Hello,I'm running into an "Unresolved constraint in bundle" error, and hoping to get some insight into it. I'm using Felix system bundle 4.0.3. The application uses an OBR, with a thread that periodically checks for updates. Bundles are updated using Resolver. Here's the code which performs the updates (with null checks, etc. removed): repositoryAdmin.addRepository(new URL(repositoryUrl)); Resolver resolver = repositoryAdmin.resolver(); Resource resource = ... get the resource we want to update ... resolver.add(resource); if (resolver.resolve(Resolver.NO_OPTIONAL_RESOURCES)) { resolver.deploy(Resolver.NO_OPTIONAL_RESOURCES | Resolver.START); } The application is running in Felix with the following bundles: collector-api (0.2.2) - exports itself collector-engine (0.2.10) - imports collector-api >= 0.2.2 port-watcher (0.2.2) - imports collector-api >= 0.2.0 I updated the OBR in the following manner: - replaced collector-api 0.2.2 with collector-api 0.2.3 - replaced engine 0.2.10 with 0.2.11, which imports collector-api >= 0.2.3 When I resolve and deploy engine 0.2.11 with the above code, it throws the following error: ERROR 2013-10-02 16:52:58.235 (org.apache.felix.bundlerepository:?) - Resolver: Start error - com.rapid7.razor.collector.engine org.osgi.framework.BundleException: Unresolved constraint in bundle com.rapid7.razor.collector.engine [8]: Unable to resolve 8.29: missing requirement [8.29] osgi.wiring.package; (&(osgi.wiring.package=com.rapid7.razor.collector.api)(version>=0.2.3)(!(version>=1.0.0))) If I replicate the above scenario without the port-watcher bundle installed, then it works - the engine gets updated successfully. Any hints as to what is happening here?
Not sure. There is code in OBR that tries to update a bundle instead of deploying a second version. Perhaps it tries to update collector-api to 0.2.3 but determines that it breaks the port-watcher dependency if it does that so it fails. If that is the case, then that would be a bug since it shouldn't fail, it should deploy a second version of collector-api.
When you run your example without port-watcher is the existing version of collector-api updated to 0.2.3 or are there two versions of the bundle deployed?
