批处理脚本在异常情况下暂停，可以自动继续吗？

Question

I have the following snippet in a batch file to run a program with an argument in a loop:

for /F "tokens=*" %%a in (some-list.txt) do (
    java -jar some-java-package.jar com.example.package.class %%a
)

Sometimes the Java application crashes on a memory exception (this could be an important point, because according to my current programming experience these seem to be special exceptions and I was not able to catch them like I would catch normal exceptions in program code).

In such a case it seems my batch script pauses until I take action: I can press Ctrl-C and on batch's question if I want to stop the batch job respond N , then it will continue with the next program call.

Is it possible to tell batch to go on in such events automatically?

Answer 1

You should call java using the start command like this:

for /F "tokens=*" %%a in (some-list.txt) do (
    start "" /WAIT "java" -jar some-java-package.jar com.example.package.class %%a
)

The /WAIT switch lets start wait until the application ( java ) has finished execution.
The "" portion defines the window title (this is defined here since start sometimes confuses it with the command line when no title given).
