kotlin multiplatform shadow fat jar and runShadow task? - gradle

Question

I have a fairly standard kotlin multiplatform (mpp) build.gradle.kts that uses application plugin and com.github.johnrengelman.shadow
I succeeded to create an java -jar executable fat jar:
new solution:
EDIT:
I extended a line to #Pylyp Dukhov solution:
classpath += files("$buildDir/processedResources/jvm/main")
tasks {
named<JavaExec>("run") {
standardInput = System.`in`
classpath += objects.fileCollection().from(
named("compileKotlinJvm"),
configurations.named("jvmRuntimeClasspath")
)
classpath += files("$buildDir/processedResources/jvm/main")
}
shadowJar {
manifest { attributes["Main-Class"] = theMainClass }
archiveClassifier.set("fat")
val jvmJar = named<org.gradle.jvm.tasks.Jar>("jvmJar").get()
from(jvmJar.archiveFile)
configurations.add(project.configurations.named("jvmRuntimeClasspath").get())
}
}
old solution:
application {
mainClass.set(theMainClass)
}
tasks {
val shadowCreate by creating(com.github.jengelman.gradle.plugins.shadow.tasks.ShadowJar::class) {
manifest { attributes["Main-Class"] = theMainClass }
archiveClassifier.set("fat")
mergeServiceFiles()
from(kotlin.jvm().compilations.getByName("main").output)
configurations = mutableListOf(kotlin.jvm().compilations.getByName("main").compileDependencyFiles as Configuration)
}
val build by existing {
dependsOn(shadowCreate)
}
}
but now I struggle on how to get the application gradle run task respectively the shadow gradle runShadow task to execute correctly.
Anybody Any Ideas (kotlindsl) ?

I'm using the following:
tasks.named<JavaExec>("run") {
classpath += objects.fileCollection().from(
tasks.named("compileKotlinJvm"),
configurations.named("jvmRuntimeClasspath")
)
}
