Calling this method from a task action is not supported when configuration caching is enabled.

The timeout of this task.
task myTask {
timeout = Duration.ofMinutes(10)
}
The Thread executing this task will be interrupted if the task takes longer than the specified amount of time to run. In order for a task to work properly with this feature, it needs to react to interrupts and must clean up any resources it opened.
By default, tasks never time out.

void
doNotTrackState
(String
reasonNotToTrackState)
Do not track the state of the task.
Instructs Gradle to treat the task as untracked.
Adds the given finalizer tasks for this task.
task taskY {
finalizedBy "taskX"
}
See here for a description of the types of objects which can be used to specify a finalizer task.
boolean

Determines if this task has the given property. See here for details of the properties which are available for a task.
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.
void
onlyIf
(Closure
<?>
onlyIfClosure)
Closure
<?>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() }
Note: This method is incubating and may change in a future version of Gradle.
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("run only in production environment", new Spec<Task>() { boolean isSatisfiedBy(Task task) { return isProductionEnvironment(); } });
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(); } });
Returns the value of the given property of this task. This method locates a property as follows:
- If this task object has a property with the given name, return the value of the property.
- If this task has an extension with the given name, return the extension.
- If this task's convention object has a property with the given name, return the value of the property.
- If this task has an extra property with the given name, return the value of the property.
- If not found, throw
MissingPropertyException
Sets a property of this task. This method searches for a property with the given name in the following locations, and sets the property on the first location where it finds the property.
- The task object itself. For example, the
enabled
project property. - The task's convention object.
- The task's extra properties.
If the property is not found, a MissingPropertyException
is thrown.
TaskDependency
shouldRunAfter
(Object
...
paths)
Object
...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.

(Provider
<? extends BuildService
<?>>

Provider
<? extends BuildService
<?>>Registers a BuildService
