私はこのXtestコードを使用してデモhomeAutomation言語github sourceを作成していますが、自動コードが生成されたときに "タイプミスマッチ：クラスからクラスに変換できません"というようなAbstractHomeAutomationRuntimeModuleファイルにエラーが発生しました。さらにreferanceのためのPIC 
型の不一致：Class <RulesGenerator>からClass <？に変換できません。拡張IGenerator2> xtestエラー
私はエラーが
AbstractHomeAutomationRuntimeModuleファイルを生成し、この自動であるAbstractHomeAutomationRuntimeModule RulesGenerator.xtendファイルを追加した後/*
