I’ve configured Proguard to my liking based on the documentation which creates a nice obfuscated min.jar . The problem is that native distribution packages don’t want to use the obfuscated jar to create .dmg, even when I’ve clearly specified the location.

import com.netguru.extensions.desktopMain
import org.jetbrains.compose.compose
import org.jetbrains.compose.desktop.application.dsl.TargetFormat

buildscript {
    dependencies {
        classpath(libs.desktop.proguard)
    }
}

plugins {
    kotlin("multiplatform")
    alias(libs.plugins.compose)
}

group = libs.versions.project.group.get()
version = libs.versions.project.version.get()

kotlin {
    jvm("desktop")
    sourceSets {
        desktopMain {
            dependencies {
                implementation(compose.desktop.currentOs)
                implementation(project(":application"))
            }
        }
    }
}

compose.desktop {
    application {
        mainClass = "MainKt"

        nativeDistributions {
            targetFormats(TargetFormat.Dmg, TargetFormat.Msi, TargetFormat.Deb)
            packageName = libs.versions.desktop.packageName.get()
            packageVersion = libs.versions.desktop.packageVersion.get()
        }
        disableDefaultConfiguration()
        from(kotlin.targets["desktop"])
        val file: File? =
            fileTree("build/compose/jars").files.firstOrNull { file: File -> file.name.contains(".min.jar") }
        mainJar.set(file)
    }
}
tasks.register("createDesktopPackage") {
    group = "desktop package"
    dependsOn("obfuscate")
    dependsOn("package")
}

tasks.register<proguard.gradle.ProGuardTask>("obfuscate") {
    val packageUberJarForCurrentOS by tasks.getting
    dependsOn(packageUberJarForCurrentOS)
    val files = packageUberJarForCurrentOS.outputs.files
    injars(files)
    outjars(files.map { file -> File(file.parentFile, "${file.nameWithoutExtension}.min.jar") })

    val library = if (System.getProperty("java.version").startsWith("1.")) "lib/rt.jar" else "jmods"
    libraryjars("${System.getProperty("java.home")}/$library")

    configuration("<http://proguard-rules.pro|proguard-rules.pro>")
}

I have created a solution for that: https://gist.github.com/mcpiroman/cf511c5f9312a59e8f821706738eeab3

This solution works only on jvm not on multiplatform

you are jumping into the problem that I’ve been trying to properly solve for a few weeks now.

i'm curious if it is possibility to solve this
