Hello,
We have Maven projects with Eclipselink 2.5.1 integration. Unit tests using Intellij stop working for me with error "Error:java: error: Annotation processor 'org.eclipse.persistence.internal.jpa.modelgen.CanonicalModelProcessor' not found". But it worked for me with Eclipselink 2.3 and still working using maven commands.
May be somebody have solution for this issue?
