Hello,
we have grouped some of our bundles with their dependencies into a
custom feature.
Now if we install this feature in an empty karaf (3.0.0), everything
works as expected.
But in case we want to update that feature (feature:uninstall/
feature:install), this fails with the following error:
Refreshing bundles org.springframework.web.servlet (124),
org.springframework.web (123)
Error executing command: Could not start bundle
mvn:org.springframework.hateoas/spring-hateoas/0.8.0.RELEASE in feature(s)
<customFeature>-1.0.0-SNAPSHOT: Uses constraint violation. Unable to resolve
bundle revision org.springframework.hateoas [221.0] because it is exposed to
package 'com.fasterxml.jackson.databind' from bundle revisions
com.fasterxml.jackson.core.jackson-databind [218.0] and
com.fasterxml.jackson.core.jackson-databind [201.0] via two dependency chains.
Chain 1:
org.springframework.hateoas [221.0]

(&(osgi.wiring.package=com.fasterxml.jackson.databind)(version>=2.2.0)(!(version>=3.0.0)))
|

com.fasterxml.jackson.core.jackson-databind [218.0]
Chain 2:

|
export: osgi.wiring.package=org.springframework.http.converter.json;
uses:=com.fasterxml.jackson.databind
org.springframework.web [123.0]
import:

|
export: osgi.wiring.package=com.fasterxml.jackson.databind
com.fasterxml.jackson.core.jackson-databind [201.0]
I also tried to install/ reinstall the feature with the -v switch, to
see what bundles are installed. The list is just the same, only that the
messages are different (which are "Found installed bundle" in case the
install command is run in the empty karaf, and "Installing bundle" in
case the feature is reinstalled - for me those LOG messages sound like
they are interchanged).
As I can't see any differences: why is karaf behaving this way? Why does
our feature install in an empty karaf, but we are not able to update it
(even if it is exactly the same feature)?
Here is our feature.xml:
<features name="customFeature-${project.version}"
xmlns="http://karaf.apache.org/xmlns/features/v1.0.0";>
<feature name="customFeature" version="${project.version}"
resolver="(obr)" description="...">
