What is the easiest way to reset ERRORLEVEL to zero?

Question

I have a post-build event that runs some commands for a c# project. The last command would sometimes cause the ERRORLEVEL value not equals to zero and then the build fails.

I want to append an extra line of command to always set the ERRORLEVEL value to zero. What is the most convenient way to do that?

Answer 1

if you use exit /b 0 you can return an errorlevel 0 from within a child batch script without also exiting the parent.

Answer 2

Seems to do the trick:

ver > nul 

Not everything works, and it is not clear why. For example, the following do not:

echo. > nul cls > nul
