Is it possible to use the same code for jvmMain and androidMain but with slightly different dependencies? This does not work, because then jna classes are duplicated:

val jvmMain by getting {
    dependencies {
        implementation("net.java.dev.jna:jna:${Versions.jna}")
    }
}
val androidMain by getting {
    dependsOn(jvmMain)
    dependencies {
        implementation("net.java.dev.jna:jna:${Versions.jna}@aar")
    }
}

You could try something like

val jvmAndAndroidMain by creating
val jvmMain by getting {
    dependsOn(jvmAndAndroidMain)
    dependencies {
        implementation("net.java.dev.jna:jna:${Versions.jna}")
    }
}
val androidMain by getting {
    dependsOn(jvmAndAndroidMain)
    dependencies {
        implementation("net.java.dev.jna:jna:${Versions.jna}@aar")
    }
}

IDE support for this is not always great though, and you might need to manually wire some expect/actual declarations depending on how the rest of your project is configured.

I already tried that, but jmvAndAndroidMain contains JNA dependencies, so it does not compile.
