java - Spring Boot 仪表板不会在 VSCode 上显示应用程序

Question

我正在尝试在 Visual Studio 代码中启动 Maven 项目，我运行 mvn clean install 命令来生成 war ，一切都正确，但在 spring-boot 仪表板选项卡中，应用程序似乎无法启动它。

这是我的 Maven 和 java 版本:

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" 

我尝试使用命令mvn spring-boot:run但失败了，这是输出:

您确定 pom.xml 中有 Maven 构建插件吗

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

    </plugins>
</build>

还要检查 pom.xml 中的父级

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

然后重试mvn spring-boot:run命令
