Before opening, please confirm:

• I have installed the latest version of the Amplify CLI (see above), and confirmed that the issue still persists.
• I have searched for duplicate or closed issues.
• I have read the guide for submitting bug reports.

npm

If applicable, what version of Node.js are you using?

v16.1.0

Amplify CLI Version

5.3.0

What operating system are you using?

Mac OS

Amplify Codegen Command

codegen models

Describe the bug

My repo has only a simple schema.graphql file
After generate java file for Reference and ReferenceIdTypeEnum class, the Reference.java is not compilable.

Expected behavior

The generated code should compilable

Reproduction steps

1. Run amplify codegen models in the same directory as schema.graphql
2. Check the output directory
3. Verify the class CopyOfBuilder is calling super.id() but there is no id() method in class.

GraphQL schema(s)

# Put schemas below this line
enum ReferenceIdTypeEnum {
    ASIN
    OBJECT_ID
}
type Reference {
    id: String!
    idType: ReferenceIdTypeEnum!
}

Log output

GraphQL schema compiled successfully.

Edit your schema at /Users/dantrong/workspace/src/androidMain/amplify/backend/api/cloudqueue/schema.graphql or place .graphql files in a directory at /Users/dantrong/workspace/src/androidMain/amplify/backend/api/cloudqueue/schema

Additional information

Here is the generated java file for Reference.java

    private CopyOfBuilder(String id, ReferenceIdTypeEnum idType) {
      super.id(id)
        .idType(idType);
    }
    
    @Override
     public CopyOfBuilder id(String id) {
      return (CopyOfBuilder) super.id(id);
    }
    
    @Override
     public CopyOfBuilder idType(ReferenceIdTypeEnum idType) {
      return (CopyOfBuilder) super.idType(idType);
    }
  }
  
}

The issue still exists. When running with the latest awsamplify-cli (npm i -g @aws-amplify/cli at 8.0.0), there is no IdStep interface in the generated file.

@aladine Could you check out your amplify/cli.json file for the following key-value? The expected value should be as following.

{
  "features": {
    "codegen": {
      "useappsyncmodelgenplugin": true
    }
  }
}

Thank you, @AaronZyLee.
Surprisingly it works now. I can see my output file generated exactly as the test case in #260
