英文:
error: "A project with the name X already exists" (Java/Maven/VScode)
问题
我正在按照这个VScode教程的指示进行操作：https://code.visualstudio.com/docs/java/java-webapp。它基于Spring Boot的这个教程：https://github.com/spring-guides/gs-spring-boot
我现在在构建项目的步骤。我打开complete/bin/src中的Application.java文件，然后按下F5进行构建。但每次都会遇到以下错误：
"已经存在一个名为spring-boot的项目。
提供的分阶段操作由于异常而失败。
重复的根元素spring-boot"
在VScode资源管理器的'Maven'选项卡中，确实显示了两个名为"spring-boot"的项目。我认为这可能是因为'initial'文件夹中也有一个Maven项目。我尝试删除了这个'initial'文件夹，但错误仍然存在。
这是我第一次构建Web应用，也是第一次使用Maven、VSCode和Spring Boot。而且，我的问题可能与Spring Boot/Maven/VSCode的组合有关。

I'm following the instructions in this VScode tutorial: https://code.visualstudio.com/docs/java/java-webapp. It is based on this tutorial by Spring Boot: https://github.com/spring-guides/gs-spring-boot
I'm at the step of building the project. I open the Application.java file in complete/bin/src and press F5 to build. I get this error every time:
"A project with the name spring-boot already exists.
The supplied phased action failed with an exception.
Duplicate root element spring-boot"
The 'Maven' tab of VScode's explorer does show two projects titled "spring-boot". I think this is because there is also a maven project in the "initial" folder. I tried deleting this "initial" folder but the error persisted.
This is my first time building a web app, and first time using Maven, VSCode, and Spring Boot. Also, my question might be specific to the combo of Spring Boot/Maven/VScode.
Here is a screenshot of my the VScode project, showing all the elements discussed here: https://i.stack.imgur.com/d1zY3.jpg

以下是我解决相同问题的方法。
该存储库包含两个项目：initial（初始）和complete（完成）。要按照教程进行操作：
-
删除“complete”项目；你应该删除主机上存储它的“complete”文件夹，并重新启动VS Code以查看更改。
-
如果像我遇到的情况一样，在VS Code中无法直接删除它，你也可以尝试以同样的方式删除“initial”文件夹。这对我起作用了。

Here's how I solved the same issue.
The repository contains two projects: initial and complete. To follow the tutorial:
-
Delete the "complete" project; you should delete the "complete" folder where you stored it on your host and restart VS-code to see the changes.
-
In case, like happened to me, you are unable to delete it in VS code directly, you can also try deleting the "initial" folder that way. It worked for me.
