I have the need to build uber jars of my projects ( to be able to easily transfer and execute on distributed computing systems like hadoop ).
I have been using Maven shade plugin <http://maven.apache.org/plugins/maven-shade-plugin/>successfully so far. i.e until I introduced the restlet:2.0 . The restlet jar is pulling in an osgi jar ( specifically org.osgi:org.osgi.core:jar:4. 0.0:compile) that is causing this error while i run my jar **************************** *Exception in thread "main" java.lang.SecurityException: no manifiest section for signature file entry OSGI-OPT/src/org/osgi/framework/PackagePermission.java* at sun.security.util.
