Support Use Enum value in Annotations in Scala

[jxnu-liguobin]

Yes, I understand this but the problem is with

type User {
    name: String,
    friends: [User] @relationship(type: "FRIEND_WITH", direction: OUT)
}

enum Direction {
    IN,
    OUT
}

the import will not get triggered in the Scala world. Nowhere to be precise but Java does not complain about this.

Even adding a

directive @relationship (
    type: String,
    direction: Direction
) on FIELD_DEFINITION

won't help because the meta-information are not telling me anything about types in the annotation.
This would need a lot of refactoring -if even possible- to get those information.

Thus my initial question was if I should remove the assumptions in the Scala test code completely.

            <#list enumImportItSelfInScala as enum>
                <#if MapperUtil.isScalaCollection(field.type)>
                    <#if enum == MapperUtil.getGenericParameter(field.type)>
import ${enum}._
                    </#if>
                <#else >
                    <#if enum == field.type>
import ${enum}._
                    </#if>
                </#if>
            </#list>
        </#list>
    </#if>
</#if>

The problem here is that the value of the annotation is not judged.

Temporary solution: Enumeration values in annotations use enumeration full class names such as

@com.example.Relationship(type = "FRIEND_WITH", direction = DIRECTION.OUT)

Result: use enumeration full class names
