</project>

When i run maven build ,it created 2 jars file ,one with dependencies and one without

But in the one with dependencies ,the MANIFEST.MF not include OSGi configuration like :

Manifest-Version: 1.0
Bnd-LastModified: 1392281245886
Build-Jdk: 1.6.0_45
Built-By: myname
Bundle-Activator: activator.Activator
Bundle-ManifestVersion: 2
Bundle-Name: test
Bundle-SymbolicName: org.wiperdog.logstat
Bundle-Version: 1.0.0
Created-By: Apache Maven Bundle Plugin
Export-Package: activator;uses:="org.osgi.framework";version="1.0.0",ser
 vice;version="1.0.0",impl;uses:="org.osgi.framework,service";version="1
 .0.0"
Import-Package: org.jruby.embed;version="[1.7,2)",org.jruby.embed.osgi;v
 ersion="[1.7,2)",org.osgi.framework;version="[1.6,2)"
Tool: Bnd-2.1.0.20130426-122213

it's just have some basic jar configuration ,not OSGi bundle:

Manifest-Version: 1.0
Archiver-Version: Plexus Archiver
Created-By: Apache Maven
Build-Jdk: 1.6.0_45
Main-Class: activator.Activator

So ,how do I have to configuration ?

Solution

This is quite simple, add the following to your configuration:

<Embed-Dependency>dependencies</Embed-Dependency>

This is basically it. The complete documentation can be found at Felix-Maven-Bundle-Plugin and more details on how BND works can be found at aqute

Regarding, best practices of including. If it's something that just your application needs and is mostly hidden, embedding those dependencies can be a valid solution. If you are reusing this stuff you should think of creating a "shaded" bundle
