Spring boot 2 lombok:jar:2.6.7 丢失，没有可用的依赖信息

Question

这是我pom.xml从 start.spring.io 生成的 M2 spring-boot 版本。这就是添加 maven spring 存储库的原因。但是找不到依赖项。

我从 start.spring.io 下载了一个类似的 spring 项目 - 2.2.0.M2，具有类似的依赖项。下面是我的 pom.xml 文件<modelVersion>4.0.0</modelVersion><parent>&nbsp; &nbsp; <groupId>org.springframework.boot</groupId>&nbsp; &nbsp; <artifactId>spring-boot-starter-parent</artifactId>&nbsp;
