Subject [jira] [Created] (KARAF-2266) Warn and override when feature can not install files
Date Fri, 12 Apr 2013 07:31:15 GMT
Christian Schneider created KARAF-2266:

             Summary: Warn and override when feature can not install files
                 Key: KARAF-2266
                 URL: https://issues.apache.org/jira/browse/KARAF-2266
             Project: Karaf
          Issue Type: Improvement
          Components: karaf-feature
    Affects Versions: 3.0.0.RC1
            Reporter: Christian Schneider
             Fix For: 3.0.0

karaf can deploy files like config files during the installation of a feature. If the file
is already present then it is not overwritten.
I wonder if we should print a warning in this case. One use case for this is a new version
of a feature that adds a new needed property
to a config file. If the old feature was already present then the old config will be present
and the user may also have done changes.

So there might be cases where a feature works if it can install its default configs but does
not work when they are already present but invalid.
So we could write for each file that is already present:
"Warning: file <path> to be deployed is already present and will not be changed."

We could also provide an option in feature:install like -f that forces all files to be overwritten
if someone wants to make sure the feature installation should use the defaults.
