Is your request related to a problem? Please describe.
In Eclipse, the naming restrictions are not the same for projects and packages (e.g. '-' is allowed in a project name, but not in a package name). When developing a plugin for GAMA, the project name is used to generate the name of the gaml.additions package, but if the name does not match the restrictions, the package is not created and there are no error messages.
Describe the solution you'd like
A warning could be added to the plugin development tutorials to inform about this problem.
