Junctions (linked folders) in the assets folder are only partially copied to the build output

Bắt đầu bằng cách tái hiện trường hợp Windows 10 với một junction bên dưới src/assets, sau đó so sánh cách build và serve xử lý thư mục được liên kết với đầu ra dist/assets. Hoàn tất khi các thư mục và tệp lồng nhau như myFolder/does not work.txt được sao chép, không chỉ các tệp nằm ngay dưới junction.

Is this a regression?

Did not work with ng 8 and does not work with ng 10. Did not check with 9 or anything before 8.

Description

When creating a junction inside the src/assets folder to another folder somewhere in the filesystem, the compiled output only contains the files that are directly beneath the linked folder. Any sub-folders in this linked folder are ignored by the compiler.

🔬 Minimal Reproduction

Tested on Windows 10:

1. Create an empty angular app with ng new assetsBugApp,
2. create a folder outside the application like "testAssets"
3. Inside "testAssets" create a textfile "works.txt"
4. Inside "testAssets" create a folder "myFolder"
5. Inside "testAssets/myFolder" create a textfile "does not work.txt"
6. Create a junction from "assetsBugApp/src/assets/test" to "testAssets" (eg mklink /J C:\tmp\assetsBugApp\src\assets\test C:\tmp\testAssets)
7. Run ng build
8. Look in the dist/assets folder. You will find the folder "test" containing "works.txt" but no "myFolder" and no "does not work.txt"

Anything else relevant?
Might be isolated to Windows environments.

Would be great to have this resolved, copying assets from A to B is less fun than linking them... :)
