Exec task does not stop after program error.

["Pierre, Sebastien" <sp...@rational.com>]

Hi folks!

Here's a weird stuff : ant doesn't stop when you exec a program that
returns an error.
For example I have a python script that validates a bunch of XML files,
and I'd like my makefile to stop when my script returns an error code -
but ant just doesn't care and continues - which leads to unecessary
processing.

I think it would be cool to have an option in the exec task that would
just let us specify if we care or not about the execution's result [as a
way to set some env vars for the command]. BTW, why do ant need a
platform-dependant shell-script to start a command ???

Thx,
Seb.

I'm gonna die !!!!!
How is it possible that you cannot change the current dir of a process
????? This is just horrible....I have been looking for something like
that because I have an application that loads external scrips that can
include other scripts with a relative path....so I have to 'cd' to the
script path before loading it to make the script's dependencies
satisfied. 

What about the 'user.dir' property - does it really sets the path for
the whole VM ? Is it a reliable method ?

Thanks,
Seb.

Yup, going to add an option for that.

Because there is no way in Java to change the working directory of a
Process before you start it - contrast this with the dir attribute of
Exec.
