Unfortunately, I won't be of much help. The main artefact uses the Felix Maven plugin to generate this info in the MANIFEST.MF:
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<version>2.5.4</version>
<extensions>true</extensions>
<executions>
<execution>
<id>bundle-manifest</id>
<phase>process-classes</phase>
<goals>
<goal>manifest</goal>
</goals>
</execution>
</executions>
<configuration>
<supportedProjectTypes>
<supportedProjectType>jar</supportedProjectType>
</supportedProjectTypes>
<instructions>
<Bundle-SymbolicName>${project.artifactId}</Bundle-SymbolicName>
<Export-Package>*</Export-Package>
<Import-Package>
javax.persistence;resolution:=optional,
org.apache.log4j;resolution:=optional,
*
</Import-Package>
<_versionpolicy>[$(version;==;$(@)),$(version;+;$(@)))</_versionpolicy>
</instructions>
</configuration>
</plugin>
