Missing Import-Package declaration in logback-classic causes problem with RollingFileAppender

                 Key: LBCLASSIC-131
                 URL: http://jira.qos.ch/browse/LBCLASSIC-131
             Project: logback-classic
          Issue Type: Bug
    Affects Versions: 0.9.15
         Environment: OSGi Service Platform Release 4 
            Reporter: Pavol Juhos
            Assignee: Logback dev list

In OSGi environment logback-core will correctly try to use the class-loader of logback-classic bundle to load classes of the selected Appenders. This however means that logback-classic needs to have visibility to the requested Appender classes. Since RollingFileAppender is located in a separate package "ch.qos.logback.core.rolling" and not explicitly referenced from logback-classic code, the respective Import-Package declaration will not be generated automatically by the BND tool (embedded in maven-bundle-plugin). 

In order to avoid ClassNotFound exceptions when trying to use RollingFileAppender the appropriate Import-Package declarations have to be added explicitly to the configuration of maven-bundle-plugin in logback-classic POM.

The current <Import-Package> settings in maven-bundle-plugin configuration:
