Actually, I've read elsewhere that features included by features and features included by .product files cause an exact version to be specified. Looking at PDE's manifest editor for a feature, I don't see that a range can be specified for an included feature.
However, I may have stumbled on to a solution elsewhere. It looks like the trick to adding features to a product with a version range is to not specify them in the .product file but rather in the p2.inf. This is detailed by Andrew Niefer in his blog http://aniefer.blogspot.com/2009/07/composing-and-updating-custom-eclipse.html Now, in his example, he makes an exception for the platform. I.e., he includes it in the .product file, much like we do. This is what's causing the specific versions to end up in our p2 metadata. However, reading the fine print, it appears we could move the platform specifications to the p2.inf as long as we explicitly specify the platform's start levels, as per http://help.eclipse.org/indigo/topic/org.eclipse.pde.doc.user/tasks/pde_p2_configuringproducts.htm John |
