Bug: workflow ForTask will execute children one time even if there are no matching files #16

Closed Arkaedan closed 1 year ago

Arkaedan commented 1 year ago

Bug

The epsilon.for Ant task will execute once with the it property set to empty string when the fileset has no matching files.

Desired behaviour

The epsilon.for Ant task should not execute if the fileset has no matching files

Cause

If the fileset has no matching files, the task's getFiles() method returns a string array with one element, an empty string, instead of return an empty array
