This is the log I am getting after upgrading my appengine sdk from 1.9.25 to 1.9.42.

I have tried all possible things to make it run. But still no class is getting enhanced.

I am in the same position. In eclipse it is imposible to enhance entity clases. I think it is a problem of the pluging with the new SDK library but no update is found when I try to update it.

We must to wait for an expert with an intellijent response or comment to our question.
