Ошибка при настройке ускорителя B2C в hybris 5.7

Я перешел по ссылке ниже, чтобы установить магазин B2B и B2C параллельно.

https://wiki.hybris.com/pages/viewpage.action?spaceKey=accdoc&title=Installing+B2C+and+B2B+Accelerators+in+Parallel

После, следуя инструкциям, я смог получить магазин электроники и электроинструмента OOB.

Теперь я собираюсь создать свой собственный магазин B2C с помощью modulegen.

Но я получаю сообщение об ошибке:
