891.【java】修复：java: Error during

一、背景

今天在本地调试一个刚接触的代码工程时，遇到如下错误：

java: Error during the transformation of 'com.aicloud.data.util.ExcelUtils'; post-compiler 'lombok.bytecode.SneakyThrowsRemover' caused an exception: java.lang.IllegalArgumentException: Unsupported class file major version 63

这是由于java版本太高了导致的。

二、解决办法

依次点击【File】、【Settings】、【Build,Ex....】、【Compiler】、【Java Compiler】

然后，将报错所在项目的java版本降低。

再次启动代码工程时，就会看不到错误了。
