Jean-Baptiste Onofré commented on KARAF-6252:
---------------------------------------------
I'm not able to reproduce the issue. I tried to change the features path in
{{system}} folder, in {{.m2}} folder, even locally, without a
{{feature:repo-refresh}}, the change is not taken. I'm adding a test just to
avoid the NPE.

> Key: KARAF-6252
> URL: https://issues.apache.org/jira/browse/KARAF-6252
> Project: Karaf
> Issue Type: Bug
> Components: karaf
> Affects Versions: 4.2.5
> Reporter: Kamil
> Assignee: Jean-Baptiste Onofré
> Priority: Minor
> Fix For: 4.3.0, 4.2.6
>
>
> I had repository:
> {code:java}
> feature:repo-add mvn:io.my.company/features/1.0/xml/features
> {code}
> Then I changed folder name in the filesystem from "features" to
> "my.features".
> I tried to remove old repo from Karaf:
> {code:java}
> feature:repo-remove mvn:io.my.company/features/1.0/xml/features{code}
> but I've got:
> {code:java}
> No matching repository for mvn:io.my.company/features/1.0/xml/features
> {code}
> Then I've noticed that Karaf somehow tracked the change, and new repo
> appeared in repo-list:
> {code:java}
> feature:repo-list
> Repository | URL
> ----------------------------------+-----------------------------------------------
