Ceki, Hugues, Any comments on my work? Should I proceed that way for the other modules? Heiko On 16 September 2010 10:11, Heiko Seeberger <heiko.seeberger@googlemail.com>wrote:
Folks,
My first shot at OSGi work for slf4j-api can be taken from here (not yet ready for pulling into the main repo): http://github.com/weiglewilczek/slf4j/tree/osgi
Now the Felix Bundle plugin creates the manifest. It looks like below (not the plain manifest, but the output of analyzing with BND). As you can see all the issues I recently brought up are addressed, e.g. naming convention for Bundle-Symbolicname, execution environment bumped up to 1.4, etc.
As all the logging backends are fragments I excluded org.slf4j.impl package from imported packages. This means you can install the slf4j-api bundle in an OSGi container successfully without a backend. Not sure whether this is what we want.
Very important: The whole build still succeeds.
What do you think? Can we proceed this way?
