Gradle: 无法在Windows上连接到Kotlin守护进程

Question

Gradle: 无法在Windows上连接到Kotlin守护进程

windowsgradlekotlincompilationdaemon

27

当我尝试执行涉及compileKotlin（或compileTestKotlin）的任务时，我收到此警告并且构建过程需要很长时间：

无法执行增量编译：无法连接到 Kotlin 编译进程

无法连接到 kotlin 守护程序。使用备用策略。

我不确定问题是否与我的操作系统（Windows）有关，但是我将具有同步文件的相同项目放在另一台具有 Linux 操作系统的远程机器上，那里就不存在这个问题。请参见以下比较：

在我的远程机器上的项目（Linux），其中 Kotlin 源代码有少量更改（在一个模块中）：

$ ./gradlew build

Deprecated Gradle features were used in this build, making it incompatible with Gradle 6.0.
Use '--warning-mode all' to show the individual deprecation warnings.
See https://docs.gradle.org/5.0/userguide/command_line_interface.html#sec:command_line_warnings

BUILD SUCCESSFUL in 5s
46 actionable tasks: 17 executed, 29 up-to-date

同一项目在我本机（Windows）上有相同的更改：

> gradlew build

特别注意上述两个示例中的构建持续时间（以及Windows机器上compileKotlin任务后的警告）。尽管我的本地机器（Windows）具有更强大的硬件，但结果相反（Gradle守护程序在两台机器上都运行）。

为了进一步分析性，我还发布了两台计算机上gradle -v和java -version的输出：

Linux：

$ ./gradlew -v

更新 1:

当Gradle JVM设置为JDK 8时，没有问题。但是在使用JDK 9+时，您会遇到此问题。

更新 2:

我将Kotlin插件从1.3.10升级到1.3.11。同时，测试了1.3.20-eap-52。但问题仍然存在。

更新 3:

我运行了Gradle的compileKotlin任务，并使用--debug选项获取更多信息。输出中最重要的部分如下：

^{注意: 当Gradle守护进程正在运行、Kotlin编译守护进程被停止（如果已经运行）且对Kotlin源文件进行了小幅更改时，已运行以下任务。}

I. 在使用JDK 8作为Gradle JVM时 (正常):

上述日志中有一些可疑事件（第二个日志），但我无法确切理解它们的含义，也不知道它们是否与我的问题有关：

为什么会出现两次（完全相同）尝试来启动 Kotlin编译守护进程？
虽然存在一些错误，但它们都是在 Kotlin 守护程序问题的警告之后出现的。
最新的错误/警告信息:
```
[ERROR] [system.err] warning: the '-d' option with a directory destination is ignored because '-Xbuild-file' is specified
```
最可疑的就是它！因为这是你在其他日志中找不到的唯一消息。另请参见此处。我在另一个帖子中也问了这个问题。

在我的情况下，我通过清除用户文件夹中的一些缓存来解决了问题，特别是：

C:\Users\user\.android\build-cache\
C:\Users\user\.android\cache\
C:\Users\user\.gradle\caches\

不确定哪个起了作用，但在清除所有内容后，错误消失了。

没有帮助。可能无关。 - Ace

已清除第一和第二项，这有所帮助，谢谢。 - mxkmn

我知道这个问题有答案，但当我尝试同样的方法时，项目仍然报了同样的错误：

“无法连接到Kotlin守护进程”

但后来我通过进入Android Studio的终端并运行以下代码解决了这个问题：`.\gradlew --stop`。之后我清理了项目并重新运行，问题得到了解决，我成功下载了应用程序。希望有人看到这个并能解决他们的问题。

- Abood

停止守护进程并停止1个，然后重新构建，大功告成。谢谢。 - undefined

我将kotlin从 ext.kotlin_version = '1.4.32' 降级到 ext.kotlin_version = '1.3.50'，问题已解决。

重启ADB对我来说起作用了。只需在终端上运行以下命令即可：

adb kill-server
adb start-server

最终，经过几天的努力，我找到了问题的源头...

我发现问题来自于我的用户帐户。于是决定将任何与用户相关的内容还原为其最初状态。在清除 AppData\local\ 中的 Temp 文件夹时，我意外地看到了这些文件:

kotlin-daemon.Û²Û°Û±Û¹-Û°Û±-Û°Û¸.Û°Û³-ÛµÛ´-Û±Û²-Û¶Û´Û¸.00.log
kotlin-daemon.Û²Û°Û±Û¹-Û°Û±-Û°Û¸.Û°Û³-ÛµÛ´-Û±Û²-Û¶Û´Û¸.00.log

是的！问题出在Unicode编码问题上（可能是NTFS和UTF-8之间）！虽然这些是log文件，也许不重要，但这个问题可能存在于其他地方！

正如你所猜到的，文件名的损坏部分是日期和时间。所以（不幸的是），我被迫将个人化的Windows用户帐户的日期和时间格式从我最喜欢的（波斯语（伊朗））恢复为英语（美国）：

问题立刻解决：
