那些遇到过的问题

无法在 IntelliJ 中编译/运行 Java 项目

ham*_*uki 3 java intellij-idea maven spring-boot

问题：

虽然昨天工作正常。今天，我无法编译我的项目（spring-boot）。我创建了一个演示项目来模拟我当前项目中发生的相同问题。

当我尝试使用运行按钮运行项目时，它不想编译。请注意失败编译中的所有错误。此外，您可以看到所有依赖项都已导入（请参阅外部库）：

在此处输入图片说明

我知道我可以通过mvn spring-boot:run在终端中输入来运行该应用程序。但出于某种原因，我不想那样做。

可以看到，这个demo是一个简单的spring-boot项目：

我试过的：

我尝试了无数的解决方案：

  • 选择Build->Rebuild Project
  • 单击文件>使缓存无效/重新启动
  • mvn clean->构建 -> 制作项目
  • Maven -> 重新导入
  • 删除.iml文件并重新导入项目
  • 检查首选项中没有排除项| 构建、执行、部署 | 编译器 | 不包括

我在这个问题上花了很多时间。我该如何解决？

感谢安德里的评论，我的问题得到了解决。以下是我所做的步骤：

  1. 导出 IDE 设置（键盘映射、插件）。您可以通过转到文件 |导出它。管理 IDE 设置 | 导出设置...它将导出一个 zip 文件，您可以稍后在恢复默认 IDE 配置时将其导入
  2. 转到文件 | 管理 IDE 设置 | 恢复默认设置... IDE 将重新启动并恢复到默认配置。此命令重新生成path.macros.xml了缺少正确配置的文件。请注意，您可以在<IDE config>/options目录中归档
  3. 导入导出的 zip 文件File | 管理 IDE 设置 | 导入设置...

  • 不幸的是它没有帮助我解决同样的问题 (3认同)
  • 这是新的“无效缓存并重新启动”=)) (2认同)
