hi all,
I use Apache Ant version 1.7.0.
And I use ant archive tasks to get ABC.ear.
I need to compare size of output archives(ABC.ear) with older one in order to realize any of changes.
When I run the build.xml one after another(the same build.xml), Although there is no file is edited or added or replaced, my ear file size is changed. Is there any problem with , tasks archiving method? is this a bug?
Thanks your help.

Best regards.
