为什么jackOptions不能在Android Studio 2.2 Preview 1中使用呢?

I went through the guide to add:

我浏览了一下指南，补充道:

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

defaultConfig {
    jackOptions {
        enabled true
    }
}

To my android section of my module's build.gradle file. I also set the gradle plugin version to 2.2.0-alpha1 and even tried gradle wrapper 2.13.

到我模块构建的android部分。gradle文件。我还将gradle插件版本设置为2.2.0-alpha1，甚至尝试过gradle包装2.13。

When I try to compile, I get:

当我试图编译时，我得到:

Error(105, 0): Gradle DSL method not found: jackOptions()

I also tried commenting out jackOptions and using "useJack true", which compiled and created an APK, but I had no classes.dex file.

我还尝试过注释jackOptions并使用“useJack true”，它编译并创建了一个APK，但是我没有class .dex文件。

Why am I getting this error about jackOptions? What am I missing here?

为什么会有这个关于jackOptions的错误?我错过了什么?
