【问题描述】：
我创建了一个非常简单的默认应用程序，用于在我的 Windows 7 机器上测试我的 Eclipse Indigo/Maven v3.0.1 设置。 Hello World 应用在 Eclipse 中运行良好。
现在，我尝试在命令行中使用mvn install 进行测试。
此时我看到 Maven 下载了大量依赖项。出于某种原因，虽然它会在下载一个时卡住，并且会在中途停止。每次都不在同一点，但目前始终是同一个jar文件，例如...
http://repo1.maven.org/maven2/org/apache/maven/surefire/surefire-booter/2.5/surefire-booter-2.5.jar
如果我从浏览器下载此文件，它可以完美运行。事实上相当快。现在，如果我手动将该下载的文件复制到我的 .m2 存储库目录中的相应目录，安装将继续下载依赖项，直到它随机遇到另一个并停止。
这是我的 POM，虽然我不确定它是否会有所帮助，因为它非常基础，而且似乎可以与 mvn compile 一起使用。

这是一些引用一些虚拟 jar 文件的调试输出？

【问题讨论】：
-
Maven 日志会很有用...而且 Maven 应该在下载失败时重试（至少在校验和失败时）。
-
首先，如果您从命令行更新到最新版本的 maven (3.0.3)
-
您是否尝试过使用上述存储库以外的其他存储库？
-
此外，这听起来像是网络问题....
-
糟糕。点击进入太快了。我不确定这是校验和错误，但如果我没有找到解决方法，我会登录。我找到了“一个”解决方案。我在我的 settings.xml 文件中添加了一个镜像以指向mirrors.ibiblio.org/pub/mirrors/maven2，它第一次工作。我现在也将升级到 3.0.3，看看是否可以修复它。谢谢大家！
