I do all my development on windows, for unix "con" should be replaced on
"/dev/stdin".
You can hardcode this :) or just add a little code snippet to make this
target platform independent (I didn't test it on unix, so probably you have
to test it a little bit):
//get os name
var os = project.getProperty("os.name");
var console;
//select appropriate input
if(os.charAt(0) == 'W' || os.charAt(0) == 'w'){
console = "con";
}else{
console = "/dev/stdin";
}
//get standart input stream
var stdin = new BufferedReader(new InputStreamReader(new
FileInputStream(console)));
Just add this code to the target and remove duplicate line where new
BufferedReader is created.
Hope this help.

Hi,
this is extremely useful. Only one problem I ran this successfully under
windows which prompted for a password that I use to sign my jars with and
signed it. When I tried to use the same script under linux I get a file not
found exception because it can't find the file "con" ? which is asked for in
the stream handler. Any ideas ?
