getSkipWhenSourceIsEmpty

Whether this task is skipped when its source contains no files and no directories.

When this is true, which is the default, a task with an empty source does not run and its destination directory is not synchronized. What is left in the destination then depends on whether it is a build-owned directory: if it is, the destination is cleaned up; otherwise it keeps the files the source no longer contains.

When this is false, the task always runs its copy action, so an empty source empties the destination. Note that this task always deletes the entire contents of its destination directory, not only the files it copied there, except for anything matched by preserve; disabling this extends that to a source that is empty, including one that is empty by mistake.
