I'm trying to setup my Kotlin project to run in WSL, but I just get this error and have no clue on how to fix it.

[jeggy]

I have installed default-jre , but can't figure out how get intellij to use this

[jeggy]

running any gradle tasks like this ./gradlew build , works without any problems. But I would like IntelliJ to be fully compatable with my project

[Colton Idle]

gradle jdk is set to the same as your JAVA_HOME?

[jeggy]

I have no clue. I just know this and none of the options under "Gradle JVM" work

[jeggy]

echo $JAVA_HOME returns nothing when running in ubuntu terminal

[Colton Idle]

I don't use windows or WSL for that matter, but I do know that I've had a bunch of issues with the JDKs not matching up with the one that is set for my project and the one that is output when I echo.

Personally, I would focus on trying to get JAVA_HOME to echo properly as I think a lot of things in intellij require it.

[jeggy]

I always have a bunch of issues with gradle and jvm settings, which is why I started using this:

compileKotlin { kotlinOptions.jvmTarget = "15" }
compileTestKotlin { kotlinOptions.jvmTarget = "15" }
java {
    toolchain {
        languageVersion.set(JavaLanguageVersion.of(15))
    }
}

But I don't think intellij uses this for anything?

[jeggy]

I will try and figure out the JAVA_HOME variable 👍

[Colton Idle]

Intellij seems to look here for env vars

https://github.com/JetBrains/intellij-community/blob/master/plugins/terminal/resources/jediterm-bash.in

and so with that said I think it you find that you can't echo JAVA_HOME inside of terminal then that might be your problem

[Colton Idle]

I've also seen that "shell integration" being selected is sometimes a culprit.

Anyway. I hope I did not mislead you. Just giving you a heads up that this was the issue for me (but not on windows or wsl).

[jeggy]

I have setup intellij to use wsl ubuntu in the terminal settings, that worked in windows projects and now in wsl projects it's also working fine.
Seems it's just gradle/kotlin that is not working.

[jeggy]

I got it working!

[Colton Idle]

Oooh! What was it?

[jeggy]

just ran ./gradlew build which then did downloaded all of the required stuff, then when opening that gradle jvm settings page, it now gave me the option to select WSL version

[Colton Idle]

Ah nice. 💯

[Colton Idle]

I'm picking up a windows laptop in about ~3 months and def want to use WSL so hoefully this info will come in handy. 😃

[jeggy]

or not, it gave me a new error and without any information...

Got it working now. Need to make sure that:
• Project Structure > Project > Project SDK is using a (WSL) version.
• Settings > Build > Build Tools > Gradle has:
◦ A WSL path for Gradle user home
◦ Use Gradle from is set to gradle-wrapper.properties file
◦ Gradle JVM is using a (WSL) version
And if intellij can't find any WSL versions, just run ./gradlew build. And if this command doesn't work, then you can always google it 😛

[jeggy]

Nah not fully working, I'll just give up and try again in a few months. I'm guessing JetBrains are working on improving the experience on this.

[Colton Idle]

Maybe worth filing a bug?

Maybe I will try more in my free time. Too time expensive to get it to work in work hours 😛
