Kotlin in QT Project. How?

From the looks of if Kotlin is to replace Java, so you likely have to look into the direction of JNI.

I want to add Kotlin class into QT Project and seeking solution.
Ask the Kotlin community if there is a way to call Kotlin code from C++ code. If it exists, then you can use Kotlin in Qt. If it doesn't exist, then you're out of luck.
Qt is a C++ library (mostly).
Also, which platforms do you plan to target? Windows/Linux/Android/...?

I am seeking solution for implementing Kotlin into Qt for Android and build it automatically like I am doing right now with Java
And why can't you ask such a precise question from the beginning? I asked you two times to give a better description of you task, but you refused up to now.
So it seems the answer is currently: NO.

@aha_1980 It seems you only DO NOT know answer. There are solution to use Kotlin in C++ and it's in official Kotlin doc. It's making through plain C wrapper. Natively Kotlin support Objective-C and plain C. And you have to build Kotlin part like shared object for Android or static lib for iOS and then within wrapper written on Objective-C/CPP or plain C add it to CPP project that might be using in Android or iOS application. I just been seeking in-box solution in Qt (because there are global troubles in compilers, you have to build it separately and wrap it into plain C or in Java and then to use it through JNI - this way haven't tested it yet) and the question was super clear: "Is there any way to add Kotlin in QT Project?" - It was my first question. In return you asked me not about details, you asked me about WHY I need this ... I've been 2 times explaining to you what I need. And now you writing me "And why can't you ask such a precise question from the beginning?" - really???
Issue closed ...

@sgaist Directly it's not possible because of compilers, there need to be built Kotlin first on native compiler like *.so, after it wrap it into Java and after add all of it into Qt. But this way haven't tested by me yet. It's only theory.

This topic is quite old but I thought I would answer it for others that might think about using Kotlin in Qt projects.
You can do it (at least for Android) via JNI! See this presentation from QtWS21: https://www.youtube.com/watch?v=nmvurCcsWos&t=50s

You can use Qt in Java (so also in Kotlin) using QtJambi.
I made the application Mouse Melon with Kotlin and Qt.
