= File System Watching

Gradle maintains a Virtual File System (VFS) to calculate what needs to be rebuilt on repeat builds of a project.
By watching the file system, Gradle keeps the VFS current between builds.

== Enable

Gradle enables file system watching by default for supported operating systems since Gradle 7.

 * Build root directories are always watchable hierarchies.
 * Watching the build root directories is better since they are less likely to be deleted and
 * nearly no changes to the watched directories are necessary when running builds on the same project.
 *
 * To allow deleting the build root directories, we need to stop watching a build root directory if there are no more snapshots in the VFS inside,
