There is apparently a problem with the way the NetBeans Explorer allows the
user to add jar files or directories to the NetBeans repository through the
`Project Settings` tab.  When I go to add a jar file, the Explorer adds a
`.` to the repository list, but I am unable to define the path to the jar.
When I go to add a directory to the reposity, the Explorer adds a
`Unreachable file system(.)` but again I am unable to map a directory in the
repository.  The end result is that I am unable to add jars or directories
to the repository through the `Project Settings` tab.  Am I alone on this?
