Asegurar que python is in the PATH where you're running the build, or specify an absolute path to your python executable in the exec tarea.

Review the docs for the tarea ejecutiva for any specific instructions on using windows vs. not-windows. Note that your specific error is mentioned there:

A common problem is not having the executable on the PATH. In case you get an error message Cannot run program "...":CreateProcess error=2. The system cannot find the path specified. have a look at your PATH variable. Just type the command directly on the command line and if Windows finds it, Ant should do it too. (Otherwise ask on the user mailinglist for help.) If Windows can not execute the program add the directory of the programm to the PATH (set PATH=%PATH%;dirOfProgram) or specify the absolute path in the executable attribute in your buildfile.
