Intellij Idea Maven'无法重新连接'错误 [英] Intellij Idea Maven 'cannot reconnect' error

问题描述

也许你可以帮助我
当我在Intellij Idea 13打开我的项目时，我遇到了一个奇怪的apache maven的问题。
当项目打开时，我在外部库部分没有库。在diff的模块的所有pom.xml文件中，我看到错误无法重新连接。

Maybe you can help me I got a strange apache maven's problem, when opening my project at Intellij Idea 13. When projects was open I have no libraries at External Libraries section. And at all pom.xml files from diff's modules I see error "Cannot reconnect".

I试图使无效缓存/重启想法无效，尝试使用Maven Reimport，但问题仍然存在。
但是如果我做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。

I tried to Invalidate Cache/Restart Idea, try to use Maven Reimport but problem still take a place. But if I do mvn clean install, and deploy my projects everything works fine. I use Maven 3.2.3. and Java 1.8.

推荐答案

手动删除整个.m2 / repository文件夹，然后向上再次约会您的Maven项目。

Delete the entire .m2/repository folder manually, and then update your Maven project again.
