【问题描述】：
也许你可以帮助我 在 Intellij Idea 13 打开我的项目时，我遇到了一个奇怪的 apache maven 问题。 当项目打开时，我在外部库部分没有库。在所有来自 diff 模块的 pom.xml 文件中，我看到错误“无法重新连接”。
我试图使缓存/重启想法无效，尝试使用 Maven 重新导入，但问题仍然存在。 但是，如果我执行 mvn clean install 并部署我的项目，一切正常。 我使用 Maven 3.2.3。和 Java 1.8。
Maven 设置：
添加了idea.log文件：

我的猜测是你的 IntelliJ Maven 插件有问题，但是从命令行运行 Maven 没有问题。
-
@TimBiegeleisen - 您可以右键单击并在新选项卡中打开它。它足够大。 @MeetJoeBlack - 请检查
idea.log并查看那里存在哪些错误详细信息。 -
您是否尝试过使用捆绑的 Maven 而不是命令行？ puu.sh/iaG9U/bd94fce2ba.png

我的问题已通过更新 /etc/hosts 文件解决。 Refer this
