It is possible using the duplicate-module target of the Ant's build.xml file to duplicate an existing module located in the capsis4/src directory by giving it a new package name, a new module name and a new prefix. The user chooses the new package name and the new prefix, and the new module name is created automatically from the new package name.

Note: the new prefix can be the same as the one of the initial module.

In order to duplicate a module, you have to type the following command from the capsis4 directory:

On Linux/MacOS:

sh ant duplicate-module -Dpackage.name=packagename -Dnew.package.name=newpackagename -Dnew.prefix=Newprefix

On Windows:

ant duplicate-module -Dpackage.name=packagename -Dnew.package.name=newpackagename -Dnew.prefix=Newprefix

where:
- package.name is the package name of the initial module (module to duplicate stored in capsis4/src directory);
- new.package.name and new.prefix are respectively the package name and the prefix of the new module (module to create in capsis4/src directory).

For example, the following command (on Linux/MacOS):

sh ant duplicate-module -Dpackage.name=training -Dnew.package.name=training2 -Dnew.prefix=Tra2

will create from the training package (that is Training module) a new module having the following characteristics:
- package name: training2
- module name: Training2 (default value generated from package name)
- prefix: Tra2
