http://issues.apache.org/bugzilla/show_bug.cgi?id=28735 Copy and sync don't allow for low-resolution file times (SMB) Summary: Copy and sync don't allow for low-resolution file times (SMB) Product: Ant Version: 1.6.1 Platform: All OS/Version: All Status: NEW Severity: Major Priority: Other Component: Core tasks AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Copy and sync report a file out-of-date (and copy it) if the lastModified of the source is higher, even by 1 millisecond. When I sync an NTFS file system with a network share services by Samba (Samba 3 going to an ext2 or ext3 linux file system), the file time returned by the share is always a whole second, and when Ant tries to set the lastModified after a copy, the file time gets rounded down, so the source again looks newer by a few milliseconds. You should probably allow for at least 1 second fudge, at least as an option to resource-age comparisons. Here is a printout from a sync operation; I modified the sources to show the file times and difference; when I run this example, the file gets copied over and over again: C:\Documents and Settings\stoledo\Desktop\Projects\workspace3\myfiles_mirror>ant -verbose Unable to locate tools.jar.
