Maven网络问题？

Question

问题是:Nexus存储库-index.zip下载速度为10 10kbps，maven eclipse:eclipse工件下载停止/暂停。我不是代理的幕后黑手。

编辑：这是由AVG扫描仪引起的，与Maven failing to download jar dependencies中的问题相同

我想我的maven安装/网络连接有一些严重的问题。

以下是我所做的和得到的：

1. 我一直在尝试使用m2eclipse，但是经过一段时间的超时之后，通过eclipse下载了文件 http://mirrors.ibiblio.org/pub/mirrors/maven2/dot-index/nexus-maven-repository-index.zip。我尝试通过wget获取文件，我看到的是下载的速度是11 11kbps。这是某种政策吗？在这个11 11kbps的速度下，它看起来相当稳定。我已经有了一个星期惊人的速度，所以这不是一个暂时的问题。如果这是对每个人来说都是正常的政策和速度-好的。我不使用m2eclipse，没有任何problem.
2. I've放弃使用m2eclipse，我使用的是maven-eclipse插件。不，等等-我没有。下面是当我调用mvn eclipse:eclipse:
3. The工件下载挂起一段时间后，随机发生的情况。然后，我点击^C，再次运行命令，donwload继续，然后再次挂起，有时在相同的工件，有时我得到一个很小的一步。我在调试模式下运行了mvn，它总是挂在相同的位置，下面是堆栈跟踪。英国回购也是如此。

到底怎么回事？谢谢你的帮助，我完全迷路了。我想我的互联网连接是一团糟，但它的工作真的很好(除了maven)。我觉得我被美文回购公司搞得晕头转向。

有什么想法吗？

重要的细节如下：

下面是我如何运行maven (使用相同的线程号)

mvnDebug eclipse:eclipse -DdownloadSources=true -Dmaven.artifact.threads=1

下面是我的maven版本(最新的maven 2版本也是如此)：

$ mvn --version

下面是maven eclipse:eclipse挂起的堆栈跟踪(看起来像是网络问题，但为什么？)：

两条简短的建议：

• 不使用it，规范的Maven存储库是http://repo1.maven.org/maven2 --它由Sonatype维护，现在由全局CDN提供服务。您不应该有任何速度问题，下载index.
• Consider，在您和公共存储库之间放置一个存储库管理器。你经常会发现性能会因此而提高.值得注意的是，

不要费心用wget下载，它不会帮你的。事实上，您可能会看到下载时间较慢，因为您正在尝试使用wget。我最强烈的建议是使用存储库管理器: Nexus或Artifactory。
