Q and A on OSGI 6 release by BJ Hargrave: https://blog.osgi.org/2015/08/release-6-of-osgi-compendium-osgi.html

Question: It appears that the compendium jar you uploaded has a manifest entry that indicates it is only intended to be used at compile-time-only. Is this intentional? Is there a different jar I should be deploying at runtime?

Answer: Yes, it is intentional. The compendium jar was never meant to be used at runtime but people abused it anyway. So for R6 we have added an unresolvable requirement to prevent this. The latest Felix Http implementation (used as the RI in OSGi), already includes the OSGi http packages.

Don't install osgi.cmpn as a bundle. It wont resolve.

You should not use osgi.cmpn any more. It is recommended to use the individual API jars for each spec you use. To prevent people from installing (and resolving) osgi.cmpn, its manifest requires the osgi.unresolvable capability which the resolver can never satisfy.

If you must use osgi.cmpn as a compile scope dependency, then you would need to tell the resolved to never use it.

The best solution is to completely avoid osgi.cmpn

Note: I think Karthik had found other blogs that discussed the same idea. Effectively they are pushing for people to avoid osgi.cmpn.

From Karthik: "OSGI compendium (osgi.cmpn & osgi.compendium) is an aggregate API artifact of OSGI which is not available in Maven any more. We upgraded the version of compendium from 5 to 6 and 7 to solve the errors in the annotations (Symbol not found error) but it did not solve it. For our purposes, using individual artifacts for annotations as well as the wiring issues seems to be a better option."

There are two commits:

Reversion of commit ae6d5bc: https://bitbucket.org/nfreese/nowlanfork-igb/commits/5aafa33f854d1319f4efc23eb764cd884caa798a

Remove remaining references to osgi compendium: https://bitbucket.org/nfreese/nowlanfork-igb/commits/c8d6a9338e1803f6e243f1ec126d88625f513aa4

In one of my previous commits I had replaced bndlib with newer versions of osgi core and osgi compendium. While this seemed to satisfy the requirements for the annotations, it caused the error with osgi cmpn discussed above. I reverted the commit so that bndlib would be used instead. I then removed any remaining references to osgi compendium. IGB is able to build (mvn clean install) and I am no longer seeing the osgi.cmpn error when attempting to run the IGB jar.

To test: Pull the latest changes from the IGBF-3275 branch and build IGB.

Test Passes. I was able to build IGB with the new changes.
