API Documentation: | TaskContainer |
---|
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) | Deprecated Creates a |
create(name, configureClosure) | Deprecated Creates a |
create(name, type) | Deprecated Creates a |
create(name, type, constructorArgs) | Deprecated Creates a |
create(name, type, configuration) | Deprecated Creates a |
create(name, configuration) | Deprecated Creates a |
create(options) | Deprecated Creates a |
create(options, configureClosure) | Deprecated 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. |
maybeCreate(name) | Looks for an item with the given name, creating and adding it to this container if it does not exist. |
maybeCreate(name, type) | Looks for an item with the given name and type, creating and adding it to this container if it does not exist. |
named(name) | Locates a task by name, without triggering its creation or configuration, failing if there is no such object. |
named(name, type) | Locates a object by name and type, failing if there is no such object. |
named(name, type, configurationAction) | Locates a object by name and type, failing if there is no such object. The given configure action is executed against the object before it is returned from the provider. |
named(name, configurationAction) | Locates a object by name, failing if there is no such object. The given configure action is executed against the object before it is returned from the provider. |
named(nameFilter) | Returns a collection containing the objects with names matching the provided filter. The returned collection is live, so that when matching objects are added to this collection, they are also visible in the filtered collection. |
register(name) | 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 |
register(name, type) | 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 |
register(name, type, constructorArgs) | Defines a new task, which will be created when it is required passing the given arguments to the |
register(name, type, configurationAction) | 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 as |
register(name, configurationAction) | 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 as |

This method is an intermediate operation. It does not change the realized/unrealized state of the elements in the collection.
Note: This method is deprecated and will be removed in the next major version of Gradle.
Creates a Task
with the given name and adds it to this container.
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.
Note: This method is deprecated and will be removed in the next major version of Gradle.

the task before it is returned by this method.

Creates a Task
with the given name and type, passing the given arguments to the @Inject

will be thrown

Creates a Task
with the given name and of type DefaultTask
, configures it with the given action, and adds it to this container.
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.
Note: This method is deprecated and will be removed in the next major version of Gradle.
Creates a Task
and adds it to this container. A map of creation options can be passed to this method
to control how the task is created. The following options are available:
Option | Description | Default Value |
| The name of the task to create. | None. Must be specified. |
| The class of the task to create. | DefaultTask |
| The closure or Action to
execute when the task executes. See Task.doFirst(org.gradle.api.Action) . | null |
| Replace an existing task? | false |
| The dependencies of the task. See here for more details. | [] |
| The group of the task. | null
|
| The description of the task. |
null |
| The arguments to pass to the task class constructor. |

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.
If a task with the given name already exists in this container and the
option is not set to true, an exception is thrown.overwrite

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.
