Ant was shipping with virtual provides for certain dead subpackages for few years already.
As software collections are more and more common nowadays it was high time to drop them so
collections don't interfere with base platform.
The two most problems packages might see FTBFS due to no longer available ant-trax and/or
ant-nodeps - both were merged into main ant.jar since version 1.8.2 (December 27th, 2010).
If your package built just fine up to now but fails due to these changes the fix should be
just replacing BuildRequires: ant-[nodeps,trax] with BuildRequires: ant.
P.S. If you see a problem but you don't have the time or power to change it - let me
know and I'll use my proven packager to fix it.
