public interface Task
extends Comparable<Task>, ExtensionAware
```
A Task represents a single atomic piece of work for a build, such as compiling classes or generating javadoc.

Each task belongs to a Project. You can use the various methods on TaskContainer to create and lookup task instances. For example, TaskContainer.create(String) creates an empty task with the given name. You can also use the task keyword in your build file:
```
 task myTask
 task myTask { configure closure }
 task myTask(type: SomeType)
 task myTask(type: SomeType) { configure closure }
 
```
Each task has a name, which can be used to refer to the task within its owning project, and a fully qualified path, which is unique across all tasks in all projects. The path is the concatenation of the owning project's path and the task's name. Path elements are separated using the ":" character.

Task Actions

A Task is made up of a sequence of Action objects. When the task is executed, each of the actions is executed in turn, by calling Action.execute(T). You can add actions to a task by calling doFirst(Action) or doLast(Action).

Groovy closures can also be used to provide a task action. When the action is executed, the closure is called with the task as parameter. You can add action closures to a task by calling doFirst(groovy.lang.Closure) or doLast(groovy.lang.Closure).

There are 2 special exceptions which a task action can throw to abort execution and continue without failing the build. A task action can abort execution of the action and continue to the next action of the task by throwing a StopActionException. A task action can abort execution of the task and continue to the next task by throwing a StopExecutionException. Using these exceptions allows you to have precondition actions which skip execution of the task, or part of the task, if not true.

Task Dependencies and Task Ordering

A task may have dependencies on other tasks or might be scheduled to always run after another task. Gradle ensures that all task dependencies and ordering rules are honored when executing tasks, so that the task is executed after all of its dependencies and any "must run after" tasks have been executed.

Dependencies to a task are controlled using dependsOn(Object...) or setDependsOn(Iterable), and mustRunAfter(Object...), setMustRunAfter(Iterable), shouldRunAfter(Object...) and setShouldRunAfter(Iterable) are used to specify ordering between tasks. You can use objects of any of the following types to specify dependencies and ordering:
- A String, CharSequence or groovy.lang.GString task path or name. A relative path is interpreted relative to the task's Project. This allows you to refer to tasks in other projects. These task references will not cause task creation.
- A Task.
- A TaskDependency object.
- A TaskReference object.
- A Buildable object.
- A RegularFileProperty or DirectoryProperty.
- A Provider object. May contain any of the types listed here.
- A Iterable, Collection, Map or array. May contain any of the types listed here. The elements of the iterable/collection/map/array are recursively converted to tasks.
- A Callable. The call() method may return any of the types listed here. Its return value is recursively converted to tasks. A null return value is treated as an empty collection.
- A Groovy Closure or Kotlin function. The closure may take a Task as parameter. The closure or function may return any of the types listed here. Its return value is recursively converted to tasks. A null return value is treated as an empty collection.
- Anything else is treated as an error.
Using a Task in a Build File

Dynamic Properties

A Task has 4 'scopes' for properties. You can access these properties by name from the build file or by calling the property(String) method. You can change the value of these properties by calling the setProperty(String, Object) method.
- The Task object itself. This includes any property getters and setters declared by the Task implementation class. The properties of this scope are readable or writable based on the presence of the corresponding getter and setter methods.
- The extensions added to the task by plugins. Each extension is available as a read-only property with the same name as the extension.
- The convention properties added to the task by plugins. A plugin can add properties and methods to a task through the task's Convention object. The properties of this scope may be readable or writable, depending on the convention objects.
- The extra properties of the task. Each task object maintains a map of additional properties. These are arbitrary name -> value pairs which you can use to dynamically add properties to a task object. Once defined, the properties of this scope are readable and writable.
Dynamic Methods

A Plugin may add methods to a Task using its Convention object.

Parallel Execution

By default, tasks are not executed in parallel unless a task is waiting on asynchronous work and another task (which is not dependent) is ready to execute. Parallel execution can be enabled by the --parallel flag when the build is initiated. In parallel mode, the tasks of different projects (i.e. in a multi project build) are able to be executed in parallel.

  - onlyIf
```
void onlyIf(Closure onlyIfClosure)
```
    Execute the task only if the given closure returns true. The closure will be evaluated at task execution time, not during configuration. The closure will be passed a single parameter, this task. If the closure returns false, the task will be skipped.
    
    You may add multiple such predicates. The task is skipped if any of the predicates return false.
    
    Typical usage:myTask.onlyIf { isProductionEnvironment() }
    
    Parameters:
    
    onlyIfClosure - code to execute to determine if task should be run
  - doNotTrackState

    7.3
    
    See Also:
    
    UntrackedTask
  - notCompatibleWithConfigurationCache
```
@Incubating
void notCompatibleWithConfigurationCache(String reason)
```
    Specifies that this task is not compatible with the configuration cache.
    Configuration cache problems found in the task will be reported but won't cause the build to fail.
    
    The presence of incompatible tasks in the task graph will cause the configuration state to be discarded at the end of the build unless the global configuration-cache-problems option is set to warn, in which case the configuration state would still be cached in a best-effort manner as usual for the option.
    
    IMPORTANT: This setting doesn't affect how Gradle treats problems found in other tasks also present in the task graph and those could still cause the build to fail.
    
    Since:
    
    7.4
  - onlyIf
```
void onlyIf(Spec<? super Task> onlyIfSpec)
```
    Execute the task only if the given spec is satisfied. The spec will be evaluated at task execution time, not during configuration. If the Spec is not satisfied, the task will be skipped.
    
    You may add multiple such predicates. The task is skipped if any of the predicates return false.
    
    Typical usage (from Java):
```
myTask.onlyIf(new Spec<Task>() {
    boolean isSatisfiedBy(Task task) {
       return isProductionEnvironment();
    }
 });

