help with "condition could not be met"

[Ken Geis]

Hi. When I run the following file, I get the error:

• Error: Task task1 (2024-12-02-10:00-+0000) must end before start (2024-12-02-00:00-+0000) of task deadline1. This condition could not be met.

This seems perfectly plannable. Can someone help me understand why TaskJuggler can't handle it and how I might make it work?

Thanks,

Ken

task task1 "task1" {

task deadline1 "deadline 1" {

}
task deadline2 "deadline 2" {

Do I understand correctly --- deadline1 and deadline2 are milestones?

So the order is do task 2 before deadline 2, in time to do task 1 before deadline 1?

Sorry,

I still don’t understand. I’ve transformed it in this way and it works

resource persona1 "Persona1" {}

resource persona2 "Persona2" {}

task task1 "task1" {

    

     effort 1w

     allocate persona1

#--       allocate persona2

#--   precedes !deadline1

#-- depends !task2

}

#--task deadline1 "deadline 1" {

#--  start 2024-10-01

#--  allocate persona1

#--  effort 1w

#--}

task task2 "task2" {

  depends !task1

  effort 1w   

  allocate persona1

  precedes !deadline2

}

task deadline2 "deadline 2" {

  start 2024-12-02

}

 #---------------------inizio a fare i report -----

textreport frame "" {

  textreport index "Overview" {

    formats html

    center '<[report id="overview"]>'

  }

}

  #--------------------creo il report overview-------

taskreport overview "" {

  columns bsi { title 'WBS' },

          name, start, end, effort, cost,

          revenue, chart   #-{ ${TaskTip} }

}

We can work on it to improve it, step by ste. Isn’t it?

I would like to use it and I made my simple step ahead, if someone add something to this example, would be grate.

Thank you

Renato
