msbuild PostBuildEvents复制（如果较新）

Question

Is it possible to define copy events in PostBuildEvents section which only copies the file if the file is newer?

<PostBuildEvent>
    xcopy "$(TargetDir)afile.extension" "$(TargetDir)..\afile.extension" <!-- anything possible which only copies if newer? -->
</PostBuildEvent>

Answer 1

Xcopy has a switch for doing just that. /D:mdy If you provide a date it will copy only files that were created after that date. If you don't provide a date it will copy only those files on the source that are newer than those in the target. You might want look at Robocopy,as it has many more options than xcopy.
