 4. Add/update tests in `CodegenExecutorTest` and fixtures under `src/test/resources/schema`.

+This project is organized as a single Maven module at the repository root:
 
 ## graphqlcodegen-maven-plugin
 This is the Maven plugin that users apply to their projects. It provides goals for generating Java (or Kotlin) code from GraphQL schemas, mirroring the functionality of the Netflix DGS Gradle codegen plugin. It is responsible for:
 - Accepting configuration via plugin parameters.
 - Resolving schema files from the local project and dependencies.
 - Invoking the DGS codegen library with the correct configuration.
 - Managing incremental code generation and manifest tracking.
