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。我尝试在各个地方添加 IPv6 标志无济于事。

请注意，代码会遍历我的网络接口，但仍然只接受 127.0.0.1 连接。

错误本身来自 Gradle 代码的这一部分：

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

我在安装新的 Android Studio 时遇到了非常相似的问题。过去 42 小时用谷歌搜索并尝试各种修复。我很高兴我没有像一些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 正在将消息从 IPv4 套接字发送到 Gradle Java 上的 IPv6 套接字.exe进程！

诊断出问题后，只需通过谷歌搜索即可找到正确答案 - 在这篇文章中：https://superuser.com/questions/453298/how-to-force-java-to-use-ipv4-instead-ipv6

这为我解决了问题。

如果您碰巧在装有 Killer Wireless 1535 的游戏笔记本电脑上编写代码，我建议您在 Killer Command Center 中关闭 Killer Double Shot Pro。这对我有用！！

Answer 3

如日志所示，gradle daemon 监听环回接口（ipv4 和 ipv6）：ipv4/ipv6

17:49:57.523 [INFO] [org.gradle.launcher.daemon.server.DomainRegistryUpdater] Advertising the daemon address to the clients: [73551d2b-fa6b-4f37-8520-8694106b50e7 port:49792, addresses:[/0:0:0:0:0:0:0:1%1, /127.0.0.1]]

错误信息显示，连接来自地址 10.0.0.45，不允许连接：

[org.gradle.messaging.remote.internal.inet.TcpIncomingConnector] Cannot accept connection from remote address /10.0.0.45.

Answer 4

这似乎是一个已知的错误，根据https://code.google.com/p/android/issues/detail?id=82347

它提供了一种适用于某些人的解决方法：

The only workaround for me is to use ipv6 instead of ipv4 : in bin/studio.vmoptions or bin/studio64.vmoptions (depending on if you are in 32 or 64 bits), change the line -Djava.net.preferIPv4Stack=true by -Djava.net.preferIPv6Stack=true

还有一种方法可以将守护进程配置为允许远程连接。

卸载 Killer Control Center 和驱动程序是解决方案。
