Interface TaskExecutionGraph
A TaskExecutionGraph
is responsible for managing the execution of the Task
instances which
are part of the build. The TaskExecutionGraph
maintains an execution plan of tasks to be executed (or
which have been executed), and you can query this plan from your build file.
You can access the TaskExecutionGraph
by calling Gradle.getTaskGraph()
.
In your build file you can use gradle.taskGraph
to access it.
The TaskExecutionGraph
is populated only after all the projects in the build have been evaulated. It
is empty before then. You can receive a notification when the graph is populated, using whenReady(groovy.lang.Closure)
or addTaskExecutionGraphListener(TaskExecutionGraphListener)
.
