[jira] [Created] (FELIX-4478) Resolution failure
Guillaume Nodet created FELIX-4478:
--------------------------------------
Summary: Resolution failure
Key: FELIX-4478
URL: https://issues.apache.org/jira/browse/FELIX-4478
Project: Felix
Issue Type: Bug
Components: Resolver
Reporter: Guillaume Nodet
I'm having problems with fragments when using the resolver api. Those bundles are working fine with the framework resolver though, but I have currently no idea where the difference is.
The first problem is when I have a fragment which specifies packages which are imported and exported at the same time.
I end up with the following exception:
{code}
Error executing command: Uses constraint violation. Unable to resolve resource org.apache.karaf.shell.console [org.apache.karaf.shell.console/4.0.0.SNAPSHOT] because it exports package 'org.apache.karaf.shell.commands' and is also exposed to it from resource org.apache.karaf.shell.core [org.apache.karaf.shell.core/4.0.0.SNAPSHOT] via the following dependency chain:
org.apache.karaf.shell.console [org.apache.karaf.shell.console/4.0.0.SNAPSHOT]
import: (&(osgi.wiring.package=org.apache.karaf.shell.console.completer)(version>=4.0.0)(!(version>=5.0.0)))
|
export: osgi.wiring.package: org.apache.karaf.shell.console.completer; uses:=org.apache.karaf.shell.commands
export: osgi.wiring.package=org.apache.karaf.shell.commands
org.apache.karaf.shell.core [org.apache.karaf.shell.core/4.0.0.SNAPSHOT]
{code}
In the above org.apache.karaf.shell.console is fragment, org.apache.karaf.shell.core is its host and both org.apache.karaf.shell.commands and org.apache.karaf.shell.console.completer packages are imported/exported by the fragment.
Trying to work around this issue, I removed the imports on the fragment. But I have another exception with different bundles:
{code}
Error executing command: Uses constraint violation. Unable to resolve resource org.apache.karaf.jaas.blueprint.jasypt [org.apache.karaf.jaas.blueprint.jasypt/4.0.0.SNAPSHOT] because it is exposed to package 'org.apache.aries.blueprint' from resources org.apache.aries.blueprint.core [org.apache.aries.blueprint.core/1.4.0] and org.apache.aries.blueprint.core [org.apache.aries.blueprint.core/1.4.0] via two dependency chains.
Chain 1:
org.apache.karaf.jaas.blueprint.jasypt [org.apache.karaf.jaas.blueprint.jasypt/4.0.0.SNAPSHOT]
import: (&(osgi.wiring.package=org.apache.aries.blueprint)(version>=1.3.0)(!(version>=2.0.0)))
|
export: osgi.wiring.package: org.apache.aries.blueprint
org.apache.aries.blueprint.core [org.apache.aries.blueprint.core/1.4.0]
Chain 2:
org.apache.karaf.jaas.blueprint.jasypt [org.apache.karaf.jaas.blueprint.jasypt/4.0.0.SNAPSHOT]
import: (&(osgi.wiring.package=org.apache.aries.blueprint.ext)(version>=1.1.0)(!(version>=2.0.0)))
|
export: osgi.wiring.package: org.apache.aries.blueprint.ext; uses:=org.apache.aries.blueprint
export: osgi.wiring.package=org.apache.aries.blueprint
org.apache.aries.blueprint.core [org.apache.aries.blueprint.core/1.4.0]
{code}
In the above, the problem is that org.apache.aries.blueprint.core bundle has a fragment attached, and when debugging, I found out that the two chains are actually compatible, but one is using the bundle capability while the other is using the host wrapped capability (which are considered different).
Not really sure where to look at, especially as i have no problems when actually deploying the bundles.
