Adding tasks in other ways

Until now, we have added tasks to our build project using the task keyword followed by the name of the task. But there are more ways to add tasks to our project. We can use a string value with the task name to define a new task:

task 'simple' << { task ->
    println "Running ${task.name}"
}

We can also use variable expressions to define a new task. If doing so, we must use parentheses, because otherwise the expression cannot be resolved. The following sample script defines a variable simpleTask with the string value simple. This expression is used to define the task. The result is that our project now contains a task with the name simple:

def simpleTask = 'simple'

task(simpleTask) << { task ->
    println "Running ${task.name}"
}

We can run the tasks task to see our newly created task:

$ gradle -q tasks
...

We can also use the power of Groovy to add new tasks. We can use Groovy's GString notation to dynamically...
