I have this jvmJar task to build a jar for my backend

val jvmJar by tasks.getting(Jar::class) {
    doFirst {
        manifest {
            attributes["Main-Class"] = "${ProjectSettings.packageName}.backend.BackendAppKt"
            from(
                configurations
                    .getByName("runtimeClasspath")
                    .map { if (it.isDirectory) it else zipTree(it) }
            )
        }
    }
}

this task is failing now with this error

> Task :backend:jvmJar FAILED

FAILURE: Build failed with an exception.

any idea how we can fix that ?

i just do shadowJar

your code works for me in a kotlin-jvm project
but i needed to add the following lines because of unrelated issues

isZip64 = true
duplicatesStrategy = DuplicatesStrategy.INCLUDE

If you have your project publicly visible can you share it ?
