A bit of rational about why companion jars are unresolvable: The OSGi specs are to a very high degree independent from each other. There's no reason for you to be forced to use all R5 specs, or all R6 or whatever. Those are simply marketing versions.
What you are really using are the individual specs at a given version. For example using DS 1.4, Event 1.0, and logging 1.2 is perfectly fine combination given you can find providers of each that work together well. The APIs themselves won't care. However some providers actually package OSGi spec APIs which they provide implementations for, which means if you include the aggregate companion jars also at runtime you may have two API versions to contend with. You may inadvertently expose yourself to a wrong API version, hence why they will no longer resolve. - Ray On Thu, Jan 2, 2020 at 12:36 PM Raymond Auge <raymond.a...@liferay.com> wrote: > Yes and yes. > > OSGi started adding the unresolveable requirement at release 6 IIRC.
