# Interface ProjectDescriptor

public interface ProjectDescriptor

A `ProjectDescriptor` declares the configuration required to create and evaluate a `Project`.

A `ProjectDescriptor` is created when you add a project to the build from the settings script, using `Settings.include(String...)`. You can access the descriptors using one of the lookup methods on the `Settings` object.
