attribute. It=B4s passed to System.exit() which results (on windows) in
%ERRORLEVEL%.

Example:


build.xml
---8-<-------8-<-------8-<-------8-<-------8-<-------8-<-------8-<-------=
8-<----
<project default=3D"check">
    <target name=3D"check" depends=3D"-c1,-c2"/>
    <target name=3D"-c1" if=3D"status">
        <fail status=3D"${status}" message=3D"Return-Code: ${status}"/>
    </target>
    <target name=3D"-c2" unless=3D"status">
        <echo>Alles ok</echo>
    </target>
</project>
---8-<-------8-<-------8-<-------8-<-------8-<-------8-<-------8-<-------=
8-<----




check.bat
---8-<-------8-<-------8-<-------8-<-------8-<-------8-<-------8-<-------=
8-<----
@echo off
setlocal

set arg=3D-Dstatus=3D%1
if "%1"=3D=3D"" set arg=3D


call ant %arg% -quiet check
if %ERRORLEVEL% gtr 2 goto levelElse
goto level%ERRORLEVEL%

:level0

:level2

:levelElse
echo KATASTROPHE !!!
goto end



:end
endlocal
