Invalid package name error when compiling generated zio-grpc classes on Scala 2.13.12

Question

I'm creating ZIO gRPC client service on scala 2.13.12.

I generated classes from .proto's and trying to compile my project and getting this error:

[error] C:\Users\arsen\IdeaProjects\voicekit-grpc\target\scala-2.13\src_managed\main\scalapb\tinkoff\cloud\stt\v1\SpeechToText\SpeechToTextProto.scala:10:20: object annotations is not a member of package com.google.api
[error]     com.google.api.annotations.AnnotationsProto,
[error]                    ^
[error] C:\Users\arsen\IdeaProjects\voicekit-grpc\target\scala-2.13\src_managed\main\scalapb\tinkoff\cloud\stt\v1\SpeechToText\SpeechToTextProto.scala:129:22: object annotations is not a member of package com.google.api
[error]       com.google.api.annotations.AnnotationsProto.javaDescriptor,
[error]                      ^
[error] two errors found

There is .proto file from API which I want to use in my app:

syntax = "proto3";

package tinkoff.cloud.stt.v1;
option go_package = "github.com/Tinkoff/voicekit-examples/golang/pkg/tinkoff/cloud/stt/v1";
option objc_class_prefix = 'TVKSR';

import "google/protobuf/duration.proto";
import "google/api/annotations.proto";

service SpeechToText { // Speech recognition.
  rpc Recognize(RecognizeRequest) returns (RecognizeResponse) { // Method to recognize whole audio at once: sending complete audio, getting complete recognition result.
    option (google.api.http) = {
      post: "/v1/stt:recognize"
      body: "*"
    };
  }
  rpc StreamingRecognize(stream StreamingRecognizeRequest)
    returns (stream StreamingRecognizeResponse); // Method for streaming recognition.

  rpc StreamingUnaryRecognize(stream StreamingUnaryRecognizeRequest) returns (RecognizeResponse) { // Method to synchronous recognize audio stream. Returns recognition result after all audio has been sent and processed.
    option (google.api.http) = {
      post: "/v1/stt:streaming_unary_recognize";
      body: "*";
    };
  }
}
......

There is my build.sbt:

import scala.tools.nsc.io.JFile

lazy val root = project
  .in(file("."))
  .settings(
    name := "voicekit-grpc",
    version := "0.1.0-SNAPSHOT",

    scalaVersion := "2.13.12",
    Compile / PB.targets := Seq(
      scalapb.gen(grpc = true) -> (Compile / sourceManaged).value / "scalapb",
      scalapb.zio_grpc.ZioCodeGenerator -> (Compile / sourceManaged).value / "scalapb"
    ),
    Compile / PB.includePaths ++= Seq(new JFile("third_party/googleapis/")),
    libraryDependencies ++= Seq(
      "io.grpc" % "grpc-netty" % "1.50.1",
      "com.thesamet.scalapb" %% "scalapb-runtime-grpc" % scalapb.compiler.Version.scalapbVersion,
      "com.typesafe" % "config" % "1.4.3",
      "dev.zio" %% "zio-http" % "0.0.5",
      "com.fasterxml.jackson.core" % "jackson-databind" % "2.16.1",
      "com.fasterxml.jackson.module" %% "jackson-module-scala" % "2.16.1",
      "com.thesamet.scalapb" %% "scalapb-runtime" % scalapb.compiler.Version.scalapbVersion % "protobuf"
    )
  )

There is my plugins.sbt:

addSbtPlugin("com.thesamet" % "sbt-protoc" % "1.0.6")

libraryDependencies ++= Seq(
  "com.thesamet.scalapb.zio-grpc" %% "zio-grpc-codegen" % "0.6.1")

I searched and manually downloaded external proto dependencies to directory /third_party

I've tried to add multiple paths to external dependencies to PB.includePaths, but it didn't help

Answer 1

Instead of manual downloading files try to add the dependency to build.sbt

"com.google.api.grpc" % "googleapis-common-protos" % "0.0.3" % "protobuf"

or

"com.google.api.grpc" % "proto-google-common-protos" % "2.34.0" % "protobuf"

Please notice % "protobuf" scope.

Actually, just add google annotations.proto and http.proto manually to src/main/protobuf/google/api.

Import "google/api/annotations.proto" was not found or had errors. How do I add it as a dependency?
