我们决定将对 Java 8 语言功能的支持直接添加到当前的 javac 和 dx 工具集中，并弃用 Jack 工具链.有了这个新的方向，依赖于 Java 类文件格式的现有工具和插件应该可以继续工作.展望未来，Android 构建系统将原生支持 Java 8 语言功能.我们的目标是在未来几周内将其作为 Android Studio 的一部分推出，我们希望尽早与您分享这一决定.

We've decided to add support for Java 8 language features directly into the current javac and dx set of tools, and deprecate the Jack toolchain. With this new direction, existing tools and plugins dependent on the Java class file format should continue to work. Moving forward, Java 8 language features will be natively supported by the Android build system. We're aiming to launch this as part of Android Studio in the coming weeks, and we wanted to share this decision early with you.
