Empty list of annotations attached to case class field

[YuriyMazepin]

Method Symbol_annots form TASTy Reflect returns an empty list for the field symbol of the case class. Before 0.25 release it worked as expected

Minimized code

final case class N(n: Int) extends annotation.StaticAnnotation

@N(100) final case class Basic1(@N(21) int: Int)

val t = summon[typeOf[Basic1]]
val symbol = t.unseal.tpe.typeSymbol

println( s"typeAnnots:  ${symbol.annots}")
println( s"caseFieldsAnnots:  ${symbol.caseFields.map(_.annots)}")

Output

typeAnnots: List(Apply(Select(New(Ident(N)),<init>),List(Literal(Constant(100)))))
caseFieldsAnnots: List(List())

Expectation

typeAnnots: List(Apply(Select(New(Ident(N)),<init>),List(Literal(Constant(100)))))
caseFieldsAnnots: List(List(Apply(Select(New(Ident(N)),<init>),List(Literal(Constant(21))))))

That's intentional, annotations on class value parameters go to the constructor to mimic the behavior of Scala 2: #8534
To get to them, you should be able to do something like:

// Get the symbols of the constructor value parameters
val valueParams = clsSymbol.primaryConstructor.paramSymss.find(_.headOption.fold(false)( _.isTerm)).getOrElse(Nil)
// Get the corresponding annotations
val annots = valueParams.map(_.annots)
