Protos are duplicated

[vorburger]

While reviewing #1500 and #1502 from @mahanteshwar-git, I noticed that:

https://github.com/etcd-io/jetcd/tree/main/jetcd-core/src/main/proto

seems to contain similar (or possibly [hopefully; not verified] identical) *.proto files to:

https://github.com/etcd-io/jetcd/tree/main/jetcd-grpc/src/main/proto

and was wondering what that was so... seems confusing (at least to me).

That jetcd-grpc module does not contain any other (Java) code.

@lburgazzoli do you know what the background story here is / was?

Was the intention here perhaps to build the proto in one module, and have the other (core) then depend on it - but it was left unfinished?

[mahanteshwar-git]

yes, They are identical files.

It appears that the one in jetcd-grpc is used to generate the required java files necessary to invoke ETCD server endpoints.

[lburgazzoli]

The proto file in the core moduel are probably a leftover since the code generation happens in the grpc module https://github.com/etcd-io/jetcd/blob/main/jetcd-grpc/build.gradle#L28-L46

[mahanteshwar-git]

we can remove the one on jetcd- core
