--------------------------------------
Summary: Provide a way to override bundles at feature installation
time
Key: KARAF-2752
URL: https://issues.apache.org/jira/browse/KARAF-2752
Project: Karaf
Issue Type: Bug
Components: karaf-feature
Reporter: Guillaume Nodet
Assignee: Guillaume Nodet
Fix For: 3.1.0
This would be very beneficial when trying to provide some kind of "patched"
distributions of Karaf and based applications.
When installing features, if you want to modify a bundle, the only way is to
release a new feature file which can be problematic, especially when the target
bundle is a transitive dependency, because you then need to release multiple
features descriptors in various projects.
The idea is to provide a simple file in etc/overrides.properties which will
contain a list of bundle urls to consider as replacements when installing
features. Before installation, bundles will be scanned for matching overrides.
Matching is done so that the target and override bundles must have the same
symbolic name and the target bundle version must has the same major and minor
version than the override bundle. This version range can be specified manually
using something like:
{code}
url;range="[2,3)"
{code}
in which case, any target bundle matching the version range and the symbolic
name will be overriden.
