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 代码中启动一个 Maven 项目，我运行 mvn clean install 命令来生成战争，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：

Please help me!

Answer 1

你确定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

我下载了你的项目并进行了尝试，但我无法重现该问题。它首先按预期停留在“导入项目”上，因为语言服务器正在下载依赖项。然后<1 min, the project "demo" appeared in the explorer.

之后

您可以尝试以下步骤，但我不确定是否可以帮助您。

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.

错误运行命令 spring-boot-dashboard.refresh：找不到命令“spring-boot-dashboard.refresh”。这可能是由贡献 spring-boot-dashboard.refresh 的扩展引起的。
