Migration from Tycho 3 to Tycho 4.11 - Disable the 'osgi.service' capability check

[salvatore-coppola]

Hi there,

We (https://github.com/eclipse-kura/kura) are trying to migrate from Tycho version 3.0.5 to Tycho 4.0.11.
While building the reactor, building a bundle fails with the following message

[ERROR] Failed to resolve project dependencies:
[ERROR] Software being installed: org.eclipse.kura.core 2.0.0.202502210939
[ERROR] Missing requirement: org.eclipse.kura.core 2.0.0.202502210939 requires 'osgi.service; (objectClass=org.eclipse.kura.system.SystemService)' but it cannot be found.
[ERROR]
[ERROR] See https://wiki.eclipse.org/Tycho/Dependency_Resolution_Troubleshooting for help.

I'd like to disable this check to mimic the previous behaviour.
Is there a way to configure the tycho plugin?

Can you provide an integration-test to demonstrate the issue? Also keep in mind that even if you skip this it might not work at runtime, so can you not simply include one implementation here?

If we want to fix this I suspect we need to have a change in P2...

Ok, I'm trying to submit an IT test.
The strange thing is that only this bundle raises the error, it is the only one that uses the annotation instead of the xml description file. Do you think there is any connection?

Thanks.

Thanks

A testcase would highly appreciated!
I think you can set this to false to prevent Tycho from adding the additional requirement:

The setting solved the issue, thank you so much!
