[MODULE]Get main project and get its git information

I'm using this code to get the selected project, but getMainProject always returns null so it falls back to getting all projects.

Code:
 Project[] projects;
 Project project = OpenProjects.getDefault().getMainProject();
 projects = project == null ? OpenProjects.getDefault().getOpenProjects() : new Project[]{project};
 for (Project p : projects) {
   ProjectInformation info = ProjectUtils.getInformation(p);
   System.out.println(info.getName());
 }



After that, I want to extract the project's credentials and info to connect to the repository. I couldn't find any example or hint on how to do that. 
Can anyone set me in the right direction?
