Interface TaskContainer
- All Superinterfaces:
- Collection<Task>,- Configurable<NamedDomainObjectContainer<Task>>,- DomainObjectCollection<Task>,- DomainObjectSet<Task>,- Iterable<Task>,- NamedDomainObjectCollection<Task>,- NamedDomainObjectContainer<Task>,- NamedDomainObjectSet<Task>,- PolymorphicDomainObjectContainer<Task>,- Set<Task>,- TaskCollection<Task>
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 Details- 
findByPathLocates 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. - Parameters:
- path- the path of the task to be returned
- Returns:
- The task. Returns null if so such task exists.
 
- 
getByPathLocates 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. - Parameters:
- path- the path of the task to be returned
- Returns:
- The task. Never returns null
- Throws:
- UnknownTaskException- If no task with the given path exists.

registerTaskProvider<Task> register(String name, Action<? super Task> configurationAction) throws InvalidUserDataException Defines a new task, which will be created and configured when it is required. A task is 'required' when the task is located using query methods such asTaskCollection.getByName(java.lang.String), when the task is added to the task graph for execution or whenProvider.get()is called on the return value of this method.It is generally more efficient to use this method instead of NamedDomainObjectContainer.create(java.lang.String, org.gradle.api.Action)orcreate(java.lang.String), 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 and configuration until required.- Specified by:
- registerin interface- NamedDomainObjectContainer<Task>
- Parameters:
- name- The name of the task.
- configurationAction- The action to run to configure the task. This action runs when the task is required.
- Returns:
- A Providerwhose value will be the task, when queried.
- Throws:
- InvalidUserDataException- If a task with the given name already exists in this project.
