If you'd like us to spend some time investigating, please take the time to provide a complete minimal sample (something that we can unzip or git clone, build, and deploy) that reproduces the problem.

hi， I've created a simple example to illustrate the problem, https://github.com/[1235wsg/example](https://github.com/1235wsg/example)

The stack trace terminates in the Querydsl annotation processor. Looking at their issue tracker, mapped supper-classes coming from library code seems to cause a bit of trouble. I suggest that you reach out to Querydsl directly as there's nothing we can do here.
