In Ant 1.5, you cannot do this. The input stream of processes such as <java>
and <exec> is not connected to anything. You can redirect input by using the
external shell to redirect the input for you. This is pretty messy (i.e.
platform dependent).
In Ant 1.6, you can use a file or a property as input. If input is not
provided in this form and a task requests input it will be sent eventually to
the System.in stream. Currently, however, this is managed independently of
the output stream, which is buffered, so your prompt may still not appear.
I'm looking into that ...
