Android，Gradle : RetroLambda不工作

Question

我正在开发一个安卓应用程序，我想出了一个RetroLambda工具，通过它我可以在安卓应用程序中使用Lambda表达式(太棒了！！)

不幸的是，它不起作用。我正在为应用程序和整体发布我的Gradle文件。请让我知道我做错了什么。非常感谢。

我现在正在Emulator中运行。我希望这不是问题所在。非常感谢。

Answer 1

你可以看看我的项目。我使用的是retrolambda。但是要构建项目，您需要在系统上定义java8路径。https://github.com/JenyaKirmiza/GithubClient

Answer 2

您可以在应用程序的build.gradle (而不是根项目)中应用该插件。你应该检查的另一件事是，你的依赖是否有java8编写的类。如果是这样，请注意该插件只适用于您当前的项目(类)，与依赖项中的类无关。如果你想对这些依赖项进行retrolambda，你可以在某个地方解压它们，然后在上面应用插件。
