在 Intellij IDEA 中运行 Groovy 时，奇怪的 java.net.SocketException Permission Denied 连接错误 [英] Weird java.net.SocketException Permission Denied connect error when running Groovy in Intellij IDEA

问题描述

在 IntelliJ IDEA 中运行 非常 简单的 URL 抓取脚本时，我得到:

java.net.SocketException:权限被拒绝:连接

但是当我从 Groovy 控制台运行它时，它工作得很好.

这里是完整的脚本:

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

这里是 IntelliJ 的完整控制台输出:

我完全不知道是什么导致了问题，但我的猜测是IDEA在运行groovy代码时正在做的事情，使其无法访问网络.>

有没有其他人遇到过这种情况?有人知道解决方法吗?

解决方案

有一个已知错误.

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

When running a VERY simple URL grab script from within IntelliJ IDEA, I get:

java.net.SocketException: Permission denied: connect

but when I run it from the Groovy Console, it works just fine.

Here is the full script:

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

and here is the full console output from IntelliJ:

I have absolutely no idea what is causing the problem, but my guess is that it's something IDEA is doing when it runs the groovy code that keeps it from being able to access the network.

Has anyone else experienced this? Does anyone know of a workaround?

解决方案

There is a known bug in JDK 1.7 related to IPv6.

Adding -Djava.net.preferIPv4Stack=true in VM Options should fix the problem.
