Comment 3 Raphael Groner 2013-08-06 16:14:22 UTC 
Okay, problem is localized. If "ant clean" has been run, then Eclipse must be manually notified via "Clean Projects ..." and deactivated "Build Automatically". Using different folders for each Ant and Eclipse does not make any difference (strange!).

I am not sure if this is a real bug. Eclipse does not seem to monitor the output folder for external changes and may discard the internal cache.

Besides that, I can reproduce the behaviour on Mageia2 with Eclipse Version: 3.7.1, Build id: R3_7_1, so this bug should better be forwarded to upstream.
