Gradle: How to partition a task into sequentially executed actions

Question

Is it possible to nest tasks in gradle, such as

task foo(dependsOn: jar){
    // task 1
    // task 2
    // task 3
    .
    .
    .
    // task n
}

where the order of execution is jar > foo > task 1 > task 2 > task 3 > ... > task n? I don't want the nested tasks (i.e. task 1, task 2, and etc.) to be exposed to the user. I only want the foo task to be exposed.

Answer 1

It looks like you can simply do the following,

task foo(dependsOn: ['clean', 'jar']){
    foo << {
        println "First"
    }
    foo << {
        println "Second"
    }

    foo << {
        println "Third" 
    }
    .
    .
    .
}

where << is shorthand for doLast. I think the neat thing about this approach is that only foo is exposed..the nested tasks remain hidden from the end user. And if you execute foo, you'll get

First
Second
Third
