Which Feature Contains the Sources for SWT and JFace in 4.39+?

[ingomohr]

Over the last year the .source features that contained the SWT and JFace source had been removed from the Eclipse updatesites.

We have a Tycho-built Eclipse IDE (to automatically contain inhouse-made features, too) based on the current version 4.39, and we use p2 mirrors of:

https://download.eclipse.org/releases/2026-03/ and
https://download.eclipse.org/eclipse/updates/4.39/

as base.

I can see the jface.source bundle on the mirrored updatesite(s), but I don't know which feature I need to add to the eclipse.product file to add the sources to the Eclipse build.

Can you give me the id/name of that feature?
Or is there another approach now to include sources in an Eclipse build?

Thanks in advance!

Sorry, I should have created this in the discussions, not the issues.
