Benson Margulies commented on MDEP-480:
---------------------------------------

Jonathan Volfson and I are working on this. I wanted to state the original 'mission' of this patch more carefully and see if the community is comfortable:

 

Consider a artifact (g:a) that has multiple files, either via classifiers or by type. Consider a directory on disk that contains _some_ of the files for this artifact. The effect of this flag is to allow the plugin to deliver the missing files without overwriting any existing files.

> There should be an option to prevent file overwrite when extracting files.
> This option is very helpful when unpack or unpack-dependencies happens after process-resouce phase. 
> Currently, there is overwriteRelease, overwriteSnapshot, overwriteIfNewer. But they all work on the artifact scope (that means decide if a whole artifact should overwrite), not files scope (if a file should overwrite an existing file).
