A modern programming language that makes developers happier.

kotlinlang

I'm following the official tutorial to create a desktop app: <https://www.jetbrains.com/help/kotlin-multiplatform-dev/compose-multiplatform-create-first-app.html#run-your-application-on-desktop>

But when I try to build/run, I get the error: `Could not find or load main class MainKt` .Please help.

Ah, this is because the wizard changed to now put the code in the package specified on the website instead of the root package.

If you used the default settings in the wizard, this should work:
```desktopRun -DmainClass=com.jetbrains.demo.MainKt --quiet```

An even easier way is to use the gutter icon next to the `main` function to start the application:

Just realized there's a simpler way than specifying the `mainClass`, you can just run the `:composeApp:run` Gradle task on its own and that should work as well.

Thank you <@U2UJXRF0W>! You saved my day!
