Hello,
Actually it seems like the uDig developers just misnamed the file.  
It's a  gzipped tar archive, not a zip file.  I'm sure someone will 
fix this soon,  but until then a tar xvzf on the file works....
Cheers,

Dear All,
I am currently trying to follow the plugin tutorial for uDig. I am 
stuck  however as the linux version of the SDK  
(http://udig.refractions.net/downloads/udig-1.0.5-src.linux.gtk.x86.zip)  
is a corrupt archive. Pretty please, could somebody repackage the 
linux  SDK and post it?
If this is not possible, when/will the 1.1 stable version be 
released  and will the SDK  and plugin tutorial be released at the 
same time?
uDig looks like a fantastic platform to work with and I am excited 
about  creating an application with it. I hope I can contribute 
something back  in the process.
Kind regards,
Tom Bartlett
