Adding additional properties to tasks

A task object already has several properties and methods. But we can add any arbitrary new property to a task and use it. In the following sample, we print the value of the task property message. The value of the property is assigned with the statement simple.message = 'world':

task simple << {
    println "Hello ${message}"
}
simple.message = 'world'

When we run the task we get the following output:

$ gradle -q simple
Hello world
