Android gRPC Client 구현(1) - gradle 환경 설정

Android gRPC 통신을 위한 Client 구현을 위해서 google proto buf 및 proto file 빌드를 위한 gradle 설정이 필요하다.

 

1. gradle protobuf plugin 설정

 

apply plugin: 'com.google.protobuf'

 

2. protobuf build 환경 설정

 

buildscript{
    repositories{
        google()
        mavenCentral()
    }
    dependencies{
        classpath 'com.google.protobuf:protobuf-gradle-plugin:0.8.14'
    }
}

protobuf {
    protoc {
        artifact = "com.google.protobuf:protoc:3.12.0"

        // Set the location of generated source code by protoc compiler
        generatedFilesBaseDir = "$projectDir/gen-src"
    }
    plugins {
        grpc {
            artifact = 'io.grpc:protoc-gen-grpc-java:1.32.1'
        }
        grpckt { artifact = 'io.grpc:protoc-gen-grpc-kotlin:1.0.0:jdk7@jar' }
    }
    generateProtoTasks {
        all().each { task ->
            task.builtins {
                java { option 'lite' }
            }
            task.plugins {
                grpc { // Options added to --grpc_out
                    option 'lite' }
            }
        }
    }
}

 

3. protobuf 통신 및 proto class 참조를 위한 gradle 의존성 추가

 

implementation 'io.grpc:grpc-okhttp:1.38.1' // CURRENT_GRPC_VERSION
implementation 'io.grpc:grpc-protobuf-lite:1.38.1'
implementation 'io.grpc:grpc-stub:1.38.1'
implementation 'javax.annotation:javax.annotation-api:1.3.2'
