First off let me say that I'm using the taskjuggler exporter with tj3,
so it should work.

As far as I know setting the org-export-taskjuggler-default-reports
should work. As I agree that this is a bit clumsy and sets the reports
for all projects. I'm setting the variable in a file variable like so
(the compile-command is optional but you need to adapt it to match the
location of your tj3 binary and your file name):

# Local Variables:
# org-export-taskjuggler-target-version: 3.0
# org-export-taskjuggler-default-reports: ("include \"reports.tji\"")
# compile-command: "~/.gem/ruby/1.9.1/bin/tj3 yourfilename.tjp"
# End:

Then I define the reports in a separate file which is included similar
to the solution you outline below.

I guess I should have some default report definitions for tj3 in the
exporter itself. The tj3 reports are quite massive and it is hard to
come by some which could be included in the Emacs source (you need
copyright assignments). Maybe the ones I have in my reports.tji could

Yes I agree, see above.

I can see a use case for this with regards to reports. But what is the
use case if you'd place this inside tasks? The problem with literal
sections of taskjuggler is where to place them. Something might me
related to the project header, other stuff to the reports, etc.

The exporter just makes the task_id locally unique. That's what tj
expects. From your usage I guess that you have a lot of tasks with the
same name (probably within different hierarchies). Both methods you
outline could be implemented. Which one is more general?

Could you not set org-export-taskjuggler-default-reports to "include
\"reports.tji\""? Otherwise you can use file variables as I outlined

I'm happy to take you up on this offer. The worg page is a lot of work,
as it has all these screen shots. I'd be happy if you could update it
once you get all of this working.

I have it installed on an old machine.

I still prefer the old reports. But I guess yes, the exporter should
move on and support tj3 out of the box. The two main problems are

1. default reports with copyright assignments. As I include this in the
   Emacs source we need to have assignments. I can't just take the ones
   from the tj3 manual (I'd have to ask the author first).

2. A way to invoke the view (as seamless as before). For tj 2.4 I was
   able to just invoke the taskjuggler gui with the exported tjp file.
   For tj3 the exporter needs to somehow find out which reports are
   generated (HTML, text, csv) and then invoke the appropriate viewer.
   This might be simplified I take some assumptions, but I haven't come
   up with a clever way to do this.
