Загрузка библиотеки Android в Bintray — параметр userOrg игнорируется

Я пытаюсь загрузить библиотеку Android в Bintray, используя это руководство: https://inthecheesefactory.com/blog/how-to-upload-library-to-jcenter-maven-central-as-dependency/en

Все работает нормально, пока я не пытаюсь запустить bintrayUpload, когда получаю следующую ошибку:

Не удалось выполнить задачу ':MAS:bintrayUpload'.

Не удалось создать пакет 'user/maven/my-repo': HTTP/1.1 404 Not Found [сообщение: Repo 'maven' не найден]

Я думаю, проблема в том, что репозиторий принадлежит организации на Bintray. Но ищет его под пользователем. т.е. user/maven/my-repo должен быть организация/maven/my-repo.

Мои local.properties выглядят так:

...    
bintray.userOrg=organisation
bintray.user=user
bintray.apikey=key
bintray.gpg.password=password
...

Мой build.gradle для библиотечного модуля выглядит так:
