proto文件如何管理

[bli22ard]

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

IMO you should build the interface project once and upload it to a maven repository. That way you have control about versioning it, and for the other developers it is just a library like any other.

Does that answer your question?

如果proto每次生成后提交到maven仓库， 那么开发过程中， 就需要先将proto 生成 jar ， 上传到maven仓库，这样maven仓库就会有开发阶段的 proto 的jar，这样是不是不利于maven仓库的 jar 版本管理

[ST-DDT]

• So first you only upload the proto file to maven,
• then you download it from there
• and build the proto/grpc jar
• and upload that to maven
• and use those for development?

Why do you separate the proto files from the jar upload? Different distributors/team?

If you only need the jar for one project, then you can just build it as part of your project.
If you need it multiple times, then you should add a build pipeline that builds and uploads it for you.

Storing it in maven saves you build time and config while it may have a dependency on specific protobuf and grpc version ranges due to internal API usage in the generated code.
I never really had much issues with that though.
