------------------------------------------
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.
