Gradle新手。如果这是一个糟糕的问题，我深表歉意。
我一直在尝试启动一个简单的Java8Gradle项目。一切都很好，直到我尝试将龙目添加到我的项目中。
我的Intellij IDE具有Lombok所需的所有设置。
- Lombok插件已安装并激活
- 注释处理器已打开
IDE完美地处理了注释。没有显示错误，并且样板显示在代码结构中。
然而，当我尝试使用Intellij构建项目或运行主方法时，编译器会抱怨Lombok应该生成的样板文件不存在。

即使您不想使用spring，也可以在https://start.spring.io/并选择Gradle并添加Lombok依赖项。它将在适当的配置(包括annotationProcessor(中使用Lombok为您创建一个build.gradle
