Description Scheiber Erno 2010-12-29 10:06:38 UTC 
The <java> task does not allow to run a class with code like
=========================
import java.util.Scanner;
....
Scanner scanner=new Scanner(System.in);
long a=nextLong();
....
=========================
This was OK in ant 1.8.1.

Seems to be working for me with 1.8.2 on Ubuntu with fork="true". What exact OS are you running? Do you have a complete test case to reproduce?

Reproducible with that script on Linux; the test program does get the input, but only after sending Ctrl-D.

Not sure what specifically changed in 1.8.2 but in general you should not use <java> to run programs with nontrivial stdio, since Ant processes it to fit into the logging system.
