If you don't want the warnings with ant, in your javac task use
nowarn="on". By default you get the warning. This has nothing to do
with Eclipse. This is the way ant works.

You use 1.4.1 .class file on a 1.3 VM. This is not supposed to work.
Ant is using the same VM than the one you use to run Eclipse.

As far as I know, ant is using the same VM than the Eclipse one. So if
you run Eclipse on a 1.4 VM, ant runs on a 1.4 VM.

In this case, you might want to set the target option of your javac
task.
