bnd is the Swiss army knife of OSGi, it is used for creating and working with OSGi bundles. Its primary goal is take the pain out of developing bundles. With OSGi you are forced to provide additional metadata in the JAR's manifest to verify the consistency of your "class path". This metadata must be closely aligned with the class files in the bundle and the policies that a company has about versioning. Maintaining this metdata is an error prone chore because many aspects are redundant.
