What is the easiest way to reset ERRORLEVEL to zero?
if you use exit /b 0 you can return an errorlevel 0 from within a child batch script without also exiting the parent.
Seems to do the trick:
ver > nulNot everything works, and it is not clear why. For example, the following do not:
echo. > nulcls > nul
In a pre- or post-build event, if the return code of an executable is greater than zero, and the call to the executable is not the last line of the pre- or post-build event, a quick way mute it and avoid triggering a check for a non-zero errorlevel is to follow the failing line with a line that explicitly returns zero:
cmd /c "exit /b 0"This is essentially a generic combination of the previously-mentioned solutions that will work with more than just the last line of a pre- or post-build event.
