Unexpected behaviour creating dynamic ANT task via XSLT and
executing via bat file
(Ant 1.8.2, XP SP3)
Background:
I’m using ANT to pipeline my conversion of XML (Excel) to PDF via the command line. So I chunked up the various steps into separate project files and import into the build.xml. At one point an XSLT created a bat file to copy required SVGs locally for use in the PDF. The bat file was executed using the <exec> task. A requirement came up to strip the DTD declaration out all the SVGs, so instead of creating a simple bat file to copy each SVG required it was changed to create a build file. In the build file are <copy> tasks and <filterchain> <tokenfilter> to strip out the DTD declaration. This ANT build does not exist as part of the main build.xml but executed within right after it has been created via XSLT. Hopefully that is clearer than mud.
So here is the unexpected or unusual (at least to me) behaviour. When the copy SVGs ANT build is executed and I hit ctrl C to stop the process to check the few files that have been copied over, the copy SVG build is still running in the background even though the main build.xml has been stopped. Is this behaviour correct and expected? I’m just curious more than anything and am not really looking for a solution. (To stop it copying I open the task manager and terminate the java task running.)

Thanks Vimil,
That explains it quite clearly and will give the subant task a try.

The reason for the behavior is because the batch file runs in a separate process. To prevent this behavior, instead of executing the batch file from the main build.xml, you can directly invoke the generated build.xml from the main build.xml using the subant task. Doing this makes the generated build.xml run in the same process as the main build.xml.
Hope my explanation helps
