Ant is running an out-of-date task class -- why? [message #212139]

I have a small Java program which populates database tables with test
data. I am running this program from Ant using a <taskdef> in the target.
I launch this Ant task with Eclipse using the External Tools button.

I have recently updated the Java class in order to add different test data
to the tables. However now when I run the Ant task the old class gets
executed and the old test data is inserted into my database tables. This
happens no matter how many times I restart Eclipse or rebuild my project.
It appears that the original class is still present in some directory that
Ant uses in its classpath, and this out-of-date class is taking precedence
over the new version. The new class is present in the classpath which I
assign in build.xml. I can find no instance of the previous version of
the class which Ant is running instead of the current version.

One thing of interest is that when I run the Ant task in Eclipse I get a
message telling me "Waiting for virtual machine to exit" -- I'm not sure
what this means but perhaps it has some significance?

My task is defined in the Ant target like so:

<target name="populate"
description="Creates and persists some sample Ioi, Trader, and
Firm objects">
<taskdef name="populateTables"
classname="com.mycom.focus.tools.PopulateTables"
classpathref="project.class.path">
</taskdef>
<populateTables/>
</target>

If anyone can shed any light on this for me I'd certainly appreciate it.
Thanks in advance!

Sorry nothing jumps out at me.
What are you actually including in your project.class.path? Do you have a
JAR that is out of date?

Thanks for looking at this Darin.

The problem turned out to be a bonehead mistake on my part. I have both a
main() and an execute() method in my class. The execute() is just a copy
of the code in main(), and when I modified the class I modified the code
in main() without making the same changes to execute(), which is the
actual method that Ant is running. Now that I have made the changes in
execute() all is well again in the universe.
