I'm trying to set up my hudson project to integrate clover using Ant without having to change my build.xml. The build is fine until I add clover and I get the following:

Adding Clover Publisher with reportDir: clover
FATAL: hudson.util.DescribableList.add(Lhudson/model/Describable;)V
java.lang.NoSuchMethodError: hudson.util.DescribableList.add(Lhudson/model/Describable;)V

at hudson.model.Executor.run(Executor.java:122)

This is stopping me from finishing the set up. I've browsed the net and forums, but no one seems to have run into this issue. I'm currently on using plugin 2.5, with ant 1.7.1 and hudson 1.339.

Any help will be appreciated.

Many thanks
