ant script not working

[Pradeep Kumar]

Hi,
I have a batch file in the current base directory. I tried running the batch file using the following command.

<?xml version="1.0" encoding="UTF-8"?>
<project name="batchFile" default="exec" basedir=".">
<target name="exec">
<echo>start execution</echo>
<exec dir="${basedir}" executable="batch" os="Windows NT">
<arg line="stop_copy_start"/>
</exec>

</target>
</project>

The echo is getting executed but there is no warning error or any intimation but the Build successfull message is getting displayed.
Can someone tell me how to run the batch file. THe os is windows xp service pack 2.

Thanks and regards,
Pradeep Kumar

Did you check the value of the "os.name" property?

How and where to test the os.name property.

Just add a

<echo>${os.name}</echo>

to your script. The shown value is the one you should use for the os attribute of the exec task. Or perhaps you should use the osfamily attribute instead.
