git push deployment with NodeJs/NPM project ignores files on sync

[MarioPerezEsteso]

When doing a git push in order to deploy an application, Kudu doesn't sync some files in node_modules because their creation date is always 26th october 1985. The git push is made to the folder site/repository and the sync is made to site/wwwroot, but as the timestamp of some files in the Node dependencies doesn't change, they are not copied.

Repro steps.

1. git push to the folder site/repository
2. npm install --production inside site/repository. It installs the dependencies and some of the files have creation date: 26th october 1985.
3. Kudu copies the modified files from site/repository to site/wwwroot. As Kudu looks for the files that have different timestamp, it doesn't copy some of them even when they have different content.

The log/error given by the failure.

There aren't errors. Kudu just ignores the files on the sync between site/repository and site/wwwroot.

System and versions

• Web Application using Windows.
• Node 12.15.0
• NPM 6.13.4

This issue is similar to this one, but doing a git push instead of a ZIP deployment.

Below is the current copying implementation. Please file gissue to KuduSync.NET to allow CopyAlways option. You will need to provide custom deployment as a workaround.
