Cant start osgi bundle because import cannot be allowed

Question

I made a small set of APIs and a set of services that the API should use.

In my maven pom.xml file, I added the dependecy function for my api package in the correct version as follows:

<dependency> <groupId>at.foobar.osgi.api</groupId> <artifactId>foobarapi</artifactId> <version>1.0</version> </dependency> 

I use the maven-bundle plugin to create packages, and because of this, I used mvn clean install to create the jar file. The manifesto looks like this (service):

 Manifest-Version: 1.0 Private-Package: at.foobar.osgi.producer Built-By: foobar Tool: Bnd-0.0.238 Bundle-Name: foobarproducer Created-By: Apache Maven Bundle Plugin Bundle-Version: 1.0 Build-Jdk: 1.6.0_26 Bnd-LastModified: 1332185439257 Bundle-ManifestVersion: 2 Bundle-Activator: at.foobar.osgi.producer.Activator Import-Package: at.foobar.osgi.api,org.osgi.framework;version="1.4" Bundle-SymbolicName: at.foobar.osgi.producer.foobarproducer 

which seems to be suitable for me. Import there, so everything should be fine.

Now I started the equinox and installed the API and distribution. Then I launch the API, which works fine. But when I want to start the producer service, I get this error:

 org.osgi.framework.BundleException: The bundle "at.foobar.osgi.producer.foobarproducer_1.0.0 [4]" could not be resolved. Reason: Missing Constraint: Import-Package: at.foobar.osgi.api; version="0.0.0" 

It seems that the structure cannot find api, but is it installed and running?

Make sure you export the API packages so that your service package can communicate with them.

In your maven-bundle plugin for the API package, you should have something like:

  <configuration> <instructions> <Import-Package> * </Import-Package> <Export-Package> at.foobar.osgi.api.* </Export-Package> </instructions> </configuration>
