Generate Relay Connection (Version: 3.0.0)

Issue Description

I am using GraphQL Java Kickstarter’s relay function. See https://www.graphql-java-kickstart.com/tools/relay/ I have below schema:

type Query {
    users(first: Int, after: String): UserConnection @connection(for: "User")
    organizations(first: Int, after: String): OrganizationConnection @connection(for: "Organization")
}

type User {
    id: ID!
    name: String
}

type Organization {
    id: ID!
}

Steps to Reproduce

In a Java project, under gradle, setup basic graphql-java-codegen config, copy the above schema to resources as .graphqls file, run Gradle task graphqlCodegen

Expected Result

Generate model classes UserConnection and OrganizationConnection The associated query should have signature

public Connection<User> users(int first, String after, DataFetchingEnvironment env);

Actual Result

The model classes are missing.

UserConnection users(Integer first, String after, graphql.schema.DataFetchingEnvironment env) throws Exception;

Your Environment and Setup

• graphql-java-codegen: 3.0.0
• Build tool: Gradle
• Java tool: openjdk version “14.0.1”

@kobylynskyi Sorry for messing things up. I was working on to get a custom relay up to working and I mistyped. The point of this bug ticket/issue should be to adhere to official relay specification and hence, the interface should return Connection<User> More info on why relay should be used can be viewed here https://www.howtographql.com/react-relay/8-pagination/
