项目构建总是报错：

错误提示1：java:重复类

或

错误提示2：Internal error in the mapping processor: java.lang.RuntimeException: javax.annotation.processing.FilerException: Attempt to recreate a file

排查发现build/generated/sources/annotationProcessor路径下会生成2个同名类导致，

IDEA和Gradle会各自构建生成文件造成冲突。

（起初以为是mapstruct与lombok冲突导致，后附mapstruct与lombok的引入配置）

解决方案：

IDEA-》设置-》构建、执行、部署-》构建工具-》Gradle

使用此工具构建/运行：IntelliJ IDEA

使用此工具运行测试：IntelliJ IDEA

Clean后再重新构建即可

环境：

Jdk17+Spring boot 3.3.13+Gradle
