未能同步gradle項目：無法找到方法DefaultSourceDirectorySet

Question

我正在使用Android Studio 2.2.2並試圖從https://android.googlesource.com/導入存儲庫。

我在嘗試與給定文件的gradle同步時出現以下錯誤：

Gradle sync failed: Unable to find method 'org.gradle.api.internal.file.DefaultSourceDirectorySet 

我已經嘗試通過更新版本的protobuf給出here解決0.8.0但我得到更多的錯誤：Execution failed for task ':generateDebugProto'

這是gradle這個文件：

buildscript { 
    repositories { 
     mavenCentral() 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:2.1.0' 
     classpath 'com.google.protobuf:protobuf-gradle-plugin:0.7.0' 
    } 
} 

apply plugin: 'com.android.application' 
apply plugin: 'com.google.protobuf' 

android { 
    compileSdkVersion 23 
    buildToolsVersion "22.0.1" 

    defaultConfig { 
     applicationId "com.android.launcher3" 
     minSdkVersion 16 
     targetSdkVersion 23 
     versionCode 1 
     versionName "1.0" 

     testApplicationId "com.android.launcher3.tests" 
     testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" 
    } 
    buildTypes { 
     debug { 
      minifyEnabled false 
     } 
    } 
    sourceSets { 
     main { 
      res.srcDirs = ['res', 'WallpaperPicker/res'] 
      java.srcDirs = ['src', 'WallpaperPicker/src'] 
      manifest.srcFile 'AndroidManifest.xml' 
      proto.srcDirs 'protos/' 
     } 

     androidTest { 
      java.srcDirs = ['tests/src'] 
      res.srcDirs = ['tests/res'] 
      manifest.srcFile "tests/AndroidManifest.xml" 
     } 
    } 
} 

repositories { 
    mavenCentral() 
} 

dependencies { 
    compile 'com.android.support:support-v4:23.1.1' 
    compile 'com.android.support:recyclerview-v7:23.1.1' 
    compile 'com.google.protobuf.nano:protobuf-javanano:3.0.0-alpha-2' 

    testCompile 'junit:junit:4.12' 
    androidTestCompile 'com.android.support.test:runner:0.5' 
    androidTestCompile 'com.android.support.test.uiautomator:uiautomator-v18:2.1.2' 
} 

protobuf { 
    // Configure the protoc executable 
    protoc { 
     artifact = 'com.google.protobuf:protoc:3.0.0-alpha-3' 
    } 
}

嘗試更換您的GR的protobuf的部分adle文件，內容如下：

protobuf { 
    // Configure the protoc executable 
    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 { } 
      } 
     } 
    } 
}
