get All Tasks
Returns the tasks which are included in the execution plan. The order of the tasks in the result is compatible with the constraints (dependsOn/mustRunAfter/etc) set in the build configuration. However, Gradle may execute tasks in a slightly different order to speed up the overall execution while still respecting the constraints.
Return
The tasks. Returns an empty list if no tasks are to be executed.
Throws
When this graph has not been populated.
