I have been working on trying to configure the DataNucleus enhancer to enhance JDO classes in a Java Google App Engine Gradle project. So far, I have been unsuccessful. I have tried using Gradle's ant integration to create an enhancer task in Gradle, and I've also tried this directly from Ant.
At this point, I'm now trying to do it manually, hoping that this might give me insight into what I'm doing wrong in Gradle and Ant.
However, the output from Java isn't very helpful either, and I'm hoping someone can tell me how I can get this to enhance my classes or tell me how I can find out what is causing the IllegalArgumentException.
Below is the output trying to enhance the classes. This command was actually reconstructed from digging through the Gradle logs in debug mode:
