If set, and Jenkins is set to poll for changes, Jenkins will honor any files and/or folders in this list when determining if a build needs to be triggered.

Each inclusion uses regular expression pattern matching, and must be separated by a new line. An empty list implies that everything is included.

	myapp/src/main/web/.*\.html
	myapp/src/main/web/.*\.jpeg
	myapp/src/main/web/.*\.gif
  
The example above illustrates that a build will only occur, if html/jpeg/gif files have been committed to the SCM. Exclusions take precedence over inclusions, if there is an overlap between included and excluded regions.
