Ошибка Maven - Ошибка авторизации: не авторизован прокси-сервером

Я пытаюсь создать opennms в ubuntu. Но когда я даю ./compile.pl (для компиляции исходного кода opennms) в терминале, я получаю ошибку ниже. Я использую версию maven 2.2.1. Could anybody please provide a solution.

Note: removed the hyperlink like http in stacktrace..
