// This option provides a way to create a Junction instead of a
|
||
|
|
// Directory symlink on Windows. This comes with the following caveats:
|
||
|
|
// * NTFS Junctions cannot be relative.
|
||
|
|
// * NTFS Junctions MUST be directories.
|
||
|
|
// * NTFS Junctions must be on the same file system.
|
||
|
|
// * Most products CANNOT detect a directory is a Junction:
|
||
|
|
// This has the side effect of possibly having a whole directory
|
||
|
|
// deleted when a product is deleting the Junction directory.
|
||
|
|
// For example, JetBrains product lines will delete the entire contents
|
||
|
|
// of the TARGET directory because the product does not realize it's
|
||
|
|
// a symlink as the JVM and Node return false for isSymlink.
