无法在IntelliJ中编译/运行Java项目

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，以模拟当前项目中发生的相同问题.

While it was working fine yesterday. Today, I wasn't able to compile my project(spring-boot). I created a demo project to simulate the same issue that happened in my current project.

当我尝试使用运行按钮运行项目时，它不想编译.注意失败的编译中的所有错误.此外，您还可以看到所有依赖项均已导入(请参见外部库):

When I try to run the project using the run button It doesn't want to compile. Note all the errors from the failed compilation. Also, you can see that all dependencies are imported (see External Libraries):

我知道我可以通过在终端中键入 mvn spring-boot:run 来运行该应用程序.但是出于某种原因，我不想这样做.

I know I can run the app by typing mvn spring-boot:run in the terminal. But for some reason, I don't want to do that.

如您所见，此演示是一个简单的spring-boot项目:

As you can see, this demo is a simple spring-boot project:

pom.xml:

我尝试了无数种解决方案:

I've tried countless solutions among them:

• 选择构建->重建项目
• 点击文件>使缓存无效/重启
• mvn clean -> Build-> Make Project
• Maven->重新导入
• 删除了 .iml 文件并重新导入了项目
• 检查了首选项中是否存在排除项|构建，执行，部署|编译器排除

• Select Build->Rebuild Project
• Clicking File>Invalidate caches/ restart
• mvn clean -> Build -> Make Project
• Maven -> Reimport
• Deleted .iml file and re-imported the project
• Checked that there is no excludes in Preferences | Build, Execution, Deployment | Compiler | Excludes

我在这个问题上花了很多时间.我该如何解决?

I've spent lots of time on this issue. How can I fix it?

运行 mvn全新安装-X :
