android - 如何修复 Android Studio 无法连接到 Gradle 守护进程？

Question

我正在尝试启动 Android Studio 并不断收到 Gradle 错误。查看守护程序日志，守护程序似乎只接受来自 IPv6 连接或 127.0.0.1 的连接。

但是，我不知道如何让它接受其他连接或使用 IPv6。我曾尝试在各个地方添加 IPv6 标志，但无济于事。

请注意，代码遍历我的网络接口(interface)，但仍然只接受 127.0.0.1 连接。

错误本身来自这部分 Gradle 代码:

https://code-review.gradle.org/browse/Gradle/subprojects/messaging/src/main/java/org/gradle/messaging/remote/internal/inet/TcpIncomingConnector.java?r=6264564978680860f88e7a43659459f778546fe8#to104

这是日志文件:

Answer 1

我在安装新的 Android Studio 时遇到了非常相似的问题。花了最后 42 小时谷歌搜索并尝试各种修复。我很高兴我没有像一些人建议的那样删除我的防火墙—​​—因为防火墙日志实际上帮助我诊断了这个问题的根本原因——即 Android Studio 正在从 IPv4 套接字向 Gradle Java 上的 IPv6 套接字发送消息.exe进程!

诊断出问题后，通过谷歌搜索正确答案是一个简单的步骤 - 在这篇文章中:https://superuser.com/questions/453298/how-to-force-java-to-use-ipv4-instead-ipv6

这对我来说已经解决了。
