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.

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

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

gradle jdk is set to the same as your JAVA_HOME?

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

`echo $JAVA_HOME`  returns nothing when running in ubuntu terminal

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.

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?

I will try and figure out the JAVA_HOME variable :thumbsup:

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

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).

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.

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

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. :smiley:

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

Got it working now. Need to make sure that:
• `Project Structure &gt; Project &gt; Project SDK` is using a (WSL) version.
• `Settings &gt; Build &gt; Build Tools &gt; 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 :stuck_out_tongue:

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.

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