我们有一个扩展另一个类的类，并继承了一些字段。
在maven中clean install工作正常，并且正在生成impl映射器类。
有时候其他人（学生等）改变了地图制作者，我注意到InteliJ中的build/make project正在破坏。
我收到一个错误，例如以下的堆栈跟踪：

那么，我需要对InteliJ进行某种类型的配置更改吗？
现在对我有用的是转到Spring Boot Run Configuration和Before Launch: Activate tool window部分我做了改变。
我已删除Build Project。因此使用从maven生成的target directory。 Inteli J make命令仅用于重建和热交换更改的类。
