No scalar implementation when using a external JAR

[Mcdostone]

Hello, I have 2 gradle projects:

• hello-graphql defining all the graphQL schemas,
• hello-app, the spring boot application using hello-graphql

hello-graphql defines a custom scalar year. It is used in the Person graphQL definition.

Issue

I am facing issues when I want to use this library in my spring boot application:

***************************
APPLICATION FAILED TO START
***************************
Description:
There are problems with the GraphQL Schema:
        * There is no scalar implementation for the named  'Year' scalar type

It seems that Spring boot is not able to detect the Year scalar.
I use codegen since my graphQL definitions are in a external JAR.

To reproduce

git clone https://github.com/Mcdostone/hello-graphql
cd hello-graphql
./gradlew clean build
./gradlew :hello-app:bootRun

Thanks for your help

Hi @Mcdostone, if you are adding a custom scalar type like this you need to define an implementation for the scalar with @DgsScalar.
