Hi,

tj3 support is still buggy. And tj export gets confused with the task_id tags.
It does not generate unique IDs nor does  it have manual ID marking. So it gets
scrampled. So, for a bigger project it does not really work.

Verify to use

Org Export Taskjuggler Target Version:

3.0

I have used the following settings with M-x customize-group -> org-export-taskjuggler
and worked for me as a first shot with tj3:


Org Export Taskjuggler Default Global Properties:

shift s40 "Part time shift" {
  workinghours wed, thu, fri off
}

account cost "Project Cost" {
  aggregate tasks
}

account rev "Payments" {
}

Org Export Taskjuggler Default Reports:

# Now the project has been specified completely. Stopping here would
# result in a valid TaskJuggler file that could be processed and
# scheduled. But no reports would be generated to visualize the
# results.

  hidereport @none

Hello,

I'm trying to use the export to TJ3 on Windows (I installed Ruby from Cygwin),
but don't succeed to get the first view of the project, as shown on
http://orgmode.org/worg/org-tutorials/org-taskjuggler.html.

I'm using the very first example given at line "Your resulting Org mode
project file will look somewhat like the following:", add the required tag
:taskjuggler_project: to the node "Accounting Software".

Then, I export it to TJ (C-c C-e j) and run tj3 against it:

$ tj3 org-tj3.tjp

Results:

So, it seems that the output file is not up-to-date (tj v3.3.0), or do I miss
something?

Best regards,
