Sam, thanks for the reply. I'm not clear at this point how resolution:=optional works. My understanding (vague maybe) is bundle plugin will import all the packages which have been referred in the project. Out of the bunch, all might not be relevant during runtime. resolution:=optional will help my bundle to resolve this even if they are not supplied by other bundles.But isn't that we could do using ![package_name9] in import package if we don't want to include them?
Also, in your example, you've included the artifcatids explicitly in embed-dependency. It works if you are aware of them. My doubt is if I'm using a bunch of non-OSGI jars which internally refers to few other jars during runtime, then I don't have any knowledge of providing their artifcactids as an embed-dependency.
