A TaskContainer is responsible for managing a set of Task instances.
You can obtain a TaskContainer instance by calling Project.getTasks(), or using the
tasks property in your build script.
| Method | Description |
containerWithType(type) | Creates a regular container that wraps the polymorphic container presenting all elements of a specified type. |
create(name) | Creates a |

create(options) | Creates a |
create(options, configureClosure) | Creates a |
findByPath(path) | Locates a task by path. You can supply a task name, a relative path, or an absolute path. Relative paths are interpreted relative to the project for this container. This method returns null if no task with the given path exists. |
getByName(name) | Locates an object by name, failing if there is no such object. |
getByName(name, configureClosure) | Locates an object by name, failing if there is no such object. The given configure closure is executed against the object before it is returned from this method. The object is passed to the closure as its delegate. |
getByName(name, configureAction) | Locates an object by name, failing if there is no such object. The given configure action is executed against the object before it is returned from this method. |
getByPath(path) | Locates a task by path. You can supply a task name, a relative path, or an absolute path. Relative paths are interpreted relative to the project for this container. This method throws an exception if no task with the given path exists. |

If a task with the given name already exists in this container and the overwrite
Creates a Task adds it to this container. A map of creation options can be passed to this method to
control how the task is created. See TaskContainer.create(java.util.Map) for the list of options available. The given
closure is used to configure the task before it is returned by this method.
After the task is added, it is made available as a property of the project, so that you can reference the task by name in your build file. See here for more details.
Locates a task by path. You can supply a task name, a relative path, or an absolute path. Relative paths are interpreted relative to the project for this container. This method returns null if no task with the given path exists.
T getByName(String name)
Locates an object by name, failing if there is no such object.
Locates an object by name, failing if there is no such object. The given configure closure is executed against the object before it is returned from this method. The object is passed to the closure as its delegate.

TaskProvider<T>Action<? super T>Locates a object by name, without triggering its creation or configuration, failing if there is no such object. The given configure action is executed against the object before it is returned from the provider.
TaskProvider<Task>register(String name)
TaskProvider<Task>Defines a new task, which will be created when it is required. A task is 'required' when the task is located using query methods such as TaskCollection.getByName(java.lang.String), when the task is added to the task graph for execution or when Provider.get() is called on the return value of this method.
It is generally more efficient to use this method instead of TaskContainer.create(java.lang.String), as that method will eagerly create the task, regardless of whether that task is required for the current build or not. This method, on the other hand, will defer creation until required.
TaskProvider<T>register(String name, Class<T>
TaskProvider<T>Class<T>Defines a new task, which will be created when it is required. A task is 'required' when the task is located using query methods such as TaskCollection.getByName(java.lang.String), when the task is added to the task graph for execution or when Provider.get() is called on the return value of this method.
It is generally more efficient to use this method instead of TaskContainer.create(java.lang.String, java.lang.Class, org.gradle.api.Action) or TaskContainer.create(java.lang.String, java.lang.Class), as those methods will eagerly create and configure the task, regardless of whether that task is required for the current build or not. This method, on the other hand, will defer creation until required.
TaskProvider<T>register(String name, Class<T>Object...
TaskProvider<T>Class<T>Object...Defines a new task, which will be created when it is required passing the given arguments to the @Inject-annotated constructor. A task is 'required' when the task is located using query methods such as TaskCollection.getByName(java.lang.String), when the task is added to the task graph for execution or when Provider.get() is called on the return value of this method. All values passed to the task constructor must be non-null; otherwise a NullPointerException will be thrown
