Can intelliJ detect the JVM toolchain/target version of some file based on Gradle configuration? Thread.id is deprecated in Java 19 (which is my JAVA_HOME). But I'm compiling with jvmTarget = "1.8" so it shouldn't be a warning?

Changing Project settings fixes it but it feels wrong to have to duplicate this?

Also interestingly, it seems to be bound to the SDK version while I would expect it to be bound to the Language Level instead

If I remember correctly, this can be controlled by the Java toolchain version in the Gradle build file (https://docs.gradle.org/current/userguide/toolchains.html), I don't think the Kotlin compiler plugin will automatically take over the Java toolchain JVM version, but you could at least use a common property for it, something like (assuming a build.gradle.kts):

val jvmVersion = 19

java {
    toolchain.languageVersion.set(JavaLanguageVersion.of(jvmVersion))
}

tasks.compileKotlin {
    kotlinOptions {
        jvmTarget = "$jvmVersion"
    }
}

That part works. My issue is with IntelliJ is not picking this up

[mbonnin]

i.e. it shows false positive warnings

ah okay, then I misunderstood!

I think it on the way. Scroll down to Java SDK detected from the Gradle toolchain https://blog.jetbrains.com/idea/2023/02/intellij-idea-2023-1-eap-6

Oohhooh very nice

I'm already on 2023.1 though 🤔 . Let me try again

So that doesn't work out of the box (I'm using toolchains with Java17)
