Why my cmd program always be paused automatically?

When I use cmd(start->run->cmd) to run java ant build or something else program. Normally The command will run the program continuously until all tasks has to be done. on the process of runing, th开发者_高级运维e cmd consle will output specific some log continuously.

But My promblem is that the cmd always be paused automatically after few minutes. it will be restart if I phsyically enter any keystroke to awaken it up. it's really boring I need keep watch on the cmd.exe on all time.

Any way or configration to solve this, or any tools instead of windows cmd.exe to archieve the same function?

I can think of a couple of possible explanations:

1. Your Java application is pausing when it tries to read something from System.in.
2. You are actually running a batch file that uses the "pause" command at some point.

(FWIW: the cmd.exe program also implements pausing / continuing using CTRL-S / CTRL-Q, but (AFAIK) that requires you to physically enter the control characters from the keyboard ... and that's not happening.)
