When running a build that gets the latest version from VSS the following error
occurs:

<path to srcsafe.ini> is a directory. Please specify the location of srcsafe.ini

From version 1.3 of the VSS plugin, looking at VSSSCM.java, on line 305, it
checks whether the serverPath variable is NOT a directory, and then throws an
IOException the above message. I believe the check should be for whether the
serverPath variable IS a directory.
