Maven網絡問題？

Question

問題是：Nexus-maven-repository-index.zip在10kbps和maven eclipse下載：eclipse神器下載停止/​​暫停。我不支持任何代理。

編輯：這是由AVG鏈接掃描儀，相同的問題引起的，如Maven failing to download jar dependencies

我想我已經得到了一些嚴重的問題，與我的Maven安裝/網絡連接。

這就是我做什麼，我得到：

1. 我一直在試圖使用m2eclipse的，但一段時間超時後通過Eclipse下載文件http://mirrors.ibiblio.org/pub/mirrors/maven2/dot-index/nexus-maven-repository-index.zip。我試圖通過wget獲取文件，我看到的是，下載速度爲11kbps。這是一種政策嗎？這個11kbps看起來很穩定。現在我已經有了如此驚人的速度，所以這不是一個暫時的問題。如果這是每個人的政策和正常速度 - 那很好。我不會使用m2eclipse，沒問題。

2. 我已經辭職了使用m2eclipse，我使用的是maven-eclipse-plugin。不，等等 - 我不是。以下是我在調用mvn eclipse時會發生的事情：eclipse：

3. 神器下載後暫時掛起，隨機。然後，我擊中^ C，再次運行命令，donwload恢復，然後再次掛起，有時在相同的神器上，有時我會進一步進一步。我在調試模式下運行mvn，它總是掛在同一個地方，下面的堆棧跟蹤。跟英國回購一樣。

發生了什麼事？感謝任何幫助，我完全失去了。我假設我的互聯網連接是混亂的，但它工作得很好（除了maven）。我覺得像maven repo blakclisted。

任何想法？

重要細節如下：

下面是如何運行Maven（與任何線程的數目同樣的情況）

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

這裏是我的Maven版本（同樣的情況與最新maven 2版）：

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

這裏的堆棧跟蹤，其中行家日食：（？看起來像一個網絡問題，但爲什麼）蝕掛起：

Answer 1

兩個快速條建議：

• 不要使用ibiblio上，規範Maven倉庫爲http://repo1.maven.org/maven2 - 它是由Sonatype的維護，它現在擔任過全球CDN的。下載索引時不應有任何速度問題。

• 請考慮在您和公共存儲庫之間放置存儲庫管理器。你會經常發現性能會因此而提高......非常顯着。

不要打擾使用wget下載，它不會幫助你。實際上，您可能會看到較慢的下載時間，因爲您正嘗試使用wget。我最強烈的建議是使用存儲庫管理器：Nexus或Artifactory。
