Re: [grpc-io] combination of protoc version, protobuf-java, and grpc-java

['Eric Anderson' via grpc.io]

It sounds like you aren't using Maven or Gradle.

For the generated code, if generating code with version X of protoc or the
gRPC plugin, you need to use the corresponding Java components (runtime) at
version X or later.

You are using protoc 3.19.0, so you need to use protobuf-java 3.19.0 or
later. Similarly, if you were using protoc-gen-grpc-java 1.43.0, you'd need
to use grpc-protobuf 1.43.0 or later. For simplicity the versions of the
code generator and the runtime generally match; newer runtimes support
older generated code to allow combining generated code from multiple
sources (libraries) and isn't all that important when you are running the
generator and choosing the runtime version yourself.

[grpc-io] combination of protoc version, protobuf-java, and grpc-java

[Ronak Prajapati]

Hi Team,

How can I find 

*right combination of protoc version, protobuf-java, and grpc-java.*

can you suggest me this and how can I download it I want to use it in  my 
standalone application. 

I will build my own script build protoc and then wamt use GRPC library to 
send it from client to server.

right now I am facing below issue,

*!com.google.protobuf.GeneratedMessageV3.isStringEmpty(userAccountUniqueId_)*
Where I am using *protoc-3.19.0-win64 and protobuf-java-3.17.2 jar*

In which this isStringEmpty method doees not exist. But protoc is 
generating this code.
