The problem is the usetimestamp="false" which disables the local check.
And because its hard written in the (generated) code you can't "overwrite"
that with a <presetdef>.
I did a test with this buildfile:
- usetimestamp=false: loads everytime all artifacts (just the mkdir will run
once)
- usetimestamp=true: only load the 1st time
While I dont think that changing generated code is a good idea (when you
want to regenerate that later ...) this is the best thing I can suggest ...
(Another option: tweak Ant itself: overwrite <get> to ignore the
usetimestamp-setting, ...)
