Gradle: Couldn't connect to Kotlin daemon on Windows


When I try a task that involves a compileKotlin (or compileTestKotlin), then I receive this warning and the result is unpleasant long duration of the build process:

Could not perform incremental compilation: Could not connect to Kotlin compile daemon

Could not connect to kotlin daemon. Using fallback strategy.


I'm not sure the issue is related to my OS (Windows) or not, but I have the same project (with synchronized files) on a remote machine with Linux OS and the issue doesn't exist there. See below comparison:

  1. The project on my remote machine (Linux) with a little change in Kotlin sources (in one module):

    $ ./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
    
  2. Same project on my local machine (Windows) with same change:

    > gradlew build                                                                                       
    
    > Task :backend:compileKotlin                                                                         
    Could not perform incremental compilation: Could not connect to Kotlin compile daemon                 
    Could not connect to kotlin daemon. Using fallback strategy.

    BUILD SUCCESSFUL in 14s                                                                               
    46 actionable tasks: 17 executed, 29 up-to-date
    

Especially see build duration time in above two samples (and the warning after compileKotlin task on Windows machine). Even though my local machine (Windows) has more powerful hardware, but the result is the opposite (Gradle daemon is running on both).


In order to further analyzability I also publish the output of gradle -v and java -version on both machines:

Global gradle.properties files on two machines are exactly same (and there is no poject-local gradle.properties file for none):

(without comments)


UPDATE 1:

There is no problem when Gradle JVM has been set to JDK 8. But with JDK 9+ you can see the issue.


UPDATE 2:

I updated my Kotlin plugin from 1.3.10 to 1.3.11. Also, tested 1.3.20-eap-52. But the issue persists.


UPDATE 3:

I ran Gradle's compileKotlin task with --debug option to get more information. The most important parts of the output are:

Note: Below tasks have been run when Gradle daemon was running, Kotlin compile daemon was stopped (if already running) and a little change has been made in a Kotlin source.

I. When using JDK 8 as Gradle's JVM (OK):

There are some suspected events in the above logs (second), but I can't exactly understand the meaning of them and that they are related to my problem or not:

  1. Why two (exactly equal) tries has occurred to start Kotlin compile daemon?
  2. There are some errors. But they are all after warnings about Kotlin's daemon problem.
  3. The latest error/warning:

    [ERROR] [system.err] warning: the '-d' option with a directory destination is ignored because '-Xbuild-file' is specified
    

    is the most suspected thing! Because it's the only message you can't find in other logs. Also see here. I asked about it in another post.


Solution

  • Finally, I found the source of the issue ... After some days!

    I found out the issue is from my user account. So decided to revert any user-dependent thing to its first state. During clearing Temp folder (in AppData\local\) accidentally I saw these files:

    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
    

    Yes! The problem has come from unicode encoding issues (probably between NTFS and UTF-8)! Although these are log files and maybe not important their names, this issue can exist somewhere else!

    As you can guess, damaged part of file names are date & time. So (unfortunately) I forced to revert my personalizations of Windows user account's date & time formats from my favorite (Persian (Iran)) to English (United States):

    enter image description here

    And the problem solved immediately:

    The second process is Kotlin compile daemon.


    Also log files:

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

    (Note that .log.lck file didn't exist in previous state!)
