Pagination Type cannot be referenced in nested type

Problem

Unable to generate Java class when using pagination type

Context

I am trying to use a pagination type as a field in a wrapper type and I have the following schema:

type TestObject {
    hello: MessageConnection
}

type Message @connection {
    name: String
}

As recommended in the docs, I had also configured the code generation by adding the following lines in my gradle file

generateJava {
  typeMapping = ["MessageConnection": "graphql.relay.SimpleListConnection<Message>"]
}

When I try to build the application, I run into the following error with the generated TestObject java class:

.../build/generated/com/generated/graphql/types/TestObject.java:3: error: ';' expected
import graphql.relay.SimpleListConnection<Message>;

When I reference the Pagination type on the Query type, it works perfectly fine, so I am not sure what I am missing here.

type Query {
  hello: MessageConnection
}
