
>                 Key: KARAF-5123
>                 URL: https://issues.apache.org/jira/browse/KARAF-5123
>             Project: Karaf
>          Issue Type: Bug
>          Components: karaf-feature
>    Affects Versions: 4.1.1
>            Reporter: Christian Schneider
>            Assignee: Guillaume Nodet
>             Fix For: 4.2.0, 4.1.2
> To reproduce:
>     feature:repo-add activemq 5.14.5
>     feature:install activemq-client
>     feature:repo-remove activemq-5.14.5
> After this step karaf is in an invalid state but no error / warning is shown
>     feature:install jdbc
>     Error executing command: Unable to resolve root: missing requirement [root] osgi.identity;
osgi.identity=activemq-client; type=karaf.feature; version="[5.14.5,5.14.5]"; filter:="(&(osgi.identity=activemq-client)(type=karaf.feature)(version>=5.14.5)(version<=5.14.5))"
> When installing any other feature karaf complains about the feature activemq-client as
it knowns it should be installed but does not find the repo anymore.
> The workaround is to remove all features that are now not available anymore in one step.
Removing individually does not work if there are more than one feature missing as feature:uninstall
is only executed if it leaves karaf in a valid state.
> I propose we these things:
> - At least we need to provide a warning when executing feature:repo-remove and list all
features that are now unavailable.
> - Even better would be to refuse to remove the repo when some of its features are still
needed. Eventually we want an override like -f to force removal.
