how to copy all source jars using gradle

Question

We have an old playframework 1.2.x version where we copy all the jars to project/lib so playframework can consume them. We would LOVE to copy all the source jars as well so

Answer 1

Here eskatos solution translated in Kotlin DSL:

tasks {
    "copySourceJars"(Copy::class) {
        val sources = configurations.runtime.resolvedConfiguration.resolvedArtifacts.map {
            with(it.moduleVersion.id) { 
                dependencies.create(group, name, version, classifier = "sources") 
            }
        }
        from(
            configurations.detachedConfiguration(*sources.toTypedArray())
                .resolvedConfiguration.lenientConfiguration.getFiles(Specs.SATISFIES_ALL)
        )
        into(File("some-directory"))
    }
}
