Не удалось разрешить зависимости, не удалось найти банку

Я пытаюсь запустить vaadin-charts-demo.

Проблема, аналогичная этой: Maven не может разрешить зависимости, артефакты не удалось разрешить

Tried googling vaadin-chart-examples and chart-demos maven, repository, etc., but haven't found a solution. How can this be resolved?

[[править]] Проект импортирован отсюда: https://github.com/vaadin/charts/tree/7a55e8dab5b9941a05603c2624a576866e86045d

Следуйте этим инструкциям: https://github.com/vaadin/charts/blob/7a55e8dab5b9941a05603c2624a576866e86045d/DevInstructions.md

После установки не удалось скомпилировать виджеты

Инструкции для Луны, я использую Марс, не знаю, как это повлияет на вещи.
