DOSCMD recursive COPY NUL fails with exit code 104

[kinook]

This seems to be a general problem when calling cmd /c FOR. One workaround is to put the FOR call in a batch file (which tests the exitcode itself and performs a no-op statement to force a 0 exitcode on success). This can be copied/pasted into VBP:



<step action='Write File' type='0'>
<Filename>%TEMP%\x.bat</Filename>
<Text><![CDATA[@FOR /R %TEMP% /D %%%%f IN (*.*) DO copy NUL "%%%%f\Vers_081.txt"
@IF %%ERRORLEVEL%% == 0 GOTO Done
@rem this executes another statement that will succeed so the callee gets a 0 exitcode
:Done]]></Text>
