Hi guys, I want to know what causes this error when compiling...

It all started when I add a JPAContainer, I dont know if it has something to do with it but I can still run my project in a web browser without error. :mellow:

An annotation processor threw an uncaught exception.
Consult the following stack trace for details.

Looks like the annotation processing in EclipseLink has the same issue as some servlet containers have. Your problem is most likely solved by https://vaadin.com/directory#addon/vaadin-application-server-class-loader-workaround
