Only Maven repositories. No PDE. Plain OSGi application with my own launcher at runtime. At runtime there is no problem. This application is running for years and I have worked with OSGi for years now. I just have this trouble migrating to OSGi 7.0.0 and at compile / build time with Maven+Tycho.

And do you get the error at build time or when running your result? With Tycho you typically use PDE mechanisms to resolve dependencies, not maven dependencies. And what is your result? A plain OSGi application or a RCP application? Greez, Dirk Dirk Fauth <dirk.fa...@gmail.com <mailto:dirk.fa...@gmail.com>> schrieb am Fr., 3.

If so, which eclipse software site have you configured? Greez, Dirk Martin Petzold via osgi-dev <osgi-dev@mail.osgi.org <mailto:osgi-dev@mail.osgi.org>> schrieb am Fr., 3. Jan. 2020, 14:20: Dear Neil, thanks, but now we start again at the beginning at my first message (endless loop): I cannot set a dependency to "org.osgi:osgi.core" in Maven (with Tycho) because it requires 'osgi.unresolvable; (&(!(must.not.resolve=*))(must.not.resolve=*))'.

This is clear now. However, Ray told me to set the dependency for "org.eclipse.osgi" to "runtime" scope. But how can my implementation then depend on "org.osgi.framework" package during compile time? Either there is a separate API bundle from OSGi Alliance containing "org.osgi.framework" (which one is it?) Yes, this is the org.osgi:osgi.core dependency. That contains the pure api and no implementation, whereas org.eclipse.osgi is an implementation. Or you could just use org.eclipse.osgi at both compile time and runtime, but then you should be careful to avoid using equinox internal packages. or I should set the scope to compile instead of runtime? I am using the BundleContext and need access to this package. Thanks and kind regards, Martin Am 03.01.20 um 10:51 schrieb Mark Hoffmann via osgi-dev:Hi Martin, see comments inline.

Should I add "org.eclipse.osgi.services" or the individual "org.osgi.service.*" to my (parent) POM? Are the individual "org.osgi.service.*" also required at runtime (on classpath or installed to osgi?). Will "org.eclipse.osgi" start without "org.eclipse.osgi.services" on the classpath or installation as bundle?You have to distinguish between the packages you want to resolve and the artifacts/bundles that contain the the packages/implementations. In your case org.eclipse.osgi.services is the bundle that exports the packages org.osgi.service.* packages. Because Maven just resolves artifacts, you need to provide the bundle org.eclipse.osgi.services as dependency. Yes, org.eclipse.osgi will start without org.eclipse.osgi.servicesI have now added "org.eclipse.osgi.services". However, it now cannot requires "org.osgi.util.promise". What should I add to my POM in order to resolve the core Eclipse OSGi implementation (only OSGi core implementation)?You should find the promises and functions in the bundle org.eclipse.osgi.utilbtw I have removed the runtime scope for "org.eclipse.osgi".

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 <mailto:raymond.a...@liferay.com>> wrote: Yes and yes. OSGi started adding the unresolveable requirement at release 6 IIRC. So if you are using a prior releases of the companion jars (including cmpn, enterprise) they won't give you this failure, so you should upgrade. *Replacements:* Replace the compendium APIs with their respective individual api jars available on maven central, like this one [1].
