Re: [incquery-dev] xcore & eiq status
|
Try adjusting the Filters in the lower left corner to make sure not to filter out org.eclipse.*, as most of our code is in that namespace.
I have added you on https://bugs.eclipse.org/bugs/show_bug.cgi?id=428015
I have also added some comments that might give clues on how our builder performance could be significantly improved.

I tried to erase all the contents of the plugin.xml and invoke the builder again, and the contents have been written properly. Nevertheless, a full clean usually will result in the absence of the gen_package extension point definition and the query specification extension points. The derived feature extension points are always generated.
