Idea中提示错误信息：Usage of API documented as @since 1.6+ less...

最近在Idea中遇到这么一个错误提示信息：

Usage of API documented as @since 1.6+ less... (Ctrl+F1)

This inspection finds all usages of methods that have @since tag in their documentation.

This may be useful when development is performed under newer SDK version as the target platform for production.

原因：意思是说明我们的项目配置的language level不够，去修改下就可以了

解决：打开Project Structure --》 Modules --》 Language Level 选择高版本的即可

 

如果idea的编译器提示错误消失，启动项目代码后发现此错误：

Information:Using javac 1.8.0_40 to compile java sources
Information:java: javacTask: 源发行版 1.8 需要目标发行版 1.8
Information:java: Errors occurred while compiling module 'provider'
Information:Module "provider" was fully rebuilt due to project configuration/dependencies changes
Information:2019/7/18 11:43 - Compilation completed with 1 error and 0 warnings in 2s 109ms
Error:java: Compilation failed: internal java compiler error

一般需要核查三个地方是否一致，我这里用的jdk版本是1.8，需要核查以下三个地方：

1，第一个就是上面所提到的Language Level

2，第二个是

3，第三个是

保持都一致，就解决了该问题。
