項目構建總是報錯：

錯誤提示1：java:重復類

或

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

排查發現build/generated/sources/annotationProcessor路徑下會生成2個同名類導致，

IDEA和Gradle會各自構建生成文件造成沖突。

（起初以為是mapstruct與lombok沖突導致，后附mapstruct與lombok的引入配置）

解決方案：

IDEA-》設置-》構建、執行、部署-》構建工具-》Gradle

使用此工具構建/運行：IntelliJ IDEA

使用此工具運行測試：IntelliJ IDEA

Clean后再重新構建即可

Jdk17+Spring boot 3.3.13+Gradle
