Todd Lipcon commented on HDFS-1935:
-----------------------------------
usetimestamps="true" doesn't appear to do it... perhaps it avoids
re-downloading, but I think it still goes and at least sends a "HEAD" request.
The <condition> is a good idea... perhaps I'll take a crack at it.
> Build should not redownload ivy on every invocation
