Hi, I just faced the same issue, https://bugs.eclipse.org/bugs/show_bug.cgi?id=326207 did not help (eclipse will not read the feature file after modification "Could not read: file:...").
Problematic feature file contains the following content :

   <requires>
   <!--
        All requirements to features and the content of the product are defined 
        in the product configuration epp.product since Eclipse Neon. For further
        details see the following bug:

        Bug 332989 - Allow parts of a package to upgraded or removed
        https://bugs.eclipse.org/bugs/show_bug.cgi?id=332989
     -->
   </requires>

Which did not help either.
I tried deleting the whole <require> block with no success.

This problem seem to exist since 2013 with various workarounds that do not work.

Versions :
- Eclipse IDE for Eclipse Commiters 4.7.1
- Acceleo 3.6.6 (.201610060831)

Did anyone have any luck with this problem ?
