Hello, good day to all of you good people. Question: Is there a way to configure multiplatform gradle plugin's jvmRun task and set the main class (see error in forwarded message) Thanks a bunch!

[Vampire]

Alternatively to the API you found, you could also set project property or system property mainClass, or jvmRun.mainClass.

[Richard Glen]

Hi. Thanks for the reply, how do I do the first one? Can I set mainClass directly somewhere? I’m already doing the latter part (see my reply in the message I forwarded).

[Vampire]

No, you are not

[Vampire]

I said you can set these two as project property or system property, alternatively to the DSL you used

[Vampire]

For example in gradle.properties, or via -P or -D and so on.

[Richard Glen]

Ohh. That’s a nice info. A cool usecase would be to set main class differently. Would you kindly point a reference to this? Is this mentioned somewhere in the docs (the fact that you can set mainClass via project or system property)? May I know other options I can set in the system/project properties too?

[Vampire]

I looked at the source code

[Richard Glen]

haha of course! I’ll get used to reading the source code someday. By source code, you mean the multiplatform plugin source code?

Just add the application plugin: https://gitlab.com/opensavvy/notes/kotlin-fullstack/-/blob/main/app-cli/build.gradle.kts?ref_type=heads#L35

(notice the jvm { withJava() } , it's important for the application plugin to work)

[Richard Glen]

Hi. Thanks for the reply. I didn't want to add the application plugin. I'm wondering for its need to be added because It seems multiplatform plugin already has a jvmRun task.

[CLOVIS]

Is it new? I don't remember using it. I can't find any documentation about it other than the original issue (but there's no explanation of how it's supposed to be used)

[Vampire]

Yes, new in 1.9.20

Well, that test answers your question; the configuration is

kotlin {
    jvm {
        mainRun {
            mainClass.set("…")
        }
    }
}

[Vampire]

Yes, he found out already within his mentioned thread in #multiplatform in the original post here. And alternatively you can use the two properties I mentioned and both either as system property or project property.

Thanks a lot for accommodating! Kotlin is awesome!
