找不到 Spring Boot IntelliJ

Question

我正在努力使我的设置能够运行 Intellij + SpringBoot。 我从 spring initializr 下载了一个常规的 pom.xml。 当我构建/运行项目时，它没有找到 spring boot 依赖项，但运行 mvnw spring-boot:run 工作正常。 所以我认为这可能与 IntelliJ 有关，但根本无法弄清楚。 注意：这是所有内容的全新安装。并使用

openjdk 版本“1.8.0_252”OpenJDK 运行环境 (AdoptOpenJDK)(build 1.8.0_252-b09) OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.252-b09, 混合模式)

我的 Maven 设置是默认设置

我在逃避什么吗？ BR

Answer 1

尝试在 intellij IDEA 中安装 lombok：

1. 转到文件 > 设置 > 插件。
2. 点击浏览存储库...
3. 搜索 Lombok 插件。
4. 点击安装插件。
5. 重启 IntelliJ IDEA。

如果还是不行，试试： File->Invalidate cache and restart 然后构建你的项目。 希望这会有所帮助。
