Issue 1445 apply generated annotation

[aulea]

Solution for apache/grails-core#14506
Mark grails-GORM Traits methods as Generated and also with AST transformation added methods/constructors, so Jacoco could ignore them in its coverage reports.

When is this going to be merged? It's been waiting since april, so now someone needs to give it some care.
It's a blocker for anyone trying to use jacoco (because it's the only one that can handle compilestatic code) and gorm for coverage. Cobertura and openclover seem to have been abandoned.

Anyone? Without this you can't do meaningful coverage with grails, which in many cases is a requirement automatically disqualifying the framework from consideration.

Hi @puneetbehl ,

Is there any chance of getting this changed merged into the branch of grails-data-mapping being used by the latest grails? It looks like its been committed to the 7.0.x branch but not pulled into 7.2.x or above - lack of @generated is causing all our coverage reports to look horrible
