Add foreign Dependency to the Addon's POM fails

[bernhard o.]

Dear community

During the generation process of a addon (roo> addon create simple), following Error occured.

roo> osgi obr start --bundleSymbolicName com.example.testaddon                                                                                                                                         
Unsatisfied requirement(s):
---------------------------                                                                                                                                                                                    
   (&(package=org.slf4j)(version>=1.6.0))                                                                                                                                                                      
      TestAddon 

If i add the dependency of slf4j (slf4j api and slfj4j-log4j) to the pom always an unsatisfied requirement(s) exception is thrown, when i install the addon. This problem occurs even if i use the sfl4j version that is listed on the spring-repository, but Maven clean install works fine.

How can i solve this problem?
Adding the jar files with osgi install --url .m2/repository/org/slf4j/slf4j-api/1.6.1/slf4j-api-1.6.1.jar doesn't fix the problem.
Creating an osgi wrapper for these jar, only outsources the problem..

Kind regards & best wishes
