android studio 加载.proto不能生成xxxDrpc的问题

第一步protobuff插件的下载，
第二步 gradle的配置两个 app gradle的配置
apply plugin: 'com.android.application'
apply plugin: 'android-apt'
apply plugin: 'com.google.protobuf'

android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "cn.efarm360.com.animalhusbandry"
minSdkVersion 14
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
lintOptions {
disable 'InvalidPackage'
}
configurations.all {
resolutionStrategy.force 'com.google.code.findbugs:jsr305:3.0.0'
}
}
protobuf {
protoc {
artifact = 'com.google.protobuf:protoc:3.0.2'
}
plugins {
javalite {
artifact = "com.google.protobuf:protoc-gen-javalite:3.0.0"
}
grpc {
artifact = 'io.grpc:protoc-gen-grpc-java:1.0.2' // CURRENT_GRPC_VERSION
}
}
generateProtoTasks {
all().each { task ->
task.plugins {
javalite {}
grpc {
// Options added to --grpc_out
option 'lite'
}
}
}
}
}

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.google.code.findbugs:jsr305:3.0.0'
compile 'com.google.guava:guava:18.0'
compile 'com.squareup.okhttp:okhttp:2.2.0'
compile 'com.android.support:appcompat-v7:25.0.0'
testCompile 'junit:junit:4.12'

// You need to build grpc-java to obtain these libraries below.
compile 'io.grpc:grpc-okhttp:1.0.2'
// CURRENT_GRPC_VERSION
compile 'io.grpc:grpc-protobuf-lite:1.0.2'
// CURRENT_GRPC_VERSION
compile 'io.grpc:grpc-stub:1.0.2'
// CURRENT_GRPC_VERSION
compile 'javax.annotation:javax.annotation-api:1.2'

}
tasks.withType(JavaCompile) {
options.encoding = "UTF-8"
}

外部gradle的配置 buildscript {
repositories {
maven{ url 'http://maven.aliyun.com/nexus/content/groups/public/' }
maven{ url 'https://code.lds.org/nexus/content/groups/main-repo/' }
maven{ url 'http://maven.ibiblio.org/maven2/' }
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.2.3'
//注解的使用
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
//grpc的使用
classpath "com.google.protobuf:protobuf-gradle-plugin:0.8.0"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files

}
}

allprojects {
repositories {
maven{ url 'http://maven.aliyun.com/nexus/content/groups/public/' }
maven{ url 'https://code.lds.org/nexus/content/groups/main-repo/' }
maven{ url 'http://maven.ibiblio.org/maven2/' }
jcenter()
mavenLocal()
}
}

task clean(type: Delete) {
delete rootProject.buildDir
}
第三步proto文件夹的建立。
