无法在maven项目下使用jar打包构建maven模块。。。！

我无法使用jar打包构建maven maodule。我得到的错误是

Could not calculate build plan: Failure to transfer org.apache.maven.plugins:maven-resources-plugin:pom:2.4.3 from http://repo1.maven.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.apache.maven.plugins:maven-resources-plugin:pom:2.4.3 from/to central (http://repo1.maven.org/maven2): ConnectException

我的机器被标记到公司网络，他们有代理问题吗？我尝试使用以下内容创建settings.xml：

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      http://maven.apache.org/xsd/settings-1.0.0.xsd">
  <localRepository>${user.home}/.m2/repository</localRepository>
  <interactiveMode>true</interactiveMode>
  <usePluginRegistry>false</usePluginRegistry>
  <offline>false</offline>
  <pluginGroups/>
  <servers/>
  <mirrors/>
  <proxies>
    <!-- proxy
     | Specification for one proxy, to be used in connecting to the network.
     |-->
    <proxy>
      <id>optional</id>
      <active>true</active>
      <protocol>http</protocol>      
      <host>proxy.tcs.com</host>
      <port>80</port>
      <nonProxyHosts>localhost|google.com</nonProxyHosts>
    </proxy>

  </proxies>
  <profiles/>
  <activeProfiles/>
</settings>

我已经配置了Maven链接

http://m2eclipse.sonatype.org/sites/m2e

使用eclipse版本Juno和Jdk 1.7。

我尝试了网络上所有可能的解决方案，但没有成功。

问题在于代理设置，因为我们在公司使用代理网络，Maven无法正确下载其插件，所以添加了带有代理设置的settings.xml文件，效果很好。

你有权访问吗？没有，当我点击url时，它的意思是：浏览此目录已被禁用。改为在上查看此目录的内容。如果公司阻止了上述链接，则会显示为公司阻止了该网站。对不起，您可以浏览此链接吗：因此，您可以尝试在C:\Users\346496\.m2\repository\org\apache\maven\plugins\maven resources plugin\中清除本地repo，删除内容可能会解决您的问题
