Task is always up to date

Question

I've got a gradle build with a task like the following

task createFolders {
  file(rootFolder).mkDirs()
}

Note that in the real system there are about 15 folders getting created during this task.

This task always reports as UP-TO-DATE when I run the task, even if I run it directly after deleted the folders being created. I have several tasks that depend on this task and they run.

How do I tell gradle that this task is only up to date if all the created folders exist?

Answer 1

It happens because folders are created during configuration phase. Add an action:

task createFolders << {
  file(rootFolder).mkDirs()
}
