Android Studio：无法在 build.gradle 文件中找到对 Android Gradle 插件的任何引用

Question

我尝试从 Eclipse 迁移到 Android Studio，但在 android studio 控制台中出现此错误：

13:52:44 Quick Fix Failed
         Unable to find any references to the Android Gradle plug-in in build.gradle files.
         Please click the link to perform a textual search and then update the build files manually.

这是我的 build.gradle 文件的内容：

apply plugin: 'android'

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    compile project(':ActionBar-PullToRefresh-master:ActionBar-PullToRefresh-master:library')
    compile project(':Crouton-master:Crouton-master:library')
}

android {
    compileSdkVersion 19
    buildToolsVersion "18.0.1"

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        // Move the tests to tests/java, tests/res, etc...
        instrumentTest.setRoot('tests')

        // Move the build types to build-types/<type>
        // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
        // This moves them out of them default location under src/<type>/... which would
        // conflict with src/ being used by the main source set.
        // Adding new build types or product flavors should be accompanied
        // by a similar customization.
        debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }
}

这是我的设置：

将此部分添加到您的脚本中。

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.8.+'
    }
}

值 0.8.+ 取决于您的 Android Studio 版本和您的 gradle 版本。
