Stop batch script from executing while encountering error

Question

So I'm building multiple client using the same batch script. If there's an error while building one, that process simply stops and continues with the next one. Because there's a lot of output on the screen and I'm doing other things, most of the time I miss that there was a build error.

Is there a way to stop executing the following tasks if there's an error, and show a popup message to get my attention? Or at least stop executing so when I come back to the command window I can see that there was a failure?

@echo off

if "%1"=="?" GOTO HELP

if NOT "%1"=="" set rev=%1
if NOT "%2"=="" set version=%2

@echo on
rem build one 
call perl buildClient.pl -brandName="myBrand" -group="group1" 

rem build two 
call perl buildClient.pl -brandName="myBrand" -group="group2" 

rem build three
call perl buildClient.pl -brandName="myBrand" -group="group3" 

rem build four 
call perl buildClient.pl -brandName="myBrand" -group="group4" 


    @echo off

    goto EXIT

    :HELP
    cls
    echo.
    echo.
    echo usage: buildbrand.bat [revision] [version] [group]
    echo.
    echo        ?           = this help screen
    echo.
    echo        revision    = build version
    echo                      Example: 5.2.31
    echo        group       = group of phones or phone name
    echo                      Example: SonyEricsson\K750
    echo.
    :EXIT
    set version=
    set rev=
    set brandName=
    PAUSE

Solution 1

"Check the errorlevel in an if statement, and then exit /b (exit the batch file only, not the entire cmd.exe process) for values of 1 or greater."

if %errorlevel% neq 0 exit /b %errorlevel%

Look here for details: How do I make a batch file terminate upon encountering an error?

Solution 2

The correct syntax for stopping execution if error is:

if ERRORLEVEL 1 exit
