Guillaume Nodet updated FELIX-4478:
-----------------------------------
Summary: Resolution failure with fragments (was: Resolution failure)
> Resolution failure with fragments
> ---------------------------------
>
> 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.
