:question: How can I access `packageName` defined ...

# compose-desktop

❓ How can I access packageName defined inside build.gradle.kts inside main method? Is there any API available?

This sounds more like a gradle question, I'd probably suggest asking in some gradle forums.

There are couple of ways you can achieve this.
• Pass it as JVM args and read it using System.getProperty()
• Pass it as application args . Here is how i am passing the project , kotlin version, group id and main class

compose.desktop {
    application {
        mainClass = "aaa.xxxx.yyyy.AppKt"
        args(
            project.version.toString(),
            kotlin.coreLibrariesVersion,
            project.group.toString(),
            mainClass.toString()
        )

From the App.kt main, you can read it as args[0], args[1] etc

Ohhh, that's nice. Thanks suresh 🇮🇳

I write a .prperties file with gradle stuff after gradle task processResources and include it in the jar
(don't forget to put the src/main/resources/buildProperties.properties file in your .gitignore

val processResources by tasks.existing {
    val writeProperties by tasks.existing
    finalizedBy(writeProperties)
}
val writeProperties by tasks.registering {
    doLast {
        val srcResourcesProperties = File(projectDir, "src/main/resources/buildProperties.properties")
        val buildResourcesProperties = File(project.buildDir, "resources/main/buildProperties.properties")

        for (propFile in listOf(srcResourcesProperties, buildResourcesProperties)) {
            propFile.printWriter().use { out ->
                out.println("projectDir=${projectDir}")
                out.println("projectDirEcore=${project(":ecore").projectDir}")
                out.println("projectDirBackendServer=${project(":backend:server").projectDir}")
                out.println("projectDirDalcommon=${project(":common:dalcommon").projectDir}")
                out.println("projectDirFrontendUI=${project(":frontend:ui").projectDir}")
            }
        }
    }
}
