runIde or CustomRunIdeTask can't override idea.* properties

[jonathanlermitage]

What happened?

I would like to override the idea.log.path when running runIde, using plugin v2.
My build.gradle.kts has:

runIde {
    jvmArgs("-Didea.log.path=custom/logs/")
    jvmArgs("-Pidea.log.path=custom/logs/")
}

then run gradlew runIde.

I also tried

register("myRunIde", CustomRunIdeTask::class) {
    jvmArgs("-Didea.log.path=custom/logs/")
    jvmArgs("-Pidea.log.path=custom/logs/")
}

then run gradlew myRunIde.

The logs are still located in the regular log folder (sandboxed dir / ide version / log). I checked the idea.log.path property with VisualVM, and they are no affected by my changes.
Please note I tried to override both the JVM property and the System property, because when running runIde with no customization, I observed both properties are set.

All runnable tasks are now working on jvmArgumentProviders to respect Providers.
Apparently, values defined that way override regular arguments passed with jvmArgs().

To utilize jvmArgumentProviders in your setup, you can:

jvmArgumentProviders += CommandLineArgumentProvider {
    listOf("-Didea.config.path=custom/config")
}

FTR, with beta9, there's a new way of creating custom tasks introduced:

val myRunIde by intellijPlatformTesting.runIde.registering {
    // ...

    task {
        jvmArgumentProviders += CommandLineArgumentProvider {
            listOf("-Didea.config.path=custom/config")
        }
    }
}
