I've tried to install SY SNAPSHOT on both Karaf and Fuse and I am getting:

Unsatisfied requirement(s):

---------------------------

   package:(&(package=org.switchyard.deploy.osgi.internal))

      SwitchYard: Karaf Commands

org.switchyard.deploy.karaf.ComponentList from switchyard-karaf-commands depends on org.switchyard.deploy.osgi.internal.ComponentExtension from switchyard-karaf-deploy. I could easilly fix the unsatisfied depndency by adding of the package org.switchyard.deploy.osgi.internal to switchyard-karaf-deploy's Export-Package. But I think that exporting "internal" package is not a good practice.
