scheduling towards a deadline (retroplanning)

[niol]

In the schduling I'm trying to accomplish, I have to make sure some stuff is done before some work from another larger project can start. Therefore, I work planning tasks in reverse (retroplanning).

For instance, I do not know if the impossibility to schedule the following is a bug or a feature request.

project proj "Project" 2015-10-01 - 2016-12-31 {
}

task work "pre-Works" {
    scheduling alap
    task first "First task" {
        duration 1w
    }
    task second "Second task" {
        depends !first
        duration 1w
    }
}

task "Work" {
    depends work.second
    start 2016-01-01
}

attributes like 'depends' or 'start' change the 'scheduling' direction. You need to override the scheduling after you have used those attributes.

Sorry but I cannot fix the example above so as to express what I want. Can you be more explicit about how to make it work?

Try something like this:

task work "pre-Works" {
task first "First task" {
duration 1w
precedes !second
}
task second "Second task" {
duration 1w
precedes work1
}
}

task work1 "Work" {
end 2016-01-01
}
