If set, and Hudson is set to poll for changes, Hudson will ignore any revisions committed by users in this list when determining if a build needs to be triggered. This can be used to exclude commits done by the build itself from triggering another build, assuming the build server commits the change with a distinct SCM user.

Each exclusion uses literal pattern matching, and must be separated by a new line.

    	 auto_build_user

The example above illustrates that if only revisions by "auto_build_user" have been committed to the SCM a build will not occur.
