Spring Boot Dashboard won't show me App on VSCode

I am trying to launch a maven project in visual studio code, I run the mvn clean install command to generate the war and everything is correct, but in the spring-boot dashboard tab the application does not appear to be able to start it.

This is my maven and java version:

PS C:\Projects\PortalTimbrado> mvn -v
Apache Maven 3.6.2 (40f52333136460af0dc0d7232c0dc0bcf0d9e117; 2019-08-27T10:06:16-05:00)
Maven home: C:\Maven\bin\..
Java version: 1.8.0_251, vendor: Oracle Corporation, runtime: C:\Program Files\Java\jdk1.8.0_251\jre
Default locale: es_MX, platform encoding: Cp1252
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows" 

I have tried with the command mvn spring-boot:run but failed, this is the output:

你确定在 pom.xml 中包含了 Maven 构建插件吗？

```xml
<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

同时请检查你的 pom.xml 中的父项目配置：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.3.3.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

然后尝试执行 mvn spring-boot:run 命令。

<build>
	<plugins>
		<plugin>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-maven-plugin</artifactId>
		</plugin>

	</plugins>
</build>

<parent>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-parent</artifactId>
	<version>2.3.3.RELEASE</version>
	<relativePath/> <!-- lookup parent from repository -->
</parent>

我下载了你的项目并尝试了一下，但我无法复现这个问题。一开始它在“导入项目”时卡住了，因为语言服务器正在下载依赖项。大约不到 1 分钟后，“demo” 项目就出现在资源管理器中了。

你可以尝试以下步骤，但我不确定是否能帮助解决你的问题：

- 关闭所有的 VSCode 窗口。
- 打开 ~/.vscode/extensions 文件夹，并删除文件夹名称以 "redhat.java"、"vscjava.vscode-spring-boot-dashboard"、"vscjava.vscode-java-debug"、"pivotal.vscode-spring-boot" 为前缀的文件夹。
- 打开 VSCode，从市场安装 Spring Boot 仪表板扩展。
- 现在尝试再次打开项目，看看是否正常工作。

Close all your VSCode windows.
Open ~/.vscode/extensions folder, and remove folders with prefix like "redhat.java", "vscjava.vscode-spring-boot-dashboard", "vscjava.vscode-java-debug", "pivotal.vscode-spring-boot".
Open VSCode, install the spring boot dashboard extension from the marketplace.
Now try opening the project again, see if it works.
