I think you have come across a bug with Bug ID 4403166 in java.io.File.
Another longtime bugaboo for many developers, the issue with paths with more
than 255 characters on the Microsoft Windows operating system has finally been
resolved. Seems to be fixed in b19 of Mustang :-)
Seems to be a windows problem. You could move your workspace folder and all
subfolders to
c:\workspace, and run maven multiproject:site from that location. Hope this
helps.

Hmm.. How can they solve that, windows itself does not support it?
