奇怪的java.net.SocketException在Intellij IDEA中运行Groovy时,Permission Denied连接错误

Question

当从IntelliJ IDEA中运行非常简单的URL抓取脚本时,我得到:

java.net.SocketException: Permission denied: connect

但是当我从Groovy控制台运行它时,它运行正常.

这是完整的脚本:

def data = new URL("http://wisc.edu").getText()

这是IntelliJ的完整控制台输出:

我完全不知道是什么导致了这个问题,但我的猜测是,当它运行groovy代码时,IDEA正在做的事情使它无法访问网络.

还有其他人经历过这个吗？有没有人知道一个解决方法？

Answer 1

JDK 1.7中存在与IPv6相关的已知错误.

添加-Djava.net.preferIPv4Stack=true在VM选项应该可以解决问题.
