Maven网络问题？

Question

问题是: Nexus-maven-repository-index.zip 下载速度为 10kbps 和 maven eclipse:eclipse artifact 下载停止/​​暂停。我不支持任何代理。

编辑:这是由 引起的AVG 链接扫描仪 ，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。

这是我所做的和我得到的:

我一直在尝试使用 m2eclipse，但是 下载文件 http://mirrors.ibiblio.org/pub/mirrors/maven2/dot-index/nexus-maven-repository-index.zip经过一段时间的超时后通过 eclipse 。我尝试通过 wget 获取文件，我看到的是下载 速度为 11kbps .这是某种政策吗？在这个 11kbps 上看起来相当稳定。一个星期以来我的速度如此惊人，所以这不是暂时的问题。如果这是每个人的政策和正常速度 - 很好。我不会使用 m2eclipse，没问题。

我已经放弃使用 m2eclipse，我正在使用 maven-eclipse-plugin。不，等等——我不是。以下是我调用 mvn eclipse:eclipse:

时发生的情况

神器一段时间后下载挂起，随机 .然后我点击 ^C，再次运行命令，下载恢复，然后再次挂起，有时在同一个 Artifact 上，有时我会更进一步。我在 Debug模式下运行 mvn ，它总是卡在同一个地方，下面的堆栈跟踪。与英国 repo 相同。

这是怎么回事？感谢您的帮助，我完全迷路了。我假设我的互联网连接一团糟，但它工作得非常好(除了 maven)。我觉得被 maven repo 屏蔽了。

有任何想法吗？

重要细节如下:

这是我运行 maven 的方式(任何线程数都会发生相同的情况)
mvnDebug eclipse:eclipse -DdownloadSources=true -Dmaven.artifact.threads=1

这是我的 maven 版本(最新的 maven 2 版本也是如此):

$ mvn --version
Apache Maven 3.0.4 (r1232337; 2012-01-17 09:44:56+0100)

这是 maven eclipse:eclipse 挂起的堆栈跟踪(看起来像网络问题，但为什么？):

两条快速建议:

不要使用 ibiblio，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。您不应该在下载索引时遇到任何速度问题。

考虑在您和公共(public)存储库之间放置一个存储库管理器。您经常会发现性能会因此而提高……非常显着。

不要费心用 wget 下载，它对你没有帮助。事实上，您可能会看到下载时间变慢，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。
