Protobuf Android包含生成文件夹中的构建类型

我使用以下app.gradle从android示例项目中的.proto类生成java类 .

apply plugin: 'com.android.application'
apply plugin: 'com.google.protobuf'
android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId "protobuf.example.com.protobuftestapp"
        minSdkVersion 21
        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'
        }
    }
}
protobuf {
    protoc {
        artifact = "com.google.protobuf:protoc:3.0.0"
    }
    plugins {
        lite {
            artifact = "com.google.protobuf:protoc-gen-javalite:3.0.0"
        }
    }
    generateProtoTasks {
        all().each { task ->
            task.builtins {
                remove java
            }
            task.plugins {
                lite {
                    outputSubDir = ''
                }
            }
        }
    }
    generatedFilesBaseDir = "$projectDir/src/main/java/"
}
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.3.1'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    compile 'com.google.protobuf:protobuf-lite:3.0.0'
    testCompile 'junit:junit:4.12'
}

.proto文件如下所示：

syntax = "proto3";
package my_test_package;
option java_package = "protoclasses";
option java_outer_classname = "MyTestClass";
message TestClass {
    string test_string_a = 1;
    int32 test_int_b = 2;
    bool test_bool_c = 3;
}

生成类，但文件夹结构取决于buildType .

输出是

• src-> main-> java-> DEBUG - > protoclasses-> MyTestClass.java

• src-> main-> java-> RELEASE - > protoclasses-> MyTestClass.java

我搜索了几个小时，但没有设法剥离buildType文件夹 . 问题是，这些类是作为重复生成的，这会导致构建失败 .
