[ImageJ-devel] Trouble Building the Maven Project for ImageJ

[Curtis Rueden]

Hi Calem,

I was able to duplicate the problem in my Windows VM. The problem is now
fixed with the latest code on the master branch. (If you are curious: the
bug resulted from Windows's convention of backslash rather than forward
slash for directory separator.)

Please let us know if you still have any trouble!

Regards,
Curtis
