Android Studio Gradle 无法解析符号 'applicationVariants'

Question

我正在尝试解决 Gradle 的一个恼人问题，该问题不允许库具有不同的 min/target sdk。解决方案是将以下内容添加到 build.gradle。

android.applicationVariants.all{ variant ->
    // This is an annoying hack to get around the fact that the Gradle plugin does not support
    // having libraries with different minSdkVersions. Play Services has a min version of 9 (Gingerbread)
    // but Android Maps Utils supports 8 (Froyo) still
    variant.processManifest.doFirst {
        File manifestFile = file("${buildDir}/exploded-bundles/ComGoogleMapsAndroidAndroidMapsUtils03.aar/AndroidManifest.xml")
        if (manifestFile.exists()) {
            println("Replacing minSdkVersion in Android Maps Utils")
            String content = manifestFile.getText('UTF-8')
            content = content.replaceAll(/minSdkVersion="8"/, 'minSdkVersion=\"9\"')
            manifestFile.write(content, 'UTF-8')
            println(content)
        }
    }
}

但是，当我这样做时，我收到无法解析 applicationVariants 的错误。我该如何解决这个问题？

显然，这是一个 Android Studio 错误，告诉我在没有错误的地方有错误。构建和忽略工作正常。
