Subject [jira] Commented: (GERONIMO-4525) No effective exit code for all Windows commands
Date Mon, 09 Feb 2009 08:32:59 GMT


Jack Cai commented on GERONIMO-4525:

Thanks Jarek for your help!

Ack to 1) & 2).

3) It is because the cmd executing the batch script exits with the exit code of the last executied
command, not the value of "errorlevel". Take geronimo.bat as an example, the last command
is "@endlocal", so the exit code will always be "0". Calling "cmd /cd exit /b %errorlevel%"
will set the exit code properly. This is helpful when the batch file is called from a program,
for example from a Java program (use Runtime.getRuntime().exec()).

Some other comment on your commit -

 - better add "cmd /cd exit /b 1" at line 253, to indicate user input errors
 - better add "cmd /cd exit /b 0" at line 309, to reset the errorlevel, because some previous
calls to "set XXX=" will result in errorlevel 1  :-(

 - better add "cmd /cd exit /b 1" at line 167, to indicate user input errors
 - remove unnecessary line 226-234

> There are multiple problems in the current Windows batch commands (including geronimo.bat,
startup.bat, etc.)
>  - It's not recommended to define an environment variable with the name ERRORLEVEL. See
>  - Set a value to ERRORLEVEL has no effect to the exit code of the batch command (so
the documented exit code "0" and "1" are not actually there).
>  - The value of the ERRORLEVEL variable will also get unset when the "@endlocal" command
is called.
