尝试使用JDK 1.8和
eclipse neon构建项目时出现以下错误：

我需要更改哪些项目设置才能修复它们？
解决方法
你必须告诉你的java编译器生成java 7兼容的类文件,因为android(dex)目前不支持java 8.
如果你想在你的资源中使用lambdas,你可以使用retrolambda(https://github.com/evant/gradle-retrolambda)或新的Jack编译器(https://developer.android.com/preview/j8-jack.html)
更新：从Android Studio 3.0和Android Gradle Plugin 3.0开始,也可以使用java 8类文件.
