proto文件如何管理

按照文档建议，proto为一个单独的interface项目，其他项目引入这个interface项目时候，这个interface项目是生成好grpc所需的java class文件，然后提交到maven仓库，还是把interface作为 git的 submodule 引入呢，这两种方式哪种更合理一些

The issue asks how to manage proto files in a separate interface project, comparing generated Java classes published to Maven with a Git submodule. No repository files, tests, entry points, or concrete acceptance criteria are mentioned, so this requires maintainer guidance before implementation can begin.
