Re: [p2-dev] Generating multiple <update> elements for a <unit> (to handle feature rename)?

This is supported by using an p2ql expression in the update descriptor
Here is an example of such an expression:

providedCapabilities.exists(pc | pc.namespace == 'org.eclipse.equinox.p2.iu' && (pc.name == 'B' || pc.name == 'C'))

We want to rename a feature (from org.example.old.feature.group ->
org.example.new.feature.group) such that both users of the old feature
and older versions of the new feature can using Eclipse's "Check for
Updates" feature.

So far I have only managed to produce a single <update> element, though,
using the following:


     update.id = org.example.old.feature.group
     update.range = 0.0.0
     update.severity = 0

Any advice on how to specify multiple upgrade paths is greatly appreciated.

Best wishes,
