警告: Failed to save history 已解决

记录错误：警告: Failed to save history

第一节早八scala上机课，开始练习，当我敲下var i = 5时，直接报错给我整不会了。错误如下

警告: Failed to save history

解决方式

根据提示java.nio.file.AccessDeniedException: C:\Users\Ywei\.scala_history_jline3报了一个异常访问的错误，程序员的优良传统见红就删，直接打开提示路径C:\Users\Ywei找到.scala开头的文件，删了就行。
后续使用就正常了
不用担心，.scala文件删除后后续会重新生成，该咋用咋用
