mvn 无法安装 Jetty

Question

我的 pom 文件：

      </plugin>
    </plugins>
  </build>
</project>

当我做 mvn jetty:run 时，我收到错误消息说找不到 jetty。我手动检查了 urls.They 似乎 valid.Also 我尝试了很多很多 versions.All 失败，同样 error.Can 我手动配置 jetty？或者我们可以使用其他服务器吗？

您的插件定义不正确 <artifactId>。

改用正确的：

  <plugin>
    <groupId>org.eclipse.jetty</groupId>
    <artifactId>jetty-maven-plugin</artifactId>
    <version>9.4.5.v20170502</version>
  </plugin>
