I have also configured the desktop by following values -
But I am getting error.

compose.desktop {
application {
mainClass = "desktop/src/jvmMain/kotlin/Main.kt"
nativeDistributions {
targetFormats(TargetFormat.Dmg, TargetFormat.Msi, TargetFormat.Deb)
packageName = "KMPTemplate"
packageVersion = "1.0.0"
}
}
}
Solution
Problem is in the desktop's build.gradle.kts, in compose.desktop extension. For mainClass you should specify qualified Java class name that hold main method - entry point of program. In template you've chosen main is top-level function outside any package, top-level Kotlin functions and properties are accessible as members of special class (Kotlin will add Kt to the filename) it will be MainKt.
compose.desktop {
application {
mainClass = "MainKt"
//...
}
}
If you decide to put your main function in some package, e.g. package foo.bar, then you should use foo.bar.MainKt
