通过wget的http://repo.maven.apache.org它没有显示任何错误。任何人都可以帮助我吗？

我想运行YCSB基准，我得到了这个错误。

它在最后显示错误。插件org.apache.maven.plugins：maven-clean-plugin：2.4.1或其某个依赖项无法解析：无法读取工件。下载maven的新副本并将其配置为环境变量，然后重试。也用pom.xml更新您的文章 –

由于错误说，你是不是能够连接到Maven仓库在：http://repo.maven.apache.org

尝试不同的存储库，details here或添加到您的POM，这样的：

<repository>    
      <id>central</id> 
      <name>Central</name> 
      <url>http://repo1.maven.org/maven2</url> 
</repository>

已添加pom.xml代码您可以检查它..感谢您的即时回复 – Rohit

@Rohit您可能需要更改maven seetings.xml以配置te存储库。 settings.xml位于$ {user.home} /。m2/settings.xml下。按照此链接了解该文件，并知道如何配置存储库：http://maven.apache.org/settings.html –

Thanx我明白了...代理问题 – Rohit

可以有2种可能性。

您遇到了连接中央存储库的问题。
有些事情不对在你的pom.xml

例外说，这个问题是不是在YCSB但在连接尝试下载Maven的清洁插件库中。

所以，在这里发送pom.xml，以防万一检查你的网络连接，然后再试一次。是否有机会通过使用代理的浏览器访问互联网，而maven直接进行，因此连接不可用？或者公司的防火墙检查用户代理并且不允许你连接到存储库？

编辑：

BTW似乎版本2.4.1不是在库中。至少可以手动查看1.0版本，1.0版本和1.5版本

这可能会发生，如果你在代理的后面，请添加代理设置~/.m2/settings.xml并尝试。

例子：

<proxies> 
    <proxy> 
     <active>true</active> 
     <protocol>http</protocol> 
     <host>proxy host name</host> 
     <port>port</port> 
     <username>username</username> 
     <password>password</password> 
     <nonProxyHosts>exclutions</nonProxyHosts> 
    </proxy> 
</proxies>

看起来像你的Maven无法连接到定义为拉动所需的构件库。你是否支持代理？在这种情况下，您需要在maven-conf-settings.xml中配置代理设置。
