mvn 无法安装 Jetty

Question

我的 pom 文件：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

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

当我做mvn jetty:run 时，我收到错误消息说它找不到jetty。我手动检查了网址。它们似乎有效。而且我尝试了很多版本。所有版本都失败并出现相同的错误。我可以配置jetty 手动？或者还有其他我们可以使用的服务器吗？

Answer 1

您的插件定义有一个不正确的<artifactId>。

改用正确的：

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