NOTE: Although `FileTree` extends `FileCollection` (an is-a relationship), their behaviors differ.
In other words, you can use a file tree wherever a file collection is required, but remember that a file collection is a flat list/set of files, while a file tree is a file and directory hierarchy.
To convert a file tree to a flat collection, use the link:{javadocPath}/org/gradle/api/file/FileTree.html#getFiles--[FileTree.getFiles()] property.

     *
     * <p>The returned file tree is lazy, so that it scans for files only when the contents of the file tree are
     * queried. The file tree is also live, so that it scans for files each time the contents of the file tree are
     * queried.</p>
     *
     * <p>The order of the files in a {@code FileTree} is not stable, even on a single computer.
     *
     * @param baseDir The base directory of the file tree. Evaluated as per {@link #file(Object)}.

[[tar_tree_no_backing_file]]
==== TAR trees from resources without backing files

It is possible to create TAR trees from arbitrary resources.
If the resource is not created via `project.resources`, then it may not have a backing file.
Creating a TAR tree from a resource with no backing file has been deprecated.

The updateExprType method is used to record this final type and update
the recorded types: the type-checked expression tree is again traversed down,
and the new type is propagated as needed. Untyped constant expression values
that become fully typed must now be representable by the full type (constant
sub-expression trees are left alone except for their roots). This mechanism
ensures that a client sees the actual (run-time) type an untyped value would
