What's the operator << (double less than) in gradle?

Question

4.times { counter ->
    task \"task$counter\" << {
        println \"I\'m task number $counter\         


        

Answer 1

Basically this is a leftShift operator - You can find more details here.

In gradle << operator is used to add action to a particular task. A task consists of multiple actions that are run (in order they were added) during the execution of the task. << just adds an action to tasks collection of actions. More about tasks and actions can be found here.
