问题描述

我正在使用Eclipse开发Spring MVC.直到现在，我还使用ant来创建war文件.但是现在我切换到了Maven.我已经在系统上复制了Maven 3.3，并为Maven设置了系统变量.当我从命令提示符运行以下命令时，它运行正常:

I am working on a Spring mvc using Eclipse. Until now I was using ant to create war file. But now I switched to Maven. I have copied Maven 3.3 on my system and set system variables for Maven. It works fine, when I run Maven following command from command prompt:

mvn -version

我已经在Spring mvc应用程序的根目录中创建了pom.xml文件.我通过命令提示符而不是通过Eclipse运行Maven.当我运行以下命令时:

I have created a pom.xml file in my Spring mvc app's root directory. I run Maven through command prompt, not through Eclipse. When I run following command:

mvn -X package

它显示以下错误:

它说连接超时，但是我的互联网运行正常.

It says connection timed out, but my internet is running fine.

推荐答案

我发现设置MAVEN_OPTS环境变量是可行的.显然，JDK7存在一些问题: https://issues.apache.org/jira/browse /MNG-5162

I found that setting my MAVEN_OPTS environment variable worked. Apparently JDK7 has some issues with it: https://issues.apache.org/jira/browse/MNG-5162

export MAVEN_OPTS="-Djava.net.preferIPv4Stack=true"
