java - Spring Boot 找不到 IntelliJ

Question

我正在努力让我的设置能够在 Intellij + SpringBoot 上运行。 我从 springinitializr 下载了常规的 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。 所以我认为这可能是 IntelliJ 的问题，但就是无法弄清楚。 注意:这是所有内容的全新安装。并使用

openjdk version "1.8.0_252" OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_252-b09) OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.252-b09, mixed mode)

我的 Maven 设置是默认的

我是在逃避什么吗？ BR

Answer 1

尝试在intellij IDEA中安装lombok:

1. 转至"file">“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. 重新启动 IntelliJ IDEA。

如果仍然不起作用，请尝试: 文件->使缓存无效并重新启动，然后构建您的项目。 希望这会有所帮助。
