Hi all, first time posting here, good to be here. 
I hope this topic is in the right category; please move if not.
As the title says, I’m after some help on getting Compose Multiplatform to work with Maven. I’ve read the Getting Started README in the GitHub project, but that only talks about using Gradle. I’ve tried looking at the Gradle example project and copying what it’s doing, but I haven’t been successful. I’ve tried some web searching, but haven’t found any info on using it with Maven or fixing the problems I’m facing.
The issues I’m running into are:
- Maven tries to include Android libraries, while Gradle is smart enough to exclude them. I was able to solve that by excluding all the Android libraries, but I’d like to not have to do that.
- Maven tries to download the AAR files, and again, Gradle doesn’t. I have no idea how to tell Maven to not download AAR files. It wouldn’t even matter, except Maven apparently cannot find the AAR files.
org.jetbrains.compose.material:material-ripple:aar:1.2.1 was not found in https://maven.pkg.jetbrains.space/public/p/compose/dev - Maven can’t find some of the Compose libraries:
org.jetbrains.compose.desktop:desktop-jvm-windows-x64:jar:1.2.1 was not found in https://maven.pkg.jetbrains.space/public/p/compose/dev
My pom file looks like this:

I can get it to work if I use the desktop-jvm library rather than the desktop-jvm-windows-x64 library, but then I get a runtime error instead:
Exception in thread "main" java.lang.NoSuchMethodError: 'void androidx.compose.ui.window.Application_desktopKt.application$default(boolean, kotlin.jvm.functions.Function1, int, java.lang.Object)'
at au.com.skater901.TestUIKt.main(TestUI.kt:17)
at au.com.skater901.TestUIKt.main(TestUI.kt)
My code looks like this:
package au.com.skater901
import androidx.compose.material.MaterialTheme
import androidx.compose.material.Text
import androidx.compose.runtime.Composable
import androidx.compose.ui.window.Window
import androidx.compose.ui.window.application
@Composable
public fun TestUI() {
MaterialTheme {
Text("Pathfinder Character Generator")
}
}
public fun main(): Unit {
application {
Window(onCloseRequest = ::exitApplication) {
TestUI()
}
}
}
Please help! I just want to quickly and easily make a UI, not stuff around with dependency management. 
It’d be nice if Jetpack Compose could be used with Maven, but I wasn’t invested enough in that outcome to spend the time required to figure it out.
