Array Members: Minimum number of 0 items. Maximum number of 1 item.

Required: No

Includes

Specifies a list of filter rules that determines which files to include when running a task. The pattern should contain a single filter string that consists of the patterns to include. The patterns are delimited by "|" (that is, a pipe), for example, "/folder1|/folder2".
