that ok?
That's ok. If you look you'll see subset warnings for the other two:
aot-compile-rpm: warning: subsetted /path/to/3ddesktop-info-0.1.jar
aot-compile-rpm: warning: subsetted /path/to/3ddesktop-switch-0.1.jar
A subset warning basically means that all the classes in one jarfile
are contained in another. You only need one compiled copy of a class
on your system, so it doesn't bother to compile the duplicates.
