How to turn off DataNucleus Enhancer while working with Google App Engine
I am working in Eclipse on a Google AppEngine Java code. Every time I save a java file, the DataNucleus Enchancer starts off "Enhancement of Classes". Its quite irritating since it takes away focus when you are in full screen mode. Anybody knows how I can turn it off?
If I turn it off, will it affect my ability to deploy my application to App Engine from within Eclipse?
Answer
You can restrict which classes DataNucleus watches for changes so that it only re-runs the enhancement when your model classes actually change.
Go to the Project's properties, and select Google->App Engine->Orm. There you can specify patterns for the files to watch.
For example, I put all my model beans in a model/ subdirectory, so a pattern of src/**/model works for me. There are also example patterns under the 'Add' dialogue.
