I see the same underlying exception,
I used:
} catch (InvocationTargetException t) {
throw new BuildException(t.getTargetException());
}
and saw:

I had a look into the source of <classconstants> -
all exceptions are

a new IOEx with the message only is thrown. Maybe
for debug purposes we

the complete stacktrace - especially here it could
be useful, I think.
I added them to see what is the exact exception. At
line 127 in ClassConstants.java I changed the catch
clauses to:
} catch (ClassNotFoundException cnfe) {
cnfe.printStackTrace();
throw new IOException(cnfe.getMessage());
} catch (NoSuchMethodException nsme) {
nsme.printStackTrace();
throw new IOException(nsme.getMessage());
} catch (IllegalAccessException iae) {
iae.printStackTrace();
throw new IOException(iae.getMessage());
} catch (IllegalArgumentException iarge) {
iarge.printStackTrace();
throw new IOException(iarge.getMessage());
} catch (InvocationTargetException ite) {
ite.printStackTrace();
throw new IOException(ite.getMessage());
}
By the way, I would also suggest these catch clauses
be replaced by one catch clause:
} catch (Exception e) {
e.printStackTrace();
//or
//getProject().log(e.getMessage(), Project.MSG_ERR);
throw new IOException(e.getMessage());
}
After rebuilding ant () and running the script from my
previous message, the output is

/home/rambius/drafts/ant/constants.xml:4: Unable to

As we can see there is a ClassFormataException,
obviuosly it does not recognize my class file as a
correct class file.
