Question

当我尝试涉及compileKotlin（或compileTestKotlin）的任务时，我收到此警告，结果是构建过程持续时间长：< / p>

无法执行增量编译：无法连接到Kotlin编译守护程序

无法连接到kotlin守护程序。使用后备策略。

我不确定问题是否与我的操作系统（Windows）有关，但我在具有Linux OS的远程计算机上具有相同的项目（带有同步文件），并且该问题不存在。参见下面的比较：

我的远程计算机（ Linux ）上的项目，但Kotlin来源（在一个模块中）稍有变化：

$ ./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

本地计算机（ Windows ）上的同一项目，但具有相同的更改：

> gradlew build

尤其是上面两个示例中的构建持续时间（以及在Windows计算机上compileKotlin任务之后的警告）。即使我的本地计算机（Windows）具有更强大的硬件，但结果却相反（Gradle守护程序同时在两者上运行）。

为了进一步分析，我还在两台计算机上发布了gradle -v和java -version的输出：

Linux ：

$ ./gradlew -v

更新1：

将Gradle JVM设置为JDK 8不会有问题。但是使用JDK 9+可以看到问题。

更新2：

我将Kotlin插件从1.3.10更新为1.3.11。此外，还测试了1.3.20-eap-52。但是问题仍然存在。

更新3：

我使用compileKotlin选项运行Gradle的--debug任务以获取更多信息。输出中最重要的部分是：

^{注意：当Gradle守护程序运行时，以下任务已运行，Kotlin编译守护程序已停止（如果已运行），并且对Kotlin源进行了一些更改。}

I。。当使用 JDK 8 作为Gradle的JVM时（ OK ）：

上面的日志（第二个）中有一些可疑事件，但是我无法完全理解它们的含义，并且它们是否与我的问题有关：

为什么发生两次（完全相等）尝试来启动 Kotlin编译守护程序？
存在一些错误。但是他们都是在警告Kotlin的守护程序问题之后。
最新错误/警告：
```
[ERROR] [system.err] warning: the '-d' option with a directory destination is ignored because '-Xbuild-file' is specified
```
是最可疑的东西！因为这是您在其他日志中找不到的唯一消息。另请参见here。我在another post中问过这个问题。

Answer 1

最后，我找到了问题的根源……几天后！

我发现问题出在我的用户帐户上。因此决定将任何与用户相关的事物恢复到其第一状态。在清除Temp文件夹（在AppData\local\中）期间，我偶然看到了以下文件：

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！问题来自 unicode编码问题 （可能在NTFS和UTF-8之间）！尽管这些文件是log文件，并且它们的名称也许并不重要，但是这个问题可能存在于其他地方！

您可以猜测，文件名的损坏部分为 date和time 。因此（很不幸），我不得不将 Windows用户帐户的日期和时间格式的个性化设置从我最喜欢的（Persian (Iran)）恢复为English (United States)：

第二个过程是 Kotlin编译守护程序 。

还有log个文件：

kotlin-daemon.2019-01-08.03-51-11-111.00.log
kotlin-daemon.2019-01-08.03-51-11-111.00.log.lck

^{（请注意，.log.lck文件在以前的状态下不存在！）}

Answer 2

就我而言，我已通过清除“用户”文件夹中的某些缓存进行了修复，尤其是：

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

不确定哪一个有所作为，但清除所有这些后，错误消失了。

Gradle：无法连接到Windows上的Kotlin守护程序
