我的目標(biāo)是在我的項(xiàng)目中使用。通過使用演練，https://developer.lightbend.com/docs/akka-grpc/current/client/walkthrough.html 我試圖生成 Scala 文件。但是，每當(dāng)我（通過）構(gòu)建項(xiàng)目時，它都會生成Java文件而不是Scala文件。有沒有辦法生成Scala文件？我已經(jīng)嘗試過將Java轉(zhuǎn)換為斯卡拉，但它不起作用。下面是我的原型文件（與演練中的文件相同）：akka-grpcmvn clean packagesyntax = "proto3";option java_multiple_files = true;option java_package = "example.myapp.helloworld.grpc";option java_outer_classname = "HelloWorldProto";package helloworld;// The greeting service definition.service GreeterService {    // Sends a greeting    rpc SayHello (HelloRequest) returns (HelloReply) {}    rpc ItKeepsTalking (stream HelloRequest) returns (HelloReply) {}    rpc ItKeepsReplying (HelloRequest) returns (stream HelloReply) {}    rpc StreamHellos (stream HelloRequest) returns (stream HelloReply) {}}// The request message containing the user's name.message HelloRequest {    string name = 1;}// The response message containing the greetingsmessage HelloReply {    string message = 1;}
