FileCollection files

                Iterator<File> iterator() {
                    files.iterator()
                }

                TaskDependency getBuildDependencies() {
                    files.getBuildDependencies()
                }
            }

            task foo {
                outputs.file "foo.txt"
                doFirst {}
            }

            task bar {

Instead, they will both directly implement `Dependency`.

As such, the following methods of `ProjectDependency` and `FileCollectionDependency` will no longer be available:

- `resolve`
- `resolve(boolean)`
- `getBuildDependencies`

Consider the following scripts that showcase the deprecated interface and its replacement:
