Maven multi-module project mapstruct duplicate generation

Environment

• Operating System: Windows 10 22H2
• JDK version: openjdk 21.0.2
• Visual Studio Code version: 1.89.1
• Java extension version: v1.32.2024053108 (pre-release)

Steps To Reproduce

1. Create a Maven multi-module project with the following structure:
   ruoyi-parent

• ruoyi-admin
• • dependency: ruoyi-modeles/ruoyi-demo
• • dependency: ruoyi-modeles/ruoyi-system
• ruoyi-modeles
• • ruoyi-demo
• • • [mapper auto-generation here]
• • ruoyi-system
• • • [mapper auto-generation here]

2. Build the project.

Current Result

The mapper files are automatically generated in the generated-sources directory of both the parent and child modules.

Expected Result

The mapper files should be generated only in the respective module's generated-sources directory where the mappers are defined.
