Hi,

ERRORLEVEL merely reflects errno, and that can change each time you execute a command

I think the problem is the /b in  exit /b %ANT_ERROR%

here is why 

$ perl -le" print system 'errorexit1.bat' "

$ exit 1
256

$ perl -le" print system 'errorexitb1.bat' "

$ exit /b 1
0

$

This tells me you are probably supposed to system antRun.bat or https://github.com/apache/ant/blob/master/src/script/antRun.pl
