I get this issue pretty often too, although my experience is that you likely have an issue with one of your entities (sometimes your entity can be properly coded, but there could be a fluke with how DataNucleus +GAE interpret a particular feature/annotation, especially with JPA).
For example, I had an entity that would fail DataNucleus validation at first, but when I would do a "Clean All"+"Auto Build", the Datanucleus error would go away until some other class (any java class) was re- compiled. I ended up discovering this by iteratively removing JPA features from my Entity one at a time (@OneToOne relationships, etc) until the "this class not enhanced" errors went away). Eventually I was able to nail down that I was either annotating something incorrectly or DataNucleus/GAE didn't support a particular feature, or in one case an actual bug. Not exactly a clear-cut answer, but that's the path I took. How complex are your entities? david On Mar 11, 7:21 pm, Sekhar <sek...@allurefx.com> wrote: > I'm using the Eclipse Google plugin, and every once in a while after a > build I get the dreaded "this class is not enhanced!" errors for all > my entities (even when I don't edit any of them).
