code: private void removeDuplicatedProjects(DbSession session, String projectKey) {
      List<ComponentDto> duplicated = dbClient.componentDao().selectComponentsHavingSameKeyOrderedById(session, projectKey);
      for (int i = 1; i < duplicated.size(); i++) {
        dbClient.componentDao().delete(session, duplicated.get(i).getId());
      }
    }
docs: On MySQL, as PROJECTS.KEE is not unique, if the same project is provisioned multiple times, then it will be duplicated in the database.
  So, after creating a project, we commit, and we search in the db if their are some duplications and we remove them.
