Inside a batch file on Windows, I use 7-zip like this:

...\right_path\7z a output_file_name.zip file_to_be_compressed

How could I check the exit code of 7z and take the appropriate action ?

Test for a return code greater than or equal to 1:

if ERRORLEVEL 1 echo Error

or

if %ERRORLEVEL% NEQ 0 echo Error

or test for a return code equal to 0:

if %ERRORLEVEL% EQU 0 echo OK

You can use other commands such as GOTO where I show echo.

This really works when you have: App1.exe calls -> .bat which runs --> app2.exe

App2 returns errorlevel 1... but you need to catch that in the .bat and re-raise it to app1... otherwise .bat eats the errorlevel and app1 never knows.

Method:

In .bat:

app2.exe
if %ERRORLEVEL% GEQ 1 EXIT /B 1

This is a check after app2 for errorlevel. If > 0, then the .bat exits and sets errorlevel to 1 for the calling app1.

I had a batch script in Teamcity pipeline and it did not exit after it's child script did exit with code 1.

To fix the problem I added this string IF %ERRORLEVEL% NEQ 0 EXIT 1 after the child script call.

main-script.bat

...some code
call child-script.bat
IF %ERRORLEVEL% NEQ 0 EXIT 1
...some code

After the child script call exit result is saved to %ERRORLEVEL%. If it did exit with an error %ERRORLEVEL% would not be equal to 0 and in this case we exit with code 1 (error).

Try this: 

cd.>nul | call Your_7z_File.Bat && Goto :Next || Goto :Error

:: Or...

cd.>nul | ...\right_path\7z.exe a output_file_name.zip file_to_be_compressed && Goto :Next || Goto :Error

1) Set errorlevel == 0

cd.>nul

2) Redirect by | to simultaneously call Your_7z_File.Bat

cd.>nul | call Your_7z_File.Bat

3) Lets the output/errorlevel to a conditional execution && and || filter the next action

cd.>nul | call Your_7z_File.Bat && Goto :Next || Goto :Error

You can also test it in command line adding echo/:

cd.>nul | call Your_7z_File.Bat && echo\Goto :Next || echo\Goto :Error
