IDEA中误将jar包引入

在前后台分离工程中，误将工程下的a包引入到b包，导致启动配置重复错误

[WARN ] Jdk14Logger.java:[87] - Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanDefinitionStoreException: Failed to parse configuration class [com.tymk.backend.TymkBackendApplication]; nested exception is org.springframework.context.annotation.ConflictingBeanDefinitionException: Annotation-specified bean name 'bootConfig' for bean class [com.tymk.third.boot.BootConfig] conflicts with existing, non-compatible bean definition of same name and class [com.tymk.backend.boot.BootConfig]

解决方法：file----project structure           modules-----  dependencies   中找到错引的jar包删掉即可。
