Question

我创建了一个带有SpringBoot的项目，项目包装类型为jar，并且我将码头依赖项添加到了项目中，当我尝试使用mvn jetty:run构建项目时，构建成功但我收到这样的消息

[INFO]跳过keycloak-springboot-demo：包装类型[jar]为不支持

下面是我的pom.xml文件

如何使用jetty：run命令在jetty服务器中运行项目？

Answer 1

我在9.4.19.v20190610上遇到了同样的问题。我必须添加：

<supportedPackagings>jar</supportedPackagings>

Answer 2

jetty-maven-plugin将部署打包为war（网络存档）文件的Web应用。

您的项目被指定为<packaging>jar</packaging>，这意味着Jetty不知道如何部署它（什么是Web清单？描述符？libs？资源库？它在哪里扫描字节码以获取servlet注释和功能？等）< / p>

您的spring-boot用法似乎是基于spring-boot本身的独立嵌入式码头用法。在这种设置中使用jetty-maven-plugin是不合适的。

Answer 3

尝试将Jetty版本更改为 9.3.27.v20190418

这对我有用

<plugin>
    <groupId>org.eclipse.jetty</groupId>
    <artifactId>jetty-maven-plugin</artifactId>
    <version>9.3.27.v20190418</version>
    <configuration>
      <httpConnector>
        <port>8080</port>
      </httpConnector>
      <scanIntervalSeconds>-1</scanIntervalSeconds>
      <reload>manual</reload>
      <useTestScope>true</useTestScope>
      <webAppConfig>
        <resourceBase>src/test/webjar-debug/META-INF/resources</resourceBase>
        <resourceBase>${project.basedir}/src/main/resources/META-INF/resources</resourceBase>
      </webAppConfig>
    </configuration>
</plugin>

我尝试使用版本 9.4.X ，但没有效果
