I would like to play music when all the tasks are done. I don't know how to hook it with the last task/event.

So far I managed to download and play music and I can execute it manually.

Here is my code (mostly working):

def tempSound = "/tmp/gradleBuildFinished.wav"

task downloadMusic {
    doLast {
        println "downloadMusic"

        def sounds = [
                "http://www.xxx.zzz/hos1.wav",
                "http://www.xxx.zzz/hos2.wav",
        ]

        def r = new Random()
        def soundIndex = r.nextInt(sounds.size())

        println "Deleting temp sound: "   delete(tempSound)

        exec {
            commandLine("bash", "-c", "curl "   sounds.get(soundIndex)   " > "   tempSound)
        }
    }
}

task playMusic {
    dependsOn downloadMusic

    doLast {
        println "playMusic"

        assert file(tempSound).exists()

        ("afplay "   tempSound).execute()
    }
}

gradle.buildFinished{
    // how to execute playMusic? It will trigger when all tasks are done, right?
}

OK, here is the answer. The main task should have been finalized by the assemble task.

def tempSound = "/tmp/gradleBuildFinished.wav"

task downloadAssembleSound() {
    doLast {
        println "> Task :downloadAssembleSound"

        def sounds = [
                "http://www.xxx.zzz/hos",
        ]

        def r = new Random()

        def soundIndex = r.nextInt(sounds.size())
        def soundNumber = r.nextInt(3)   1

        delete(tempSound)

        def sound = sounds.get(soundIndex)   soundNumber   ".wav"
        println "Fetching.... "   sound

        exec {
            commandLine("bash", "-c", "curl "   sound   " > "   tempSound)
        }
    }
}

task playAssembleSound {
    dependsOn { downloadAssembleSound }
    doLast {
        println "> Task :playAssembleSound"
        assert file(tempSound).exists()
        ("afplay "   tempSound).execute()
    }
}

tasks.whenTaskAdded { task ->
    if (task.name.contains('assemble') && task.name.contains('Debug')) {
        task.finalizedBy {
            playAssembleSound
        }
    }
}
