INVALID_ARGUMENT: Failed to convert to class about grpc-wiremock

[Adven27]

I've placed test.proto file with content from your comment to example/proto dir:

$ cat example/proto/test.proto 
package test.v1
import "google/protobuf/timestamp.proto";

option java_multiple_files = true;
option go_package = "testv1";
option java_package = "com.test.v1";
option java_outer_classname = "V1Proto";

message Employee {
  string name = 1;
  string id = 2;
  google.protobuf.Timestamp time_stamp = 3;
}

And run the container:

$ docker run -p 8888:8888 -p 50000:50000 -v $(pwd)/example/proto:/proto adven27/grpc-wiremock
Initialized native services in: /home/gradle/.gradle/native

Here are the errors from proto compiler:

@deepnirmal do you sure your proto is valid?

After fixing this message Please use 'syntax = "proto2";' or 'syntax = "proto3";' to specify a syntax version. and this one test.proto:2:1: Expected ";". file looks like this:

$ cat example/proto/test.proto 
syntax = "proto3";
package test.v1;
import "google/protobuf/timestamp.proto";

option java_multiple_files = true;
option go_package = "testv1";
option java_package = "com.test.v1";
option java_outer_classname = "V1Proto";

message Employee {
  string name = 1;
  string id = 2;
  google.protobuf.Timestamp time_stamp = 3;
}

and container has started:

$ docker run -p 8888:8888 -p 50000:50000 -v $(pwd)/example/proto:/proto adven27/grpc-wiremock
