Question

Answer 1

根据您使用的Java 8功能， Retrolambda可以提供帮助（在此处复制整个自述文件毫无意义）。

Answer 2

You should change your project compile level to 6 and re-build,if you don't use any Java 8 features.

In intellij, press F4 on your Project, then on Project Settings page, click Project , modify Project language level to 6 @Override in interfaces .

Hope this can help you!
