Update HarvestSCM.java

Adicionado o parâmetro "option" do Harvest, sem este parâmetro o jenkins/hudson não consegue criar os diretórios, assim que você cria um novo job.
O default será -pc, conforme a documentação do hco.
-op option
(Optional.) Specifies where files or items should be placed in relationship to the specified view path or client directory structure.
Specify one of the following options:

pc
Preserve and create path structure—Checks out selected files to paths with names that correspond to their client directory location, and creates any view paths that do not currently exist.
as
All files to same view path—Checks out all selected files to the same path in the destination view, ignoring the client directory structure.
