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=*))'.

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 <[email protected] <mailto:[email protected]>> 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].

The reason is that I need access to the "org.osgi.framework" package. I am using Maven (3.6) and Tycho (1.5.1) for building. The build platform runs Debian 10 and Java 11. *I get the following error:* Missing requirement: osgi.core 7.0.0.201802012106 requires 'osgi.unresolvable; (&(!(must.not.resolve=*))(must.not.resolve=*))' but it could not be found The "companion jars" are not meant for runtime and since resolving is a runtime operation (even when performed during build, i.e. deployment purposes) should not be included. *However, if I remove the dependency I get the following error:* Missing requirement: my.bundle 0.0.0.qualifier requires 'java.package; org.osgi.framework 1.7.0' but it could not be found This means you have no runtime framework available! Add a runtime dependency on the equinox framework: <dependency> <groupId>org.eclipse.platform</groupId> <artifactId>org.eclipse.osgi</artifactId> <version>3.x.0</version> <scope>runtime</scope> </dependency> // of course use tycho mechanism for above. *What is going wrong? How can I resolve this problem?* Stack Overflow: https://stackoverflow.com/questions/59563368/maven-tycho-cannot-resolve-osgi-core-bundle I'll answer there in a moment. - Ray Thanks and kind regards, Martin _______________________________________________ OSGi Developer Mail List [email protected] <mailto:[email protected]> https://mail.osgi.org/mailman/listinfo/osgi-dev -- *Raymond Augé* <http://www.liferay.com/web/raymond.auge/profile> (@rotty3000) Senior Software Architect *Liferay, Inc.* <http://www.liferay.com> (@Liferay)-- *Raymond Augé* <http://www.liferay.com/web/raymond.auge/profile> (@rotty3000) Senior Software Architect *Liferay, Inc.* <http://www.liferay.com> (@Liferay) -- *Raymond Augé* <http://www.liferay.com/web/raymond.auge/profile> (@rotty3000) Senior Software Architect *Liferay, Inc.* <http://www.liferay.com> (@Liferay)_______________________________________________ OSGi Developer Mail List [email protected] <mailto:[email protected]> https://mail.osgi.org/mailman/listinfo/osgi-dev-- Mark Hoffmann M.A. Dipl.-Betriebswirt (FH) CEO/CTO Phone: +49 3641 384 910 0 Mobile: +49 175 701 2201 E-Mail:[email protected] <mailto:[email protected]> Web:www.datainmotion.de <http://www.datainmotion.de> Data In Motion Consulting GmbH Kahlaische Strasse 4 07745 Jena Germany <https://www.google.com/maps/search/Kahlaische+Strasse+4%0D%0A07745+Jena%0D%0AGermany?entry=gmail&source=g> Geschäftsführer/CEO Mark Hoffmann Jürgen Albert Jena HRB 513025 Steuernummer 162/107/05779 USt-Id DE310002614 _______________________________________________ OSGi Developer Mail List [email protected] <mailto:[email protected]> https://mail.osgi.org/mailman/listinfo/osgi-dev_______________________________________________ OSGi Developer Mail List [email protected] <mailto:[email protected]> https://mail.osgi.org/mailman/listinfo/osgi-dev
