Developing models in Capsis with JDK 1.8 and Subversion (SVN)

Un résumé de la procédure en français est disponible.

This documentation is for Capsis modellers (according to the Capsis charter), it explains how to get a full local copy of Capsis on their computer to be able to add their own work in the platform.

The Capsis software sources are hosted on a Subversion (SVN) repository.

A Login is required (see section 2. below).

Important note

If you are not already a Capsis modeller and if you would like to integrate a model in Capsis, please see How to join Capsis and contact the development team (see contact) in order your registration to be validated.

1. Install Java SE 8 (JDK)

Capsis relies on Java version 1.8 (or Java 8): Java Development Kit Standard Edition version 1.8.

To check if your installation of java is correct, check the FAQ, section 3.6. The system must find a jdk 1.8.x. If correct, jump directly to section 2.

On windows

  • Modify the PATH environment variable according to your installation directory
    • Click Start > Settings > Control Panel > System > Advanced > Environment Variables.
    • In the PATH system variable (not in PATH user variable), add the location of the bin/ folder of the installed JDK at first position. A typical value is: C:\Program Files\Java\jdk1.8.0_<version>\bin (you may seek this directory in a file manager and copy / paste the path).
    • A “;” must be added between the paths in the PATH variable.
    • You should only have one bin/ directory for a JDK in the path at a time. Those following the first instance will be ignored.

On Linux

  • If the PATH variable is to be updated, have a look in /etc/environment, ~/.bashrc or ~/.profile files. You may have a look at this doc to change the PATH under Linux Ubuntu.
  • The path to the location of the bin/ folder of the installed JDK must be added at first position of the PATH variable. A “:” must be added between the paths in the PATH variable.

→ To check if your installation of java is now correct, check the FAQ.

2. Create an amap-dev account

Capsis files are hosted on the amap-dev development server. To access to Capsis files, you need to create an account on the server.

Your login/password will be used to access to SVN files, but also to modify the Capsis Wiki web site and to manage Capsis on the amap-dev development server (e.g. ask for a bug correction / a new feature).

3. Get a local copy of the project (checkout)

SmartSVN makes it possible to access to the SVN repository.

  • Download and install SmartSVN :
  • Start SmartSVN
    • if Smartsvn ask for svnserve and svnadmin, click Cancel
    • During installation, SmartSVN may ask you if you want to evaluate the Pro version. You can ignore this message
  • Choose Check out project from repository
  • Quick Checkout :
  • Accept the server fingerprint if proposed
  • Enter your login and password

Note: This is your new login password you entered when you registered on amap-dev at section 2

  • Validate and finish

Possible trouble

The checkout operation may fail after a while with an error message, e.g.

APR does not understand this error code ra_serf: The server sent a truncated HTTP response body

In this case, try to continue the operation this way in SmartSVN:

  • select the capsis4 (top level) directory in the 'Directories' panel,
  • Modify > Cleanup
  • Update

This should continue the process. This operation might be done several times in case your internet connection is not optimal.

4. SVN usual operations

Later when you will need to get the last changes of the server downloaded to your local copy, you will use SmartSVN and the Update command.

When you will have to upload your own changes onto the server, you will use the SVN Commit command.

You may ask for support to well understand the process when updating your local copy or commiting your changes the first time.

For more information on the SVN commands, see this doc: SVN update and commit.

5. Recompile and start Capsis

  • Open a terminal (Dos prompt under windows, shell under linux)
  • Go to the capsis4 directory with cd
  • Recompile the project
ant compile
  • If you need a full recompilation (should be done after each SVN update)
ant clean compile

Note : If there are errors, please contact the capsis team.

  • Then you can launch Capsis.

The capsis.bat or scripts are used to start capsis :

Under Windows:


Under Linux:


Note : you can also use

ant run

6. Configure your editor

7. Other useful command

See ant.
