I got very nice results when starting with -quiet mode.

+== Windows XP exec task : use os="Windows XP" instead of "os="Windows NT"
despite docs ==
+
+using ant 1.6.1 with j2sdk1.4.2
+
+Doc incorrectly says you should use os="Windows NT" for the exec task to lauch
a batch file
+
+If you try to launch a batch file with 'exec' task,
+you should try to use instead :
+{{{
+ <exec dir="bat" executable="cmd" os="Windows XP" failonerror="true">
+ <arg line="/c somebatch.bat"/>
+ </exec>
+}}}
+
+If you encounter such a problem, try a verbose execution:
+
+ant - verbose build.xml
+
+this should give you these results: (I've just tailored an adapted build.xml)
+
+{{{
+XP_as_NT:
+ [echo] batch.bat creation with content : '/c dir ..\ >dirNT.txt'
+ [echo] exec executable='cmd' os='Windows NT' failonerror='true'
+ [exec] Current OS is Windows XP
+ [exec] This OS, Windows XP was not found in the specified list of valid
OSes: Windows NT
+[available] Unable to find dirNT.txt to set property Success.XP_as_NT
+Property ${Success.XP_as_NT} has not been set
+ [echo] Success.XP_as_NT : ${Success.XP_as_NT}
+
+BUILD SUCCESSFUL
+Total time: 3 seconds
+}}}
+
+Compared to this one :{{{
+XP_as_XP:
+ [echo] Batch file creation with content : '/c dir ..\ >dirXP.txt'
+ [echo] exec executable='cmd' os='Windows XP' failonerror='true'
+ [exec] Current OS is Windows XP
+ [exec] Executing 'cmd' with arguments:
+ [exec] '/c'
+ [exec] 'batchXP.bat'
+ [exec]
+ [exec] The ' characters around the executable and arguments are
+ [exec] not part of the command.
+
+ [exec] F:\trucking\ant\bat>dir ..\ 1>dirXP.txt
+
+
+[available] Found: dirXP.txt in F:\trucking\ant\bat
+ [echo] Success.XP_as_XP : true
+
+BUILD SUCCESSFUL
+Total time: 3 seconds
+}}}
+
+Sadly enough, the env variable OS on Windows XP says : Windows_NT, and doesn't
reflect
+what you see on these verbose execution.
+
+The only simple way to determine os seems then with the windir env variable;
+which happens to be <somedrive>\WINNT on windows NT and <somedrive>\Windows on
windows XP
+
+You may test it that way:{{{
+<project name="YourProject">
+
+<property environment ="env"/>
+
+<target name="init">
+ <condition property="osIsXP">
+ <equals arg1="${env.HOMEDRIVE}\WINDOWS"
+ arg2="${env.windir}"/>
+ </condition>
+</target>
+}}}
