如何在Mac OS X上使用Ant复制.app包？

Hey guys, I just had a quick question about copying files on Mac os x with ant. I've written myself a great little build script for my iPhone development. The script copies the compiled .app files that are created from xcodebuild. Anyway, the ant command does not seem to work. It does not copy the .app file correctly. it copies the contents of the .app file as if it were a folder. I understand that this is because its not preserving the meta data required to keep the folder a .app when copying. I can use ditto for the copy, but I'd like to know if there's something I'm missing with the ant command. So this is the summery of my question: How do I copy .app bundles with ant on mac os x? Any tips would be appreciated. Thanks, SamHey guys, I just had a quick question about cop
