Build only files that have changed

[jaime8111]

Every time a build my site with 11ty all the files are built again, even if they have no changed since the last build process.

I have a Google Cloud rsync process to upload all the files that have changed to my production environment. Now Google thinks that all the files have changed every time i build the site, because the date of the files are newer.

The expected behavior is that 11ty detect if each file is on the destiny folder, compare them, and only update it if their content is different.

Is it possible to do it now? If not, anyone knows any gulp process to get this done. Maybe to build on a temporal folder, and then compare the content of every file on temporal and build folder?

Thanks!