    Parameters:
    
    onlyIfClosure - code to execute to determine if task should be run
  - setOnlyIf
```
void setOnlyIf(Spec<? super Task> onlyIfSpec)
```
    Execute the task only if the given spec is satisfied. The spec will be evaluated at task execution time, not during configuration. If the Spec is not satisfied, the task will be skipped.
    
    The given predicate replaces all such predicates for this task.
    
    Parameters:
    
    onlyIfSpec - specifies if a task should be run
  - getState
```

  - mustRunAfter
```
Task mustRunAfter(Object... paths)
```
    Specifies that this task must run after all of the supplied tasks.
```
 task taskY {
     mustRunAfter "taskX"
 }
 
```
    For each supplied task, this action adds a task 'ordering', and does not specify a 'dependency' between the tasks. As such, it is still possible to execute 'taskY' without first executing the 'taskX' in the example.
    
    See here for a description of the types of objects which can be used to specify an ordering relationship.
    Parameters:
    
    paths - The tasks this task must run after.
    
    Returns:
    
    the task object this method is applied to
  - setMustRunAfter
```
void setMustRunAfter(Iterable<?> mustRunAfter)
```
    Specifies the set of tasks that this task must run after.
```
 task taskY {
     mustRunAfter = ["taskX1", "taskX2"]
 }
 
```
    For each supplied task, this action adds a task 'ordering', and does not specify a 'dependency' between the tasks. As such, it is still possible to execute 'taskY' without first executing the 'taskX' in the example.

```
    Specifies that this task should run after all of the supplied tasks.
```
 task taskY {
     shouldRunAfter "taskX"
 }
 
```
    For each supplied task, this action adds a task 'ordering', and does not specify a 'dependency' between the tasks. As such, it is still possible to execute 'taskY' without first executing the 'taskX' in the example.
    
    See here for a description of the types of objects which can be used to specify an ordering relationship.
    Parameters:
    
    paths - The tasks this task should run after.
