Quick question: I’m trying to build a jar with all dependencies of my gradle project.
So I create a `Jar` task that will use all dependencies :
```
val dist = project.tasks.create("dist", Jar::class.java) {
     from(configurations.runtime.map { if (it.isDirectory) it else zipTree(it) })
}
```

But I got an error:

```
 from(configurations.runtime.map { if (it.isDirectory) it else zipTree(it) })
                                                       ^ Unresolved reference: isDirectory
```

If I’m printing the configuration (`println(configurations.runtime.javaClass)`), I got that: `class org.gradle.api.internal.DefaultNamedDomainObjectCollection$ExistingNamedDomainObjectProvider_Decorated`

I would expect something like `FileCollection` or `Configuration`. What I’m doing wrong? :thinking_face:

I think `NamedDomainObjectCollection` require you to retrieve the object from the collection before calling stuff on it

`from(configurations.runtime.get().map { … })` works :thumbsup:
