Resetting the UP-TO-DATE property of gradle tasks?

Question

Is there a way I can force a gradle task to run again, or reset all tasks back to the not UP-TO-DATE state?

Answer 1

I had a tough case where setting outputs.upToDateWhen { false } inside the task or adding the flag --rerun-tasks didn't help since the task's setOnlyIf kept being set to false each time I ran it.

Adding the following to build.gradle forced the execution of myTask:

gradle.taskGraph.whenReady { taskGraph ->
  def tasks = taskGraph.getAllTasks()
  tasks.each {
    def taskName = it.getName()
    if(taskName == 'myTask') {
      println("Found $taskName")

      it.setOnlyIf { true }
      it.outputs.upToDateWhen { false }
    }
  }
}
