  - named
```
<T extends Named> T named(java.lang.Class<T> type,
                          java.lang.String name)
                   throws ObjectInstantiationException
```
    Creates a simple immutable Named object of the given type and name.
    The given type can be an interface that extends Named or an abstract class that 'implements' Named. An abstract class, if provided:
    
    Must provide a zero-args constructor that is not private.
    
    Must not define or inherit any instance fields.
    
    Should not provide an implementation for Named.getName() and should define this method as abstract. Any implementation will be overridden.
    
    Must not define or inherit any other abstract methods.
    
    An interface, if provided, must not define or inherit any other methods.
    
    Objects created using this method are not decorated or extensible.
    Throws:
    
    ObjectInstantiationException - On failure to create the new instance.
    
    Since:
    
    4.0
  - newInstance
```
<T> T newInstance(java.lang.Class<? extends T> type,
                  java.lang.Object... parameters)
           throws ObjectInstantiationException
```
    Create a new instance of T, using parameters as the construction parameters.
    The type must be non-final, and can be a class, abstract class or interface.
    
    Objects created using this method are decorated and extensible, meaning that they have DSL support mixed in and can be extended using the `extensions` property, similar to the Project object.
    
    An @Inject annotation is required on any constructor that accepts parameters because JSR-330 semantics for dependency injection are used. In addition to those parameters provided as an argument to this method, the following services are also available for injection:
    
    ObjectFactory.
    
    ProjectLayout.
    
    ProviderFactory.
    
    ExecOperations
    
    FileSystemOperations
    Throws:
    
    ObjectInstantiationException - On failure to create the new instance.

```
    Creates a new NamedDomainObjectContainer for managing named objects of the specified type.
    
    The specified element type must have a public constructor which takes the name as a String parameter. The type must be non-final and a class or abstract class.
    
    Interfaces are supported if they declare a read-only name property of type String, and are otherwise empty or consist entirely of managed properties.
    
    All objects MUST expose their name as a bean property called "name". The name must be constant for the life of the object.
    
    The objects created by the container are decorated and extensible, and have services available for injection. See newInstance(Class, Object...) for more details.
