Embeded-Dependency did not show any error as you can place anything into the instructions. If the key-value pair is not known it will be simply inserted into the MANIFEST.MF as it is. Try writing Embed-Dependency, that should make it work.
A good example could be the following (how we created hibernate bundle for ourselves):
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<instructions>
<Bundle-SymbolicName>${project.artifactId}</Bundle-SymbolicName>
