Could you post your Diagnostic.java code?
I think your best bet to solving the <classcontants> issue is to dig under the hood of its code and see what makes it tick and experiment. Or, certainly simpler, write a custom Ant task that gets the information from Diagnostic and sets and Ant property. It'd only be a few lines of code to do this - extend from Task, implement a public void execute() method, get the value you want, and call project.setNewProperty(...).

Yes, my constants are "public static final". The problem, I found, is that the definition of VERSION is a method evaluation, not a compile-time constant, as you had tried. So that answers that question.
The remaining issue is back on the file that I really want to use, Diagnostic.class. Changing nothing except the class name & path to point to this file causes an IOException, so it looks like a bug to me. Who does one inform of such things?
BTW, Erik thanks for your <prefixlines> tip regarding constants!

Instead of my Diagnostic.class I tried a simpler Version.class and then I received no error, even *without* bcel.jar. So this seems like a data-dependent bug...
Did you make your VERSION be "public static final"? I just tried it (had to download and install BCEL into ANT_HOME/lib myself) with this class:
public class Test { public static final String VERSION = "version"; }
I also tried it with an int:
public static final int VERSION = 123;
with this build file snippet:
<loadproperties srcfile="build/Test.class"> <filterchain> <classconstants/> </filterchain> </loadproperties> <echo>${VERSION}</echo>
(2) As I could successfully execute with my Version.class, how do I then *access* the properties? I have a constant named VERSION. I tried <echo> with "${VERSION}" and with "${com.cleancode.data.Version.VERSION}" but neither had a value. What are the rules for the name of a property from a class file?
the property name is the constant name, no package prefix is added. Though a slick trick is to use a <prefixlines prefix="constants."/> after <classconstants>.
My guess is your property is not public static final.
