I can reproduce this on my Mac by checking out JDT Core from the repository and then right-clicking on the manifest file and choosing "Plug-in Tools -> Create Ant Build File".

Exactly what I did. This is quite bad as I wanted to get the build scripts in order to test some builds.

Fixed in master.  The menu handler was always using the action to build the ant file for a feature, even if a plug-in was selected.  This change happened when we converted to using the menus framework.  I added separate handlers with appropriate activeWhen clauses and renamed some of the classes to reduce confusion.
