You should really get rid of the exec task and use the Ant sql task instead. It just requires a
JDBC driver.
Suitable parameters exist for all your args.

Hi,
Thank you to all for the suggestions. I have now got an ANT script that
checks the current database version and then runs a set of mysql scripts to
upgrade the database to the next version. What I am struggling with is when
it goes through the list="${db.upgrade.path.list}. On the first run the
folder exists and runs the scripts then on the second run it checks for the
next folder(it doesn't exist at the moment) and it should drop out echoing
the new current version but in my case it tries to run every occurrence as
per the list="${db.upgrade.path.list}. I want it to stop when it can't meet
the next condition. The output I am getting is as below:
