Specified by:

createProject in interface ECPProjectManager

Parameters:

provider - the ECPProvider of this project

name - the name of the project

properties - the project properties

Returns:

created ECPProject

Throws:

ECPProjectWithNameExistsException - when a project with the same name already exists
