with regards milano

you have add meta-annotation annotation-type. joincolumn try this:

import annotation.target.field  @(joincolumn @field)(name = "useraccount_id") 

you can define type aliases, e.g.:

object myannotations {   type joincolumn = jpa.joincolumn @field } 

and import these annotations instead of original ones. see also: https://issues.scala-lang.org/browse/si-3421
