Java 解析插件的版本时出错'；jetty:jetty maven插件'；

我使用的是apache-maven-3.0.5，出现以下错误：

解析插件“org.mortbay.jetty:jetty maven plugin”的版本时出错 从存储库[本地（C:\Documents and Settings\lamiranda.m2\repository）， 瓦丁快照（）， 中央的(http://repo.maven.apache.org/maven2)]：在任何插件存储库中都找不到插件

当我执行“作为Maven clean运行”或“作为Maven安装运行”时，会发生以下错误：

你能帮我吗？

在pom.xml中添加以下代码片段

<project ...>
<repositories>
    <repository>
      <id>maven repo</id>
      <url>http://repo1.maven.org/maven2/</url>
    </repository>
 </repositories>
</project>

马文回购
http://repo1.maven.org/maven2/

注意：

标记正好代表

如果要下载的存储库中不存在它，请检查它试图下载的版本，然后检查您的网络设置

看起来像是网络连接故障。 插件URL： 有空。

检查构建时是否在线。

是否在防火墙或代理后运行？运行maven命令时，添加

-X

以输出更详细的消息。它可能对我有帮助，但我添加了maven repo repo1.maven.org/maven2/
