The TaskJuggler Project Management Software

Project Management beyond Gantt Chart Drawing

The TaskJuggler User Manual

TaskJuggler comes with extensive user documentation. An online version can be found here.

Local Help

The same information that is available via the above link is also available locally. You can get the help directly in your shell

tj3man <keyword>

or in your browser

tj3man --html <keyword>

The latter defaults to using Firefox. Please see

tj3man --help

how to use a different browser. If you omit the keyword, you will either get a list of all keywords (shell) or the full user manual (browser).

Source Code Documentation

This is not something a normal user would want to read. But if you want to tweak TaskJuggler, the source code documentation is an excellent place to get started.

TaskJuggler Workshop and Presentation Slides

It usually takes no more than 2 to 3 hours to get productive with TaskJuggler. But for larger project plans some deeper knowledge of TaskJuggler can be helpful. Therefor, we have created a workshop that provides a training for people that are generally familiar with project management, but have no or little knowledge of TaskJuggler. It covers all basic and most advanced features and can be held in two 3 to 4 hour sessions. The workshop is a hands-on training and participants should have the latest stable TaskJuggler version available on their computers to complete the exercises. Please contact one of the developers if you are interested in such a workshop. A copy of the slides in Open Document Format or PDF is available.

Please note that the workshop slides have not yet been adapted to TaskJuggler version 3. They are for TaskJuggler version 2 only!

German speaking users may want to have a look at a presentation about TaskJuggler 3.x.

The website is now served from an AWS S3 bucket

TaskJuggler has moved to a new server

Reported on 2014-12-23

For the past 7 years, the TaskJuggler web site has been hosted on the same server. It was about time to upgrade to more snappy hardware. We also switched the OS version and setup everything from scratch. Please report to the mailing lists in case you see any issues.

TaskJuggler 3.5.0 has been released

Reported on 2013-06-30

This release took a little longer to bake due to a change of jobs on my end. The long wait comes with some long wanted features like hammock tasks. Many error messages were made clearer and are hopefully now more informative. We also made the switch to Ruby 2.0 as recommended Ruby version. 1.9 is still fully supported and even 1.8.7 and later work with some restrictions. [Read More...]
