Subject Re: Another samples issue ... how much does a user have to build?
Date Fri, 08 Aug 2008 14:17:10 GMT
I just upgraded the 2.1 samples branch (r683972) to use the updated 
genesis-1.5-SNAPSHOT build (which turns off the unique timestamps on 
snapshot artifacts.)

I'll work on updating the build to use the server's private repo 
artifacts later today and then will work on merging all these changes 
into the samples trunk.
