GanttProject 2.6.6

GanttProject 2.6.6 fixes a few annoying issues and provides compatibility with Java 7 on Mac OSX

It turned out that application launcher which was built into GanttProject.app was not aware of Java 7 and insisted on installing Java 6. GanttProject 2.6.6 for Mac OSX is repackaged with other launcher, and we hope that it will work fine with both Java 6 and Java 7 from now on.

Bugfixes and translation updates:
  • Gantt chart rendering issues when some of the tasks are collapsed 
  • Timeline labels are saved to project file and survive project reopenings and application restarts
  • WebDAV locking functions made working
  • Mac OS X users can now move tasks on the chart with Shift+left button
  • Hungarian, Korean, Chinese, Polish and Norwegian translations update
  • Added Hungarian and Chile calendars
You can download GanttProject 2.6.6 from our web site or from our pages on SourceForge.

The first beta of new GanttProject 2.7

Meet the first beta build of the new major update. GanttProject 2.7 "Ostrava"is available for download from our web site and SourceForge.
Ostrava is the third largest city in Czech Republic. It is located in Moravian region in the north-east, close to Poland and Slovakia.
While this build should be fairly stable, it is possible that something is broken. We'll appreciate testing and bug reports, especially related to our new features.

Now, the headlines!

Task cost calculation

This is one of the most requested features in our bugtracker. What is implemented in GP 2.7 is really simple, but we hope that  many of you will find it useful. 

So, we've added Cost property to our tasks model and user interface. It sits in the Resources tab:

Cost fields in the Task Properties dialog

Cost can be calculated automatically, which is the default setting, or typed manually. When calculated automatically, it is a sum of payment rates of assigned resources, each multiplied by their utilization and task duration. Naturally, in the resource properties dialog one can specify payment rate for each resource. At the moment we support standard rate only, with no specific currency, per our default time unit which is day. So, if you assign 1 resource with standard rate 50 to a task with duration 5 days, its calculated cost will be 250. If you assign one more resource with standard rate 100 but 50% utilization, the total cost will be 250 + 250 = 500

The cost of a summary task is the sum of subtask costs, but can also be set manually.

Cost and standard rate can be shown as columns in task/resource tables, can be exported to PDF, HTML, CSV, and hopefully MS Project import/export is also aware of them. We would appreciate testing of MS Project interoperability in this aspect, though.
iCalendar in the list of import tools

Import holiday calendars in iCalendar format

GanttProject has been using holiday calendars in its own simple format for years, but we understand that it is not the most popular format in the world, and people normally would prefer to publish calendars in other formats. iCalendar is one of the most popular, and there are lots of calendars in this format available from Mozilla or iCalShare. Now you can import holiday calendars into GanttProject with our new import tool. It can import .ics files, so you'll need to download them or export from other tools, and although iCalendar format supports more than just holidays, GanttProject will import all events as holidays into current project's calendar.

Weekend exceptions

One more highly requested calendar-related feature is ability to make working some particular weekend day. For instance, in some countries, e.g. in Russia, if a holiday happens on Tuesday, it will be "merged" with the closest weekend, and Monday will be non-working too (thus we get 4 days looong weekend), but one of the next weekends will have one working day.

Such use case could not be represented in GanttProject previously. In GP 2.7 it is possible to add "exceptions" and make particular weekends working. This feature sits in the refactored Public Holidays dialog which is now way more functional.

Adding weekend exception

There are a few less important changes, library updates, and so on. There is one removal: FOP based PDF export, which was deprecated since GP 2.5, is not included into GanttProject 2.7.

Installation requirements

GanttProject 2.7 requires Java 7 or Java 8 and is available as ZIP archive only. You can run it on any Java-enabled platform (Windows, Mac OSX, Linux, etc.), provided that you can run java command from your terminal window. Please refer to installation instructions on our Wiki pages.


We expect that files created in the previous versions of GanttProject should work fine in GP 2.7, and that GanttProject 2.6 can read files created in GP 2.7, skipping data related to newly added features of course. Please let us know if you notice any compatibility problems.

Official download locations

Unfortunately Project Hosting on Google Code which we are using stopped its download service. You can download GanttProject 2.7 beta I from our web site or from our pages on SourceForge
