Ошибка при создании BlobContext с использованием jclouds в приложении Spring MVC

Question

У меня есть веб-приложение Spring MVC 4.0.1, которому необходимо загрузить файлы в файлы облачных хранилищ Rackspace. Для этого я использую Apache jClouds. При попытке создать Blobstore, используя следующий код:

BlobStoreContext context = ContextBuilder.newBuilder("cloudfiles-us").credentials("username","password").buildView(BlobStoreContext.class); 

я получаю следующее исключение:

com.google.inject.CreationException: Guice creation errors:

Я не могу понять это, так как его довольно много в первой строке кода примера в этом точка ...

Вы используете jclouds 1.6.x или 1.7.0 с Java 7u51? Если это так, возможно, вы столкнулись с https://issues.apache.org/jira/browse/JCLOUDS-427. Вы можете обойти это, перейдя на Java 7u45 или обновив до jclouds 1.7.1.
