In Linux environment, if some files' owner are somebody else, but say my userid is in the group owner of these files. If I copy files over these files, the owner of these files are not changed.
In ant, if I use copy task, these files' ownership will be change to my userid .
I am wondering why? Can somebody give me an explanation?
Ant was written in Java and Java, by design doesn't support OS-specific stuff like file ownerships. Effectively, you get the same rights on the results of the copy that you would if you wrote a standalone Java app that created a new file and copied the contents of the source file into it.
