Ошибка установки Maven в учебном проекте GraniteDS 3.0

Я пытаюсь установить пример проекта GraniteDS с помощью maven 3.1.1 под 64-разрядной версией Windows 7.
Я следовал руководству, опубликованному на:
https://github.com/graniteds-tutorials/Graniteds-tutorial-data

Воспроизведенные шаги:

1. Установлен maven 3.1.1 (извлек двоичный zip и создал переменные M2_HOME, M2 и добавил «% M2_HOME%\bin» в PATH)

2. Установил git 1.8.5.2 для windows

3. Запустите git shell и выполните:

   cd c:\dev\ws_flex\fb4.7

   git clone http://github.com/graniteds-tutorials/graniteds-tutorial-data.git

   cd graniteds-tutorial-data

   mvn clean install asciidoctor:process-asciidoc -Dserver=spring -Dclient=air

И я получаю Ошибка:

and more...

и несколько предупреждений об отладке
